Summary This report discusses the structural analysis of an aluminium dome roof for tank FB 2110 with diameter 60,7 m. The analysis is carried out according to the following applicable Eurocodes with Dutch national appendices: EN 1990: EN 1991-1-1: EN 1991-1-3: EN 1991-1-4: EN 1999-1-1: Basis of structural design Densities, self-weight, imposed loads for buildings General actions - Snow loads General actions - Wind actions Design of aluminium structures General structural rules The goal is to translate the current dome calculations prepared according to the American code API 650 to the European Eurocode standards listed above in order to ease interpretation for classification societies. The analyses in this report are solely based on data presented in CST project No 216197, attached in Appendix A. It is concluded that all struts in the aluminium dome roof for tank FB 2110 with diameter 60,7 m, specified in Appendix A, comply with the conditions and criteria set out in the Eurocode EN 1990, 1991, and 1999. 3
General data Design life and consequence class The dome roof is classified to have an indicative design working life of 50 years according to design working life category 3 in Table 2.1 of EN 1990. Furthermore, the dome roof is categorised under consequence class CC1 according to Table B1 of EN 1990. The accompanying partial safety factors according to Table NB.5 of NEN EN 1990 NB are: =1.20 max (0.90 where unfavourable) combined with, =1.10 max (0.90 where unfavourable) combined with and, =1.35 max (0.00 where unfavourable) Materials The dome roof is made of aluminium 6061-T6 with properties according to Table 3.2b of EN 1999-1-1, which are: 6061-T6 Density [kg/m 3 ] 2700 Young s modulus [MPa] 70000 Poisson s ratio [-] 0.33 Yield stress [MPa] 240 Buckling class [-] class A Partial safety factor [-] 1.10 Partial safety factor [-] 1.25 table 1: Material properties Wind class The dome roof will be installed in Amsterdam, The Netherlands. This site is located in wind area I according to Figure NB.1 of NEN EN 1991-1-4. Characteristic values of actions The following actions are taken into account for the dome roof analysis. Loads acting downward are taken positive, loads acting upwards are taken negative. Dead Load The total dead load is equal to (Appendix A, page 4): = 0.142 kn/m 2 Live Load The dome roof is classified under category H: roofs according to Table 6.9 of NEN EN 1991-1-1. According to Table 6.10 and Appendix A, page 4 the associated total live load is equal to: The accompanying factors for category H buildings are: = 0.718 kn/m 2 =0, =0, =0 4
Internal vacuum There is no internal vacuum applied to the tank. Internal pressure There is no internal pressure applied to the tank. Water accumulation Water accumulation is not a factor due to the slope of the dome roof. Snow loads The snow loads are computed according to EN 1991-1-3, which states: = with = 1 is the exposure coefficient, = 1 is the thermal coefficient. Parameter is the characteristic value of snow load on the ground. According to NEN EN 1991-1-3 NB paragraph 4.1 all sites in The Netherlands should use a value of = 0.7 kn/m 2. As stated by EN 1991-1-3 the shape coefficient for cylindrical roofs are given in the following expressions: >60 =0 60 =0.2+10 h/ with =2.0 These expressions and associated parameters are visualised in Figure 5.5 and 5.6 from EN 1991-1-3 as shown below. The maximum roof inclination angle is given by the cut-off angle 1 2 = 3.6 in Appendix A, page 4. With a dome rise h = 3 = 12.07 m and an anchor bolt diameter = = 60.67 m, both taken from Appendix A, page 4, it is found that: = 2.189 As shown in the figure above it is required to consider two cases: the undrafted load arrangement (case i) and the drifted load arrangement (case ii). These cases result in: Case i: =0.8 = 0.560 Case ii: 0.5 = 1.095.5 = 0.766 = 2.189. = 1.533 A conservative estimate of the average load for the full roof surface area is given by the maximum of either or. /2, given by: = =max,. = 0.766 kn m2 2 According to NEN EN 1990 NB the accompanying factors for snow loads concerning category H buildings are: =0, =0.20, =0 5
Wind loads The wind loads are computed according to EN 1991-1-4. The expression for the wind load is: = where is the peak velocity pressure as a function of the dome roof height. The current dome roof height is equal to =29,6 m. Interpolation in Table NB.5 of NEN EN 1991-1-4 NB for wind area I, without buildings provides a peak velocity pressure of: = 1.42 kn/m 2 The dome roof does not have a dominant size and is fully closed, i.e. there are no openings. Therefore, the internal pressure coefficient should be taken equal to: = 0.20 The external pressure coefficient will be determined by means of Figure 7.12 of EN 1991-1-4, given below. With a dome rise = 3 = 12.07 m, a diameter = 4 / = 60.67 m, and a tank height of h = = 29.6 m the following ratios are obtained:, = 0.99, h/ = 0.488 Linear interpolation of these ratios in the figure above results in the following external pressure coefficients for locations A, B, and C: Substituting these values into the expression for gives: = -0.96, = -1.036, = -0.479 = cos 1 2 = cos 1 2 = -.1.20 kn/m 2 = = = -1.761 kn/m 2 = cos 1 2 = cos 1 2 = -0.701 kn/m 2 where cos transforms the normal pressures to vertical pressure components. For locations A and C the angle corresponds to the cut-off angle in Appendix A, page 4. For location B the normal pressure is already directed vertically, giving a zero angle, resulting in cos 0 =1. For the analysis, the following average wind load will be used: = +2 + 4 = -1.356 kn/m 2 6
According to NEN EN 1990 NB the accompanying factors for category H buildings are: =0, =0.20, =0 Load combinations In the previous section the following actions have been determined (downward positive, upward negative): Value [kn/m 2 ] Dead load total 0.142 Live load total 0.718 Internal vacuum 0 Internal pressure -0 Snow load 0.766 Wind load -1.356 table 2: Characteristic values of actions Given these actions, three load combinations will be considered: 1 = 1.2 = 0.17 kn/m 2 2 = 1.1 + 1.35 + 0.4 6 = 1.19 kn/m 2 3 = 0.9 + 1.35 + 0.4 = -1.70 kn/m 2 Load combination ULS2 is the critical downward combination and ULS3 is the critical upward combination. Please note that the internal vacuum and internal pressure loads are multiplied by a ratio of 0.4, which is the ratio between normal operating pressure and design pressure of the American code API 650. Not applying this ratio factor would result in double built-in conservatism, both from the American as well as the European code. Structural analysis The structural analysis of the dome roof, as presented in Appendix A, is executed by the TEMCOR computational software. Both the input load combinations as well as the resulting stresses can be found in Appendix A. In this report no check will performed on the correctness of input or output data in Appendix A. It is assumed that the dome plate material attachment to the struts is strong enough, such that buckling about the minor axis is prevented and that the compressed upper flanges are not sensitive to lateral torsional buckling. Conversion factors The critical downward and upward load combinations in Appendix A are: Case 2: Dome dead load + dome live load = 0.86 kn/m 2 Case 4: Dead + ASCE wind case A = -1.04 kn/m 2 According to the Eurocode the critical downward and upward load combinations (from the previous section) are: ULS2: 1.19 kn/m 2 ULS3: -1.70 kn/m 2 This means that the output forces and moments for the critical downward and upward load cases from Appendix A need to be multiplied by the following conversion factors in order to correspond to the load combinations stated by the Eurocode:. 0,12 =1.3.. 0, = 1.64 7
Critical strut selection With the conversion factors known, the next step is to make a selection of critical struts from the consolidated stress summary in Appendix A. The consolidated stress summary contains the most critical load case for each strut group. Further selection is based on: 1. the combined stress ratio 2. presence of compressive forces and consequently sensitive to buckling 3. the cross-sectional strut type dimensions 4. the strut group length Not every strut type is necessarily considered. For example, if it is clear that the most critical force and moment for strut type E-123 are equal or lower than that of strut type E-456, when at the same time cross-sectional thicknesses of strut type E-456 are larger, or the length is lower, than it is obvious that the latter strut is less critical. Based on the above selection criteria, the following struts are selected from Appendix A: Strut type and group Length [mm] Critical load case E-609 #7 3355.4 Case 2: Dome dead load + dome live load E-614 #29 3410.8 Case 2: Dome dead load + dome live load COMP01 #30 5143.4 Case 4: Dead + ASCE wind case A table 3: Strut selection Forces and moments according to Eurocode Subsequently, the forces and moments for these strut groups will be multiplied by their corresponding factors determined above, resulting in the following forces (compression positive) and moments. Strut type and group [kn] [knm] E-609 #7 114.07 2.44 E-614 #29 118.72 17.17 COMP01 #30 972.88 9.46 table 4: Strut forces and moments according to Eurocode These forces and moments will then be tested according to EN 1999-1-1. Classification of cross-sections The role of cross-section classification is to identify the extent to which the resistance and rotation capacity of cross-sections is limited by its local buckling resistance. The classification of parts of cross-sections is linked to the values of the slenderness parameter as follows for beams: : class 1 < : class 2 < : class 3 : class 4 Parameters for internal (I) and external (SO) parts, as illustrated below, are: Internal parts: = 11. 11.23, = 16 = 16.33, = 22 = 22.45 External parts: = 3 = 3.062, = 4.5 = 4.593, = 6 = 6.124 with = 250/ = 1.021, and = 240 MPa. The above values for are valid for class A material without welds. 8
Using the parameters in the figure above the values for can be derived as follows: Pure compression: Pure bending: Internal parts: = / External parts: = / Internal parts: =0.4 / External parts: = / Given the fact that the beam loads in the dome roof are dominated by compression, rather than bending, is conservatively taken as: Internal parts: = / External parts: = / Based on the cross-sectional dimensions given in Appendix A, the struts considered obtain the following classification: Strut type and group Class for Class for Class for E-609 #7 4 4 4 E-614 #29 4 4 4 COMP01 #30 4 4 4 table 5: Classification of parts of cross-sections Local buckling resistance Local buckling in class 4 members is generally allowed for by replacing the true section by an effective section. The effective section is obtained by employing a local buckling factor to factor down the thickness. is applied to any uniform thickness class 4 part that is wholly or partly in compression. The factor is given by the expressions below, separately for different parts of the section, in terms of the ratio /, where and are defined above and the constants and are: Internal parts: =32, =220 External parts: =10, =24 The above values for and are valid for class A material without welds. Based on the cross-sectional dimensions given in Appendix A, the struts considered obtain the following local buckling factors: Strut type and group for for for E-609 #7 0.422 0.649 0.685 E-614 #29 0.969 0.811 0.811 COMP01 #30 0.999 0.885 0.885 table 6: Local buckling factors Applying the local buckling factors to the cross-sectional properties in Appendix A results into the following reduced cross-sectional properties: 9

Based on the applied forces and moments and given in table 4, the design resistances and given in table 8, and the buckling reduction factors given in table 9 and table 10 the struts considered show the following buckling criterion results: Strut type and group Buckling criterion E-609 #7 0.767 E-614 #29 0.645 COMP01 #30 0.830 table 11: Buckling criterion results of struts All struts satisfy the buckling criterion as for all struts it is smaller than 1.00. Conclusion It is concluded that all struts in the aluminium dome roof for tank FB 2110 with diameter 60.7 m, specified in Appendix A, comply with the conditions and criteria set out in the Eurocode EN 1990, 1991, and 1999. 11

ANALYSIS PROCEDURE This structure was analyzed on CST Covers proprietary dome analysis program using the stiffness method of analysis. The dome struts are modeled using three dimensional beam elements which consider torsion, bending about two axes, axial and shear deformation. Panel loads are transformed into triangular beam loads equal to the load times one third the adjacent panel area normal to the load. These beam loads are then transformed into components parallel and perpendicular to the plane of the beam web. Member dead load is applied as a uniform beam load along the length of the member using the strut area times the density of the specified material times a factor which accounts for the batten. Panel dead load is treated as another panel load. In addition to the beam loads, loads may be applied to the nodes if required. The program will handle multiple load combinations with each combination composed of multiple load types. The maximum member stresses have been calculated from individual member equilibrium equations using the member end forces obtained from the stiffness analysis procedure and the applied beam loads. Each beam is divided into 20 increments and forces and corresponding stress are calculated for each increment. Member allowable stresses are also calculated at each increment and compared to the computed stresses. Allowable stresses are computed in accordance with the formulas specified by the "Specifications for Aluminum Structures - Allowable Stress Design" (Sixth Edition, October 1994) as published by the Aluminum Association, Inc., Washington, D.C.. All the dome frame struts, tension ring and gussets are aluminum alloy 6061-T6 unless otherwise noted. All fasteners are either aluminum or stainless steel as specified. Sheet No. 3

The degree to which seismic effects have an impact upon a structure's design depends most significantly on the structure's density. Due to the low mass to volume ratio of the aluminum dome, seismic effects do not control the dome design, nor the base shear reactions. Rather, applied wind loading on the large surface area on the dome results in the largest horizontal shear reactions. Therefore, wind load cases are presented in these Design Calculations. Other applied load cases and load combinations have been considered in the design; however, only the controlling load combinations are included in the following Design Calculations. Sheet No. 4
