3 1 Introduction This Certification is the sole property for copyright to Mr. Ted Bennett of Civil & Structural Engineering Design Services Pty. Ltd. The following structural drawings and calculations are for the transportable tents supplied by Extreme Marquees. The frame consists principally of extruded hot dipped galvanized steel trusses and base plates. The report examines the effect of 3s gust wind of 80 km/hr on 24.4m 12.2m x 6.4m The Platoon Tent as the worstcase scenario. The relevant Australian Standards AS1170.0:2002 General principles, AS1170.1:2002 Permanent, imposed and other actions and AS1170.2:2011 Wind actions are used. The design check is in accordance with AS/NZS 4100:1998 Steel Structures. 3 P a g e

4 Design Restrictions and Limitations Civil & Structural Engineering Design Services Pty. Ltd. 2.1 The erected structure is for temporary use only. 2.2 It should be noted that if high gust wind speeds are anticipated or forecast in the locality of the tent, the temporary erected structure should be dismantled. 2.3 For forecast winds in excess of (refer to summary) all fabric shall be removed from the frames, and the structure should be completely dismantled. (Please note that the locality squall or gust wind speed is affected by factors such as terrain exposure and site elevations.) 2.4 The structure may only be erected in regions with wind classifications no greater than the limits specified on the attached wind analysis. 2.5 The wind classifications are based upon Terrain Category 2. Considerations have also been made to the regional wind terrain category, topographical location and site shielding from adjacent structures. Please note that in many instances topographical factors such as a location on the crest of a hill or on top of an escarpment may yield a higher wind speed classification than that derived for a higher wind terrain category in a level topographical region. For this reason, particular regard shall be paid to the topographical location of the structure. For localities which do not conform to the standard prescribed descriptions for wind classes as defined above, a qualified Structural Engineer may be employed to determine an appropriate wind class for that the particular site. 2.6 The structures in no circumstances shall ever be erected in tropical or severe tropical cyclonic condition as defined on the Map of Australia in AS , Figure The tent structure has not been designed to withstand snow and ice loadings such as when erected in alpine regions. 2.8 For the projects, where the site conditions approach the design limits, extra consideration should be given to pullout tests of the stakes and professional assessment of the appropriate wind classification for the site. 2.9 The tents are stabilized as using roof/wall cross bracing at end bays as shown on the drawings. 4 P a g e

21 6 Summary 6.1 Conclusions a. The 12.2m x 24.4m The Platoon Tent structure as specified has been analyzed with a conclusion that it has the capacity to withstand wind speeds up to and including 80km/hr. b. For forecast winds in excess of 80km/hr all fabric shall be removed from the frames, and the structure should be completely dismantled. c. Wall cross bracing as well as roof cable bracing are required at each end bay to resist against lateral movement due to wind direction2. d. For uplift due to 80km/hr, 10 kn (1T) holding down weight/per leg for upright support is required. e. The bearing pressure of soil should be clarified and checked by an engineer prior to any construction for considering foundation and base plate. f. Bracing Cables are required to have the minimum tensile strength (SWL) equal to 10kN. g. Design of fabric by others. Yours faithfully, E.A. Bennett M.I.E. Aust. NPER P a g e
