Figure 1 shows the plan view of an exhibition hall with dimensions L, x L2. The structure is to be constructed in a coastal region which will be exposed to mostly mild environmental conditions, and should provide a 1.5 hour fire resistance. It is known that the underlying foundation soil contains sulfate and other organic compounds. The layout of the structure consists of portal frames which are spaced evenly along the L; direction. The frames are to support a slab of thickness (t) that will cover the full area of the hall plan. The dead and live loads applied on the slab are G and Q (kPa), respectively. Figure 2 shows the elevation view of Frames B and D. All columns have a floor-to-floor height (H) and are monolithically connected to the beams. Columns are also fixed to the foundation at the base, and it may be assumed that all frames are fully braced. в с D E F А в с D E FG Figure 1: Plan of exhibition hall.
