Figure 1 shows the plan view of an Exhibition Hall with dimensions L1 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 sulphate and other organic compounds. The layout of the structure consists of portal frames which are spaced evenly along the L2 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.
