![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.
