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.
A sample of Achilles saturated with water has a mass of 1710 g. After heating in an oven, a constant mass of 1815 g is obtained. The density of solid Achilles seeds is 2.78 g/cm3. We are asked to calculate:
a) The water content and void ratio
b) The porosity and specific gravity of the clayey soil
c) The wet density of the clayey soil, the corresponding dry density and dry density
8. A prestressed concrete beam is subjected to the
following stress distributions:
Pi is the initial prestressing force, Pe is the effective
prestressing force, M, is the bending moment due to self-
weight, Ma and M, are the dead load and live load bending
moment, respectively.
The concrete has the following properties: fr = 6000 psi

Stress at ends
Using Table 22.1, evaluate whether the stresses at the center of the span and the end of the span comply with the
permissible stress limits. The beam is classified as U-class.
Provide justifications for each condition listed in the table.
Note: Calculated stresses are to be taken from the above diagram, and permissible stresses are to be calculated
using Table 22.1.
