(a) Xu.bal depends on the grade of concrete only (b) Xu.bal depends on the grade of steel only (c) Xu.bal depends on both the grade of concrete and grade of steel does not depend on the grade of concrete and grade of steel (d) Xu,bal
In Fig. 4-1, calculate the width in ft. of the concrete dam that is necessary to prevent the dam from sliding. The specific weight of the concrete is 150 lb/ft3 and the coefficient of friction between the base of the dam and the foundation is 0.42. Use 1.5 as the factor of safety (F.S.) against sliding. Will it also be safe against overturning?
Q2|| Answer with True or False of the folowing question: 1. The column capitals decrease the effective span of the slab. 2. The total thickness of flat slab, should be not less than 150mm 3. The drops are provided in flat slabs to resist bending moment. 4. Deflection in slabs can be controlled by using appropriate aspect ratio. 5. Direct design method is more accurate than equivalent frame method.
