Question: The cross section of a concrete dam is shown in Figure. Using a simple plane frame model, estimate stresses in the-darn due to self-weight of the dam and the water pressure. Use a reasonable number of elements and assign average section properties to each element. Assume unit thickness perpendicular to the plane. The depth of the water behind the dam is 18m, The density of concrete is 2400 kg/m3 and that of water is 1000 kg/m3. The modulus of elasticity of concrete is 30 GPa.
