A proposed residential development of a single tower is to be built on a sloping site as shown in Figure 1. The site has a (W1m x 25m wide building zone. A level platform has to be created by building a permanent retaining structure outside the building zone but within the (W2m x (W2m wide site boundary. A temporary slope, which may extend outside the site boundary, has to be formed in advance for construction of the retaining structure. ---...

Ideal Column with Pin Supports Learning Goal: To use the formula for the critical load, i.e., the Euler buckling load, for pin-supported columns to calculate various parameters of columns. Ideally, a column that is perfectly straight and has an axial load applied exactly at the centroid of its cross section will not yield until the internal normal stress reaches the yield stress of the material. Real-world columns, however, are subject to small asymmetries, whether due to irregularities of shape or...
