Lecture 26:
Secondary Loads
Some types of loads on buildings are due to deformation. The deformation may be due to earth sliding or settling unevenly under the footings. This type of load can be avoided by properly designed footings on stable soil.
The deformation of a building may be caused by temperature change. To avoid excessive stresses, construction must provide for a certain amount of thermal expansion and contraction. The problem is described in the diagram below.
