Lecture 29 : Braced cuts [ Section 29.6 : Design of the structural members ]
Design of the structural members
Design of struts:
The struts are the structural members whose function is to transfer the earth pressure coming on the diaphragm walls due to the earth pressure from the surrounding soil. For calculation of the struts loads, Peck (1969) proposed apparent earth pressure diagrams to be used for the designing of the bracing systems. The diagrams are given in figure.
