Lecture 29 : Braced cuts [ Section 29.6 : Design of the structural members ]
Design of diaphragm walls:
For design of the diaphragm walls the wall is assumed to lie as a beam and the pressure distribution acting on it as shown in the figure
Fig 6.42 Load on Diaphragm wall
From the pressure distribution the exact moment and forces acting on the struts and the wall can be calculated. However, for all practical purposes, the maximum bending moment acting on the wall ( ) = / 10, where l = . Accordingly the section of the diaphragm wall is chosen based on the moment acting on it.
Design of wales:
The wales are structural members which transfers the load from the diaphragm walls to the struts thereby acting as beams. The design of struts is done as simply supported beams as shown in fig. 6.7.9. Maximum moment on wales = (p. ). /8.
