Section Optimization of Diaphragm Wall
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
Diaphragm wall is common type of earth retention system. Diaphragm walls are generally used in deep basement of building, congested urban spaces, riverfront structures and marine structures. The stability is provided through an embedment of the wall on the ground, working as a cantilever structure and may be with a system of anchors, so the wall is subject to shear stresses and bending moments. Study aims to find an optimal section for a diaphragm wall considering variations in many of its design parameters to suit the soil conditions and depth of excavation. The effects of variations of these design parameters will be compared to get an optimized section. The parameters which are selected for the study are panel shape, panel thickness, and maximum panel length and panel width and soil conditions. Comparison has to be done with the bending moment and head displacement for different diaphragm wall shapes, panel width and panel thickness using SAP2000 software. 1st studied the effect of diaphragm wall by changing panel length as 2.5m, 3.5m, 4.5m and 5.5m and panel thickness as 0.6m, 0.8m and 1.1m for both rectangular section and T section. 2nd study is about the effects while changing the depth of the web in the T section.
