Wallap Wall deflection assesment

[G J S Krishna]

Hi All.
I have one question. i am working in Wallap for one Diaphragm wall design. i just want to know wall displacement behavior with change in wall moment of inertia by changing wall thickness (ie. will change wall flexural rigidity). but what i observed from results is that there is certain reduction in wall displacement with increase in Wall moment of inertia. but after certain point there is no reduction in wall displacement even there is considerable increase in moment of inertia.

What is the reason behind this? can anyone elaborate on this!!!

By increasing the inertia at some point the wall will "effectively" be rigid, but it can still undergo rigid body rotation. Increasing the inertia further will have no effect. You could try increasing the toe depth of the wall or increase the stiffness of the anchors/struts.
