| Abstract | ||||
| . The diaphragm wall may collapse or the struts may fail as a result of the earthquake stresses. Because there has been little research on the dynamic performance and design of diaphragm walls and lateral braces, the present study focused on the behavior of diaphragm walls with lateral steel struts in sandy soil environment under seismic load using a finite difference modeling method using PLAXIS 2D software version 8.6. The experimental results were compared to the end-of-seismic-motion lateral displacements and bending moments in the wall. The study showed that in a post-seismic state, lateral displacement, bending moment, strut forces, and maximum ground surface displacement increased with excavation depth and the frequency of base acceleration when all other components were kept constant | ||||
