Abstract

A design equation is developed in this chapter to predict the in-plane flexural strength of unbonded PT-MWs. Using well-validated finite element models, a parametric study is performed to investigate the effect of different parameters on the wall rotation and compression zone length, including axial stress ratio, length and height of the wall, initial to yield stress ratio of PT bars and spacing between PT bars.
