Title: Shear Design and Analysis of Low-Rise Structural Walls
Author(s): S. T. Mau and Thomas T. C. Hsu
Publication: Journal Proceedings
Appears on pages(s): 306-315
Keywords: failure mechanisms; reinforced concrete;shear strength; shearwalk; stress-strain relationships; structural analysis; structural design.
Abstract:Based on equilibrium and compatibility conditions, as well as a new stress-strain relationship for softened concrete, a truss-model theory wlzs presented in a previous paper to predict the shear strength and behavior of low-rise reinforced concrete structural walls. The theory was compared to tests of 23 shearwalls and was found to be applicable throughout the loading history. However, the iterative procedure used to trace the load-deflection history is not suitable for design purposes. In this second paper of a series, a direct solution of the load-deflection history is obtained. Furthermore, it is shown that three different failure modes (under-reinforced, balanced and over-reinforced) can be clearly identified, depending on the relative contribution of longitudinal steel to that of the concrete. For each failure mode, an explicit formula is derived for the prediction of shear strength. A simple procedure is recommended for the shear design of low-rise structural walls and is illustrated by an example problem.
