Summary

This paper presents a simple non-iterative method to calculate the full response (shear stress versus shear strain) of reinforced concrete membrane elements subjected to in-plane shearing stresses. With the proposed quadri-linear stress, the shear strain relationship models four major parts of the behavior: (1) the pre-cracking zone, (2) the transition zone after cracking, (3) the post-cracking zone, and (4) the ultimate zone. The method is applicable to membranes reinforced in the orthogonal directions. The information required to generate the response are the ratio and yield strength of the reinforcement in the two directions and the concrete compressive strength.

The shear stress-strain curves generated using the proposed method are compared with the experimental results from selected reinforced concrete membrane specimens available in the literature and a very good agreement is observed. The model also provides an accurate measure of the shear strain at estimated service load levels.
