The Fixedangle Softened Truss Model with Tensionstiffening (FASTMT) has a superior performance in predicting the shear behaviour of reinforced concrete (RC) membrane elements, especially for the postcracking behaviour. Nevertheless, massive computational work is inevitable due to the multiple transcendental equations involved in the stressstrain relationship. In this paper, an iterative rootfinding technique is introduced to FASTMT for solving quickly the transcendental equations of the tensionstiffening effect of RC membrane elements. This fast FASTMT, which performs in MATLAB, uses the bisection method to calculate the tensile stress of the membranes. By adopting the simplification, the elapsed time of each loop is reduced significantly and the transcendental equations can be solved accurately. Owing to the high efficiency and good accuracy as compared with FASTMT, the fast FASTMT can be further applied in quick prediction of shear behaviour of complex largescale RC structures.
