SHEAR STRENGTH OF REINFORCED CONCRETE: PART I--MEMBRANE ELEMENTS SUBJECTED TO PURE SHEAR
This paper presents a simple noniterative method for predicting the ultimate strength and the mode of failure of reinforced concrete membrane elements subjected to pure shear. This method is a simplification of the results of the modified compression field theory (MCFT), which is the basis of an alternative design method in the latest editions of American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Specifications and the Canadian Building Code (CSA-A23.2). The shear strength is related to the amounts of transverse and longitudinal reinforcement and to the concrete strength in the element. To check the accuracy of the method, the observed shear capacity and mode of failure of 46 reinforced concrete panels subjected to pure shear are compared with the results of the method, and good agreement is obtained. Based on the new method, a limit on the maximum amount of reinforcement required to ensure yielding is proposed. Part II of this series of two papers extends the applicability of the proposed method to beams subjected to shear combined with bending moment and axial load.
