Numerical Study of the Behavior of Reinforced Concrete Shear Walls during Fire Exposure

Abstract:

A simple method based on the well-known sectional analysis approach is presented to trace the structural behavior of reinforced concrete (RC) shear walls exposed to fire. It is similar to the approaches described in the existing literature but it does not require computations of moment-curvature curve group. This method can take into account material nonlinearity by use of the coupling constitutive relation of materials. Moreover, the geometric nonlinearity is considered by taking account the second-order effect of axial forces. The predictions of the proposed method are validated using experimental and analytical studies.
