Abstract:
This paper describes the analytical modeling of medium-rise monolithic cast-in-place reinforced concrete (RC) shear walls where nonlinear shear deformations play a significant role in the wall response under lateral loads. The analytical models use a fiber element developed based on a microplane approach to account for combined axial, flexural, and shear effects in the nonlinear range. Low-rise shear-critical walls that fail in sheardominated failure modes are not within the scope of the paper. The verification of the analytical models is achieved based on comparisons of estimated global (for example, load versus deflection) and local (for example, reinforcement steel strains and limit states) behaviors with experimental measurements of RC wall specimens under reversed-cyclic lateral loading.
