3-Dimensional Contribution to Frame-Wall Lateral Behavior

Abstract

Behavior of the first floor of the U.S.-Japan seven story reinforced concrete test structure was modeled by a finite element model. The constitutive matrix describing material behavior is a normal concrete model which included a smeared cracking capability. The computed response of the system was shown to have a dependence on the level of tension stiffening present in the concrete. The selection too Iowa value distorted the behavior observed in the model. The 3-dimensional effects presented in the test structure was also observed in the computational model. Motion of the tension I column was transmitted through the slab and beams to the outer frames. This mechanism . provided a significant contribution to the lateral load resistance.
