What is it about?

This study describes a slender reinforced concrete shear wall experimental test under in-plane cyclic lateral load, and the development of an analytical model which uses the fiber method approach to consider hysteretic nonlinear constitutive material models behavior. The shear wall tested had bending behavior, since the amount of longitudinal reinforcing bars produced weak bending capacity compared to the shear strength. The analytical model tries to represent global and local behavior of the wall, and its calibration is based on reaching experimental parameters like area enclosed and secant stiffness on every loop. After the analytical model was calibrated, the relation between some performance points and damage states observed during the test is studied.

Why is it important?

This research provides guides to evaluate the structural performance of slender reinforced concrete walls based on experimental data and computational fiber models.

Perspectives

This research shows how computational fiber models can be used to predict the structural performance, so this modelling tool can be use to understand better the response of particular cases like the slender reinforced concrete walls and many other cases.
