They use reinforced concrete core-walls without supplemental moment resisting frames in the seismic force resisting system. RC core-walls offer advantages of open and flexible architecture. In a core-wall building, resistance to seismic forces is provided by a reinforced concrete core. Three reinforced concrete specimens (L00A, L45A and L45B) of an L-shaped core-wall was constructed with 1/4.5 scale and statically loaded to study the effect of loading direction and the section configuration on the seismic behavior of the core-wall. L45A and L00A were the equilateral L-shaped walls, and L45B was the inequilateral L-shaped wall. L45A showed the deformation followed the Bernoulli’s theorem until R=+0.34%. However, after R=+0.5%, the deformation of concrete under compression progressed faster than the deformation of other region and the Bernoulli’s theorem was not satisfied any more at this deformation. A simple fiber model well simulated the lateral load - drift angle relation if the moment – curvature relation at the wall base region was properly modeled by considering pull-out of longitudinal reinforcement and local crushing of concrete. However, the analysis did not simulate the load – drift angle relation after R=+0.5%. It is because that the Bernoulli’s theorem was not satisfied after R=+0.5% since the local crushing of the concrete took place. Hence, the numerical model based on Bernoulli’s theorem was stiffer after R=+0.5%.
