E-Defense Shake-table Test of a Building Designed for Post-disaster Functionality

ABSTRACT

Shake-table tests of a 3-story reinforced concrete building with cladding casted to be monolithic with frame elements, with seismic slits or cut reinforcing bars present in some cladding elements to ensure a desirable deformation mechanism, was performed at E-Defense to evaluate its post-disaster functionality. The building satisfied response objectives; behaving elastically with 0.33% drift or less during a “severe earthquake motion” defined in the Japanese Building Standard Law, and has a base shear capacity coefficient greater than 0.55. However, the damage was greater than expected due to deformations concentrating on a few cracks, resulting in continuous functionality not necessarily being achieved.
