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.

摘要

在 E-Defense 进行了 3 层钢筋混凝土建筑物的振动台测试，该建筑物的覆层与框架元件一起铸造成整体，在一些覆层元件中存在抗震缝或切割钢筋以确保理想的变形机制，以评估其灾后功能。建筑物满足响应目标；在日本建筑标准法中定义的“严重地震运动”期间，具有 0.33% 或更低漂移的弹性表现，并且具有大于 0.55 的基础抗剪承载力系数。然而，由于变形集中在一些裂缝上，损坏程度比预期的要大，导致不一定能实现连续的功能。
