Damage Evaluation and Limit States of Rocking Concrete Walls with Energy Dissipaters

Abstract

In recent earthquakes in Japan, it was difficult for some reinforced concrete buildings to maintain their functionality after earthquakes due to damage to nonstructural RC walls. Currently, society expects quick recovery, if not uninterrupted functionality, of buildings after earthquakes. In this paper, four hybrid rocking wall specimens, along with rocking wall and RC wall were tested to quantify the damage level and limit states based on the 2015 AIJ guidelines. The behaviour of hybrid rocking walls was modelled with amulti-spring model. As aresult, limit states of analyzed walls were successfully classified in agood agreement with experimental results.
