Out-of-Plane Performance Evaluation of Brick Masonry Infill Wall Using Shaking Table Test Part 1 Experimental program

摘要

Brick masonry wall is widely used as infill in RC buildings evenin the countries with high seismicity because of its low cost ofconstruction and availability. Although the infill wall isconsidered as a nonstructural element, previous studies showthat it also affects the seismic performance of the whole building.However, those studies focus on the contribution of infill wallconsidering only the in-plane direction as it provides the loadpath for transferring the seismic forces. In contrast, seismicforces in both in-plane and out-of-plane directions act on theinfill walls during an earthquake. If the infill wall is not strongenough, out-of-plane collapse occurs and changes itscontribution to the seismic performance of the building whichalso causes significant danger to life safety.This shows that it is necessary to estimate the out-of-planeresistance of the infill wall to predict its impact on the seismicperformance of RC buildings with infill walls more accurately.Hence, this study was performed to experimentally investigatethe out-of-plane behavior and to propose an analytical model toestimate the out-of-plane resistance of brick walls.
