Full-Scale Test on Seismic Performance of Masonry Structure

Abstract

For further study on effective seismic design requirements of masonry structure, two masonry buildings were designed and constructed according to common structure style in towns and villages. Two full-scale buidings were subjected to earthquake using pseudo-dynamic test and quasi-static test. This paper presents crack propagation of masonry structure, hysteretic behavior, deformation and stiffness degradation under horizontal seismic action. In this experiment, deformability and ultimate bearing capacity of confined masonry (CM) with tie-column and ring-beam is higher than common brick structure (BM). Confined masonry (CM) wall maintain integrity due to constraint of tie-column and ring-beam. These tests verify that tie-column and ring-beam system is an effective seismic requirement to enhance seismic performance of masonry structure.

Rural Masonry Isolating Structure and LRB Experiment: Seismic Resistance Properties and Statistical Data Curve Analyses

“…We obtained hysteretic curves with different levels of simulated seismic intensity according to the experimental data. We then analyzed the LRB equivalent horizontal stiffness, postyield stiffness, and equivalent viscous damping ratio mechanical properties [50] to compare them against those measured in the LRB factory to test the applicability of the proposed method. e postyield stiffness of the structural isolation layer is calculated as follows:…”
