Strengthening Existing Buildings for Earthquake Survival

这项联合合作研究将研究墨西哥城的钢筋和混凝土建筑，这些建筑的抗震性能较低，由抗震设计规定确定。随后，通过添加支撑元素或填充墙来加强这些，并且在强烈的地震地面运动中它们经历了损坏或没有损坏。将对使用混凝土填充钢支撑系统和填充墙的创新技术进行实验室试验，以提供适当的分析模型数据和性能数据，以便在补救加强建议中加以利用。

This joint cooperative research will study selected steel and concrete buildings in Mexico City which had low seismic resistance as determined from seismic design provisions. Subsequently, these were strengthened through addition of bracing elements or infill walls, and they experienced damage or no damage during severe earthquake ground motion. Laboratory experiments of innovative techniques using concrete-filled steel bracing systems and infill walls will be performed to provide appropriate analytical modelling data and performance data for utilization in remedial strengthening recommendations.
