ABSTRACT

The out-of-plane collapse of masonry infills during seismic actions resulted in human life losses and huge repair or reconstruction costs. These problems will result in disturbance of the operational functions of the buildings. The main scope of this research is to analyze the efficiency of different strengthening techniques based on textile reinforced mortar (TRM) technique and using steel connectors in the out-of-plane direction. To accomplish the objectives, four half-scale specimens were tested under uniform out-of-plane loads applied by an airbag to each mass of the infill cyclically. The performance of the textile reinforced mortar technique by using two different meshes was also evaluated experimentally. Besides the protection of the infill from collapsing and protection of human lives, using TRM technique enhances the out-of-plane response of the specimen but its connection to the infill has to be deeply investigated.

摘要

地震作用期间砌体填充物的平面外倒塌导致人员伤亡和巨大的维修或重建成本。这些问题将导致建筑物的运行功能受到干扰。本研究的主要范围是分析基于纺织增强砂浆 (TRM) 技术和在平面外方向使用钢连接件的不同加固技术的效率。为实现这些目标，四个半比例样本在均匀的平面外载荷下进行了测试，这些载荷由气囊循环施加到每个填充物的质量上。还通过实验评估了使用两种不同网格的织物增强砂浆技术的性能。除了保护填充物免于倒塌和保护人的生命外，
