Thin reinforced concrete (RC) walls with single layer reinforcement have been used for houses and buildings in several Latin American countries. Although some design codes include recommendations for squat thin walls in low-rise constructions, its seismic performance has not been validated adequately in past earthquakes. This article presents the results of an experimental campaign of nine full-scale specimens conducted to characterize the influence of the steel type, the reinforcement ratio, and the wall thickness on the seismic behavior of squat thin RC walls with single layer reinforcement. Both welded wire and deformed bars were used as web reinforcement. Experimental results are used to develop nonlinear models to assess the seismic behavior of a prototype two-story house with welded wire reinforcement and deformed bars by means of incremental dynamic analyses. The experimental results show that the type of steel has the largest influence on wall seismic performance. The numerical results suggest that RC walls with single layer reinforcement are suitable for housing applications up to two stories in high seismicity regions, particularly walls detailed with deformed bars.

低层建筑矮钢筋混凝土薄壁抗震性能

具有单层钢筋的薄钢筋混凝土 (RC) 墙已在几个拉丁美洲国家的房屋和建筑物中使用。尽管一些设计规范包括在低层建筑中采用矮墙的建议，但其抗震性能在过去的地震中并未得到充分验证。本文介绍了九个全尺寸试样的试验结果，该试验旨在表征钢类型、配筋率和壁厚对单层钢筋钢筋混凝土薄壁的抗震性能的影响。焊丝和变形钢筋都用作腹板加强筋。实验结果用于开发非线性模型，以通过增量动力分析评估带有焊接钢筋和变形钢筋的原型两层房屋的抗震性能。试验结果表明，钢材的种类对墙体抗震性​​能的影响最大。数值结果表明，具有单层钢筋的 RC 墙适用于高地震活动地区高达两层的住宅应用，特别是带有变形钢筋的墙。
