中文摘要：

通过低周反复加载试验,研究了1个纯框架试件、4个填充墙框架试件和7个用夹板墙或碳纤维布加固填充墙后的框架试件的抗震性能,这些试件均为单层单跨钢筋混凝土框架。对各试件的破坏过程、破坏形态、承载力、极限变形、滞回曲线、骨架曲线、延性、耗能能力、碳纤维布应变等进行了对比分析。试验结果表明：填充墙框架和填充墙加固后的框架一般发生剪切型破坏,与纯框架发生柱脚和梁端弯曲破坏的破坏模式有明显差异;填充墙框架的承载力明显高于纯框架,用夹板墙和碳纤维布X型粘贴加固填充墙能进一步明显提高框架的承载力,而碳纤维布水平粘贴加固填充墙对提高框架承载力的效果不明显。填充墙框架的极限变形能力比纯框架明显降低,填充墙框架的极限层间位移角仍能达到1/50,而填充墙加固后框架的极限层间位移角仅能达到1/80。

英文摘要：

Through cyclic loading tests, it is researched the seismic behavior of one simple frame specimen, four brick infilled frame specimens and seven frame specimens infilled with brick walls strengthened with steel-meshed cement mortar or carbon fiber sheet. All of these specimens are one-storey one-span reinforced concrete frames. Failure process, failure modes, load carrying capacity, ultimate deformation, hysteretic curves, skeleton curves, ductility, energy-dissipation capacity and strain of carbon fiber sheet are compared among these specimens. Test results show that shear failure always happens for infilled frames and strengthened infilled frames, and this is very different with flexural failure at column bottoms and beam ends for simple frames ; the load carrying capacity of infilled frames is much higher than simple frames, and it can be increased by strengthening the infilled walls with steel-meshed cement mortar or X-shaped carbon fiber sheet, but the strengthening with horizontal carbon fiber sheet has no distinct effect on the load carrying capacity of the iniilled frames. The ultimate deformation of iniilled frames is much less than simple frames, and the ultimate interstory deformation of infilled frames can reach 1/50, but the ultimate interstory deformation of strengthened infilled frame can only reach 1/80.
