设置构造柱和圈梁是提高砌体结构房屋抗震能力的有效措施。针对传统砖混房屋R.C.圈梁、构造柱的复杂工艺,提出了HPFL与砖砌体形成组合圈梁构造柱的简易形式。通过HPFL窄条带组合砖圈梁构造柱的足尺寸模型震动台试验,观测、分析HPFL窄条带组合砖圈梁构造柱结构的抗震能力。试验结果表明:HPFL窄条带组合砖圈梁构造柱的抗震效果较好,既可以对已有砌体房屋进行加固,也适用于新建砌体房屋,可代替传统的圈梁构造柱。根据试验结果和理论分析,将砌体结构所受的地震作用分成墙体及框架结构两部分计算,提出了HPFL窄条带抗震计算公式,可供工程结构设计参考使用。
It is an effective measure to improve the seismic resistance of masonry structure houses by providing structural columns and ring beams. Aiming at the complicated process of R.C. ring beam and structural column of traditional brick-concrete house, a simple form of HPFL and brickwork is proposed to form a composite ring beam structural column. Through the shaking table test of full-size model of HPFL narrow strip composite brick ring beam, the seismic performance of HPFL narrow strip composite brick ring beam is observed and analyzed. The test results show that the HPFL narrow strip composite brick ring beam has better seismic performance, which can not only reinforce the existing masonry buildings, but also apply to the new masonry building instead of the traditional ring beam structure columns. According to the test results and theoretical analysis, the seismic action suffered by the masonry structure is divided into two parts: the wall and the frame structure, and the formula for calculating the seismic resistance of the HPFL narrow strip is proposed, which can be used as a reference for engineering structural design.
