【摘要】：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。
[Abstract]:The installation of structural columns and ring beams is an effective measure to improve the seismic capacity of masonry buildings. Aiming at the traditional brick-concrete house, R. C. This paper presents a simple form of HPFL and brick masonry to form a composite ring beam structure column. The seismic capacity of HPFL narrow strip composite brick ring beam structure is analyzed by means of the shaking table test of the full size model of HPFL narrow strip composite brick ring beam. The experimental results show that the seismic effect of the structure column of the narrow band composite brick ring beam with the small band HPFL is better. It can not only reinforce the existing masonry buildings, but also be suitable for the new masonry buildings, and can replace the traditional ring beams and columns. Based on the experimental results and theoretical analysis, the seismic action of masonry structure is divided into two parts: the wall and the frame structure, and the formula for seismic calculation of HPFL narrow strip is put forward, which can be used for reference in the design of engineering structures.
