约束蒸压粉煤灰砖砌体结构抗震性能研究

研究了蒸压粉煤灰砖砌体结构抗震能力,采用非线性时程分析方法,分别对两栋典型的蒸压粉煤灰砖砌体结构进行了非线性地震反应分析,研究了在抗震设防＂三水准＂情况下结构的抗震能力。结果表明：在抗震设防烈度为7度和8度地区分别建造7层和6层约束蒸压粉煤灰砖砌体结构房屋,其抗震能力可以提高一度。

Seismic performance of the bound autoclaved fly ash bricks masonry structure

This paper studies the seismic capability of the autoclaved fly ash bricks masonry structure.By using a nonlinear time-history analysis method,a great number of the nonlinear seismic response analyses of two typical masonry structures with the autoclaved fly ash bricks are performed respectively.It studies the seismic capability on the seismic fortification ＂three level＂ cases.The analysis results show that a 7-or a 6-storey building of the autoclaved fly ash bricks are building in seismic fortification intensity of 7 degrees and 8 degrees regions,it can meet three level requirements of aseismatic fortify;The seismic capability of this kind of building can improve once.
