［摘要］汶川地震震害表明，樓面采用多孔板結(jié)構(gòu)的多層砌體房屋，由于砌體質(zhì)量較差，或圈梁、構(gòu)造柱設(shè)置不足，或混凝土強(qiáng)度較低，導(dǎo)致墻體抗震承載力不足；樓面多孔板缺乏整體性，樓面結(jié)構(gòu)與墻體結(jié)構(gòu)不能構(gòu)成一個(gè)完整的空間結(jié)構(gòu)。在地震作用下，多孔板缺乏整體調(diào)節(jié)作用，致使大量房屋倒塌。提出了幾種針對(duì)該類結(jié)構(gòu)的加固方法，并進(jìn)行了多孔板粘鋼拼接靜載試驗(yàn)，其結(jié)果表明，加固后多孔板樓面脆斷的可能性能夠消除。

Abstract:Seismic damage of Wenchuan Earthquake shown that the floor of multi-story masonry buildings with fabricatied hollow slabs had following disadvantages: poor quality masonry, lack of enough ring beams and construction columns, low concrete strength, or all of them.These shortcomings led to low seismic bearing capacity of the walls and poor integral quality of fabricated hollow slabs. The floor and wall couldn’t form a whole spatial structure.  A large number of houses collapsed because of the poor integrity under earthquake. Some strengthening methods were proposed.Static load test of fabricated hollow slabs with bonded steel was carried out, and the result indicates that it is possible to avoid brittle fracture of fabricated hollow slabs.
Keywords:masonry structures; fabricated hollow slab; integrity; anti-seismic measures
