[提要] 在樓板分區(qū)剛性假定的基礎(chǔ)上，以彈性變形梁模擬空中連廊的變形，建立了時(shí)程分析的復(fù)合剛片系振動(dòng)模型。引入砌體的滯回特性，該模型可用于復(fù)雜體型砌體結(jié)構(gòu)房屋彈塑性地震反應(yīng)時(shí)程分析。文末對(duì)大底盤雙塔樓帶連廊砌體結(jié)構(gòu)房屋的地震反應(yīng)作了計(jì)算和討論。

Based on the assumption that the floor is infinitely rigid in different areas and that the spatial corridors can be modeled as an elastic beam, a composite rigid panel series model is presented. By introducing the hysteretic behavior of masonry, this model can be used for the elasto-plastic time history analysis of masonry buildings with complex configuration. Finally, the seismic responses of a double-towers masonry building linked by spatial corridors with enlarged base at the bottom are discussed.
Keywords: masonry building; enlarged base; multi-towers; spatial comdors; composite rigid panel model
