[提要] 在楼板分区刚性假定的基础上，以弹性变形梁模拟空中连廊的变形，建立了时程分析的复合刚片系振动模型。引入砌体的滞回特性，该模型可用于复杂体型砌体结构房屋弹塑性地震反应时程分析。文末对大底盘双塔楼带连廊砌体结构房屋的地震反应作了计算和讨论。

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
