摘　　要：通过对有楼梯的框架结构、框架-剪力墙结构和剪力墙结构的地震反应分析,研究了不同类型结构中楼梯构件的受力性能。结果表明,在框架结构中当楼梯与主体结构共同工作时,楼梯中梯段板、梯梁和梯柱等构件的内力显著增大,且受力状态复杂,从而造成楼梯构件不同程度的破坏;在框架-剪力墙结构和剪力墙结构中,当楼梯与主体结构共同工作时,楼梯中梯段板的内力明显增大,且受力状态复杂,易造成梯段板的破坏;而梯梁、梯柱等所受内力较小,不易产生破坏。The seismic response of the frame structure, the frame shear wall structure and the shear wall structurewith staircase was analyzed, the mechanical properties of the staircase of different type structures were studied. Theresults showed that as the staircase and the structure working together in frame structure, the force of the staircasecomponents increases significantly and the stress state is complex, so the staircase components will be destroyed se-riously. As the staircase and the structure working together in frame shear wall structure and shear wall structure,the force of the stair board increases obviously and the stress state is complex, so the stair board is easy to destroy,while because the force of the ladder beams and ladder columns is small, the ladder beams and ladder columns willnot be destroyed.
