［摘要］云南7度（0-15g）区某医院住院楼是采用铅芯橡胶支座隔震的钢筋混凝土框架-剪力墙结构，建筑高度71-25m，为高层建筑，建筑平面呈L形。该建筑受限于建筑平面，不能采用防震缝分开，通过在地下室顶板和首层之间的夹层布置铅芯橡胶支座，改善了结构抗扭性能。设防地震和罕遇地震下的分析结果表明，结构各项计算指标均能满足规范要求，结构抗震性能大大提高。论述了该高层隔震结构设计中的关键问题,如最小剪力系数的控制、隔震支墩的计算、隔离缝的处理。

Abstract:A hospital patient building in area of 7-level（0-15g）in Yunnan adopts the isolated   reinforced concrete frame-shear wall structure with the lead-rubber bearing. The building height is 71-25m, which is  a high-rise building and the plane of the building is L shaped. The building can not be separated by the aseismic joint due to the limit of building plane. Through the arrangement of the lead-rubber bearing between the basement roof and the ground floor，the torsional performance of the structure was improved. The calculation results show that all the calculation indexes of the structure can meet the requirements of codes, and the seismic performance of the structure is greatly improved under fortification earthquakes and rare earthquakes. The key problems in the design of the high-rise isolated structure were discussed, such as the control of the minimum shear force coefficient, the calculation of the isolation bearing and the treatment of the separation joint.

Keywords:high seismic fortification intensity zone; high-rise structure; frame-shear wall structure; lead-rubber bearing; seismic isolation technique; shear force coefficient; aseismic joint
