常州市某综合病房大楼平面由两个叠角矩形结构组成,结构于裙房顶收进形成退台,尺度较大且复杂,属超限高层结构。结构形式采用框架和三个筒体组成的框架-剪力墙结构。针对结构平面叠角和竖向收进,采用了基于性能的抗震设计,在宏观上把握结构的薄弱部位,有针对性地采取加强措施。计算结果表明,结构的工作状态和性能均能达到设计的预期性能目标和规范要求。局部密肋楼板和预应力混凝土梁的运用保证了建筑功能的实现。 Changzhou City, an integrated ward building plane consists of two stacked rectangular structure, the structure of the income into the formation of skirts set back Taiwan, the scale of large and complex, is an overrun high-rise structure. Structural form of the frame and three cylinder frame - shear wall structure. Aiming at the stacking angle and the vertical direction of the structure, a performance-based seismic design is adopted to grasp the weak parts of the structure macroscopically and to take targeted measures. The calculation results show that both the working status and the performance of the structure can meet the expected performance objectives and specifications of the design. The application of local ribbed slabs and prestressed concrete beams ensures the realization of building functions.
