连体结构楼板的性能化设计

Performance Design of Conjoined Structural Floors

连体结构型式和连体与主体的连接方式,对主楼的结构受力和抗震性能影响较大。该文以某采用刚性连接的连体结构为例,基于性能化设计方法,针对连接体楼板提出了性能目标及分析设计措施,计算多遇地震、设防地震及罕遇地震作用下的楼板应力。计算结果符合预期性能目标及规范要求,顺利通过了超限审查,可为类似工程的设计提供参考。

The type of conjoined structure and the way of connection between the conjoined body and the main body have a great impact on the structural force and seismic performance of the main building. Based on a conjoined structure with rigid connections, and combined with the performance-based design method, this paper proposed performance targets and analysis and design measures for the conjoined floors, and calculated the floor stress under the action of frequent earthquakes, fortification earthquakes and rare earthquakes. The calculation results meet the expected performance targets and specification requirements, and successfully passed the over-limit review, which can provide a reference for the design of similar projects.
