某砌体支墩式消能减震建筑结构分析

Analysis of masonry buttress energy dissipation and shock absorption building structure

以一栋3层框架结构小学教学楼为减震研究对象,采用砌体支墩式消能减震技术,以及ETABS空间分析程序,对设防地震作用下的结构弹性和罕遇地震作用下弹塑性分析,得到消能减震结构的楼层剪力、层间位移角、能量耗散、塑性发展等,对该结构体系的抗震性能进行综合评价。结果表明,结构整体和关键构件满足设计要求,结构抗震性能良好。砌体支墩式消能易施工,能够充分发挥塑性耗能能力,有效保护主体。

Taking a 3-storey primary school teaching building as the seismic research object,the frame structure adopts masonry support pier-type energy dissipation and damping technology,adopts the ETABS spatial analysis procedure,analyzes the structural elasticity under the action of fortified earthquakes and the elastoplasticity under the action of rare earthquakes,and obtains the floor shear force,interstational displacement angle,energy dissipation,plastic development,etc.of the energy dissipation shock absorption structure,and comprehensively evaluates the seismic performance of the structural system.The results show that the overall structure and key components meet the design requirements,and the seismic performance of the structure is good.Masonry support pier type energy dissipation is easy to construct,can give full play to the plastic energy consumption capacity,and effectively protect the main body.
