某医院综合楼结构消能减震设计

Structural design using energy dissipation devices for a hospital building structure

对某高层框架-剪力墙结构进行了结构设计和有限元分析计算,工程中对结构采取了消能减震设计并进行了阻尼器性能试验。介绍了结构设计特点,包括结构选型、阻尼器选择与布置,并采用ABAQUS软件对结构进行了多遇及罕遇地震作用下的有限元分析。对比了不同地震波作用下的结构弹塑性分析结果,结果表明消能减震措施提高了结构的抗震性能。

Structural design and Finite element simulation of a hospital building was studied. Energy dissipation technology was applied in seismic design and tests of dampers performance were conducted. Features of structure design, such as structure form selection,damper selection and layout were introduced. Performance of structure was studied under frequent and rare earthquakes,through finite element software called ABAQUS. The results of the elasto-plastic timehistory analysis under three different earthquakes were compared and it is found that treatment measure and the energy dissipation design to the limited-beyond high-rise building improved the structure's seismic performance.
