楼板不规则开洞结构抗震性能研究
|
摘要
本文以一实际不规则结构为背景,对该原型结构进行抗震性能分析,并对其抗震设计提出相应的设计建议。通过振动台试验,研究原型结构在不同水准地震作用下动力特性的变化情况,考察原型结构在不同水准地震作用下的位移、加速度反应以及破坏形态、整体结构的扭转反应和薄弱环节等,同时对其破坏机理进行研究。结果表明:模型结构个别楼层平均位移比超过规范限值,说明结构存在扭转不规则超限,但超限程度较低,建议适当采取措施,以提高整体抗扭刚度。
The seismic performance of a practical irregular structure is analyzed in this paper,and the seismic design suggestions are proposed. The dynamic characteristics of the prototype structure under different level earthquake are studied by shaking table test. The displacement,acceleration response and failure pattern of the structure are obtained with the results of the test. The torsional response of the overall structure,weak links and its failure mechanism are studied. The result shows that the average displacements of exceptional floor exceed the specification limits,and the structure has less level overrun of torsional irregularity. Some appropriate measures are proposed in order to improve the torsional rigidity of the structure.
