EPS模块剪力墙在不同剪跨比作用下的抗震性能的研究

Study on seismic performance of EPS module shear wall under action of different shear span ratio

为了解某新型材料剪力墙地震时的抗震性能,利用某公司生产的EPS空腔构造模块作为微型墙体在不同的剪跨比作用下进行抗震模拟试验。试验结果表明,模块剪力墙在承载能力、刚度退化和延性方面与普通剪力墙体有所差别,但仍然能表现出较好的抗震性能;EPS模块剪力墙随着剪跨比的提高,试件的极限承载力有所降低,但是由于剪跨比大的墙体刚度退化较慢,所以试件的延性有所提高,具有较好的抗震性能。

In order to understand the seismic performance ot me shear watt of a new type of material under the earthquake, the seismic simulation was conducted for the EPS cavity configuration modules produced by a company used as miniature walls under different shear-span ratio action. The test result indicates that, compared with common shear walls, the module shear walls are somewhat different in terms of bearing capacity, stiffness degradation and ductility, but they still present good seismic performance;The ultimate bearing capacity of the EPS module shear walls decrease somewhat, with the increase of shear-span ratio, but due to slow stiffness degradation of walls with large shear-span ratio, the ductility of the specimen somewhat improves with better seismic performance.
