摘要
进行了 12层 1 3比例密肋壁板结构房屋模型的拟动力和伪静力试验。通过锤击试验和层间刚度测试 ,得到了结构的变形特征及其动力特性。分析了模型房屋在地震作用下裂缝发展规律、破坏机制 ,以及结构的抗震承载力、延性及耗能能力。试验研究表明 :密肋壁板结构受力合理 ,具有多道抗震防线 ,是一种理想的抗震结构体系。
The pseudo-dynamic and pseudo-static tests for a 1-3 scaled model of 12 storeys multi-ribbed wall slab building structure has been carried out.Through the hammerblow test and the rigidity between floors test,that the deformation characteristics and the dynamic property for structure of model are obtained.Under the seismic action,that the development regularity of cracks and the failure mechanism of building model,as well as its structural aseismic bearing capacity,the ductility and the capacity for dissipation of energy have been analyzed.The results of experimental study is shown that the multi-ribbed wall slab building structure has rational load-bearing ways and mulit-defense lines for earthquake-resistant,it is an idel aseismic structure system.
