六层大开间轻型格构板模型房屋抗震试验研究

Study on Earthquake Resistant Experiment of a Six-story Light Latticed Panel Model House with Large Bays

在９祸格构式墙板抗震试验研究[１］基础上，进行了六层大开间１／２比例轻型格构板整体模型房屋低周反复加载试验和拟动力试验。通过锤击试验和脉动法，获取了模型结构在空载、配重及不同破损阶段的动力特性。分析了在地震作用下模型结构裂缝发生、发展规律及其破坏机制，测量了模型房屋开裂荷载、极限荷载及在相应荷载下的变形，并据此推算原型格构板房屋结构的抗震承载力。

On the basis of seismic test of 9 latticed panels, a low cyclic reverse loading and pseudo-dynamic test of a six-story 1/2 scale model house was carried out. By means of hammerblow and pulse methods, different dynamic characteristics of the model structure on the stage of zero load, balance load and different failure states were acquired. The crack and its mechanism of the model house under earthquake were analyzed, and the cracking load, limited load and the correspondent deformation were measured, from which the seismic bearing capacity of the prototype was evaluated.
