摘　　要：为研究水平往复荷载作用下模块化箱式集成房屋结构的受力性能,对整箱结构进行竖向荷载和水平荷载共同作用下的拟静力试验。试验结果表明:在竖向荷载作用下,试件整体竖向变形较小,试件未见损坏;水平往复荷载作用下,上下连接件发挥了较好的连接作用;整个往复加载过程中,大部分测点应变数据均在弹性范围之内。试件加载及卸载过程中,除局部墙板及附属结构出现局部破坏及脱落外,试件整体完好,满足其安全性要求。To study the mechanical behavior of the modular box-type integrated house structure under the horizontal cyclic loading,the quasi-static test of the full-box structure under the combined vertical and horizontal loading was carried.In the test,the vertical load was equivalently replaced by the weight,and the horizontal load was equivalent to the joint load.The overall mechanical behavior of the box was evaluated by the combined effect of the above loads.The test results indicated that the vertical deformation of specimens under the vertical loading was small,and the specimen was not damaged.Under the horizontal cyclic loading,the upper and lower connectors played a good connection.During the entire loading process,most of the strain data of the measuring points were within the elastic range.In the loading and unloading process of the specimen,the specimen was in intact except partial damage and falling off of the partial wall panel and the auxiliary structure,which meet its safety requirements.
