为提高我国农村地区低层住宅的抗震性能和保温隔热性能，提出了一种承重预制复合墙板结构，该结构采用现场组装的承重预制复合墙板，实现了适当的抗震性能和节能效果。采用承重预制复合墙板建造了1：2缩尺模型，进行了拟静力试验，得到了模型在模拟地震作用下的破坏特征、承载力和荷载-位移曲线。根据我国农村房屋结构抗震设计要求，对该结构的承载力、变形和耗能等抗震性能指标进行了评估。试验结果表明，原型结构的抗震能力比设计值提高了68%。该试件的延性系数为4.7，符合抗震性能要求，即此类混凝土结构的延性系数应超过3。设计可以进一步优化，以节省材料消耗。这表明，所研制的承重装配式组合墙板结构具有良好的承载力、延性和耗能能力，符合抗震设计规范要求。本文提出了一种基于工厂预制和现场组装的新的施工工艺，可大大降低能耗。
To improve both seismic performance and thermal insulation of low-rise housing in rural areas of China, this study proposes a load-bearing prefabricated composite wall panel structure that achieves appropriate seismic performance and energy efficiency using field-assembled load-bearing prefabricated composite wall panels. A 1:2 scale prototype built using load-bearing prefabricated composite wall panel is subjected to quasi-static testing so as to obtain damage characteristics, load-bearing capacity and load–displacement curves in response to a simulated earthquake. As a result, seismic performance indicators of load-bearing capacity, deformation and energy-dissipating characteristics, are assessed against the corresponding seismic design requirements for rural building structures of China. Experimental results indicate that the earthquake-resistant capacity of the prototype is 68% higher than the design value. The sample has a ductility factor of 4.7, which meets the seismic performance requirement mandating that the ductility factor of such concrete structures should exceed 3. The design can be further optimized to save the consumption of material. This shows that the load-bearing prefabricated composite wall panel structure developed here has decent load-bearing capacity, ductility and energy dissipation abilities, a combination of which is in line with the seismic design code. A new construction process proposed here based on factory prefabrication and field assembly leads to a considerable reduction of energy consumption.
