本文简要介绍石家庄79型框架轻板建筑整体破坏性试验研究目的、模型设计、主要测试结果以及基于试验研究、分析所得出的主要结论和抗震设计的建议。试验研究的主要结论是: (1)用几种测试方法测得的结果是基本一致的,可见测试数据是可靠的。试验结果表明:推——拉反复加载方法是很重要的,能得出与地震破坏现象相类似的特征。 (2)楼板在平面刚度很大,为简化计算可假定为无穷大。 (3)框架横梁的有效翼缘宽度可取跨度的1/3。 (4)试验结果的延伸率很大。 (5)结构抗7度地震是安全的。
This article briefly introduces the overall destructive test research objectives, model design, main test results, and the main conclusions based on experimental research, analysis and seismic design recommendations of the 79-frame light-frame building in Shijiazhuang. The main conclusions of the experimental study are: (1) The results obtained with several test methods are basically the same, showing that the test data is reliable. The test results show that the push-pull repeated loading method is very important, and similar characteristics to the earthquake damage phenomenon can be obtained. (2) The floor slab is very rigid in the plane and can be assumed to be infinite for simplified calculations. (3) The effective flange width of the frame beam may take 1/3 of the span. (4) The extension of the test results is large. (5) The earthquake with structural resistance to 7 degrees is safe.
