摘要
对结构超强进行了大量研究,结果表明多自由度体系在地震作用下存在明显超强,根据其研究成果和震害经验的总结,得出国外不少抗震设计规范对结构类型和超静定次数的不同考虑了不同程度的超强,而我国在这方面的研究成果相对较少,规范也未对此做出相关规定的结论。
The article have studied comprehensively on overstrength of structure, it is found that MDOF systems have obvious overstrength under earthquake. According to their research results and summary on the experience of earthquake damage, many foreign seismic codes have take into account overstrength factor varied with structure type and the degree of statical indetemainacy. However, there is only a small quantity of correlative research results in our country, and seismic code is not into account overstrength.
