The optimum constitution of limit state function of earthquake resistant structures is researched.1.As a foundation of the research, a database of earthquake response tests on steel frame models has been established, in which about 100 tests results are included.2.The errors of response prediction by the bi-linear analysis model were studied in terms of the database. It is found that some response result such as permanent displacement is sensitive to the modal parameters, so it will not be suitable to select such a response result as the factor to constitute the optimum limit state function of earthquake resistance structures. On the other hand, the energy absorption and the maximum displacement can be predicted in view of engineering.3.An anquete investigation was carried out. The results show that the experts in structural engineering take the resistance deterioration as the most important criteria to judge the damage degree of steel frames.4.The damage degrees observed in tests on steel frames are classified into 4 degrees according to the amount of the resistance deterioration : 'No, Early, Considerable Deterioration.' and 'Complete Collapse.' The hypothesis of identical strain energy with linear-elastic response provides a practical prediction of damage degree to some extent.

建立了钢框架结构模型地震反应试验数据库，其中包括100多个试验结果，作为研究的基础; 2.利用该数据库，研究了双线性分析模型的反应预测误差。结果表明，永久位移等反应结果对模态参数较为敏感，不宜作为构造抗震结构最优极限状态函数的因素。另一方面，可以从工程的角度预测吸能和最大位移。结果表明，结构专家将抗力退化作为判断钢框架损伤程度的最重要标准。4.根据抗力退化的程度，将钢框架的损伤程度分为4个等级：“未退化、早期退化、严重退化”。”和“完全崩溃。线弹性响应应变能相等的假设在一定程度上提供了一种实用的损伤程度预测方法。
