A performance evaluation system is developed and applied to 2-story steel frame models, where design point search in the first-order reliability method is combined with computer-controlled loading testThe system developed drives a specimen in the direction to the design point predicted from information obtained from a simultaneous loading test.This system evaluates the constitution and the value of limit state function from actual inelastic structural behaviors.An identical frame model was tested also by pseudo dynamic technique under an earthquake, and the failure mode observed in the on-line test was found similar to the result of hybrid design point search.

开发了性能评估系统并将其应用于两层钢制框架模型，其中将一阶可靠性方法中的设计点搜索与计算机控制的加载测试结合使用，该系统开发的系统将标本朝向信息预测的设计点的方向驱动从同时的加载测试中获得。该系统评估了从实际非弹性结构行为中的构成和极限状态函数的值。同样，在地震下通过伪动态技术测试了相同的框架模型，并且在网上观察到的故障模式发现测试类似于混合设计点搜索的结果。
