Recent experience in Japan, Mexico, and elsewhere shows that substantial damage, even total collapse, can occur to steel buildings. This project studies the effects of several recently recognized factors on the seismic performance of steel frame systems. These are: interaction of multicomponent ground motions, P-delta effect, and the effect of low ductility members. The study makes use of the established analytical capabilities in seismic analysis of buildings subjected to interacting ground motions at the University of Missouri-Rolla, and the extensive research experience in steel building structures at Lehigh University. The collaboration should provide a unique opportunity to develop an improved understanding of the seismic performance of tall steel buildings and more reliable methods of evaluating safety of such structures. The results would be useful for practicing engineers, academic researchers, and code writing bodies.

日本、墨西哥和其他地方最近的经验表明， 钢结构建筑物可能会受到损坏，甚至完全倒塌。 这个项目 研究了几个最近认识到的因素对 钢框架体系的抗震性能 这些是：相互作用 多分量地震动，P-δ效应，以及低 延性构件 该研究利用了现有的分析能力， 受相互作用地面运动影响的建筑物的地震分析. 密苏里大学罗拉分校，以及丰富的研究经验 在利哈伊大学研究钢结构建筑。 协作 应该提供一个独特的机会， 高层钢结构建筑的抗震性能更加可靠 评估这些结构的安全性的方法。 研究结果将对工程实践、学术研究、 研究人员和代码编写机构。
