Based on structures with a typical configuration but different stories as well as 80 suitable seismic records, the statistical amplifying factors for estimating the elastoplastic displacements of braced and unbraced steel building frames subjected to severe earthquakes have been obtained through a great number of numerical calculations.

本文在合理地选取丰富的地震记录及典型的结构形式的基础上，通过大量计算，统计得出了有支撑和无支撑钢框架结构在罕遇地震下弹塑性位移增大系数，以此提出了抗震设计时进行罕遇地震下多高层建筑钢结构弹塑性位移验算时的实用计算数表。

As compared with other heat preservation materials, XPS Extruded Board has a number of advantages when it is used in formed steel roof heat preservation structures:It makes the steel roof structure more durable thanks to its durability; it prevents cold-bridge of steel roof structure and guarantees against dewing and weeping inside buildings; it meets the requirements of load of different structures and execution of works for its high pressure strength; it meets the requirements of different environments and is suitable for factory buildings with high cleanness requirements for it is cleam and does not produce any dust thanks to its compactness of texture.

和其它的保温材料相比，挤塑板用于压型钢板屋面保温构造有着诸多优点：挤塑板的持久性使钢结构屋面持久耐用挤塑板用于钢结构屋面可以避免冷桥发生，保证建筑物内部不结露不滴水；挤塑板的抗压强度可适应各种结构及施工的荷载要求；挤塑板材质紧密、洁净而不产生粉尘，能适应各种环境的要求，亦适合净度要求高的厂房

This report is to generate a set of earthquake response data of bench-mark model of a five-story steel structure though a shaking table test. Test data is issuable in the data base on web site of NCREE and will be provided for structural system identification research.
