In the last decades, computers have been widely used in the investigation of structural behaviour and failures.The revolution of computing speed sees an increased reliance of direct analysis for designing large-scale structural system.This paper reviews some of the principles related to the use of direct analysis for performance based design of steel and composite frames and discusses the issues that are essential for implementation in practice.Illustrative examples are given to show the benefits of using direct analysis for evaluating the overall performance of structural systems in terms of serviceability, ultimate strength under accidental design situations such as fire.

亮布是我国古老的传统文化,但是工艺极其复杂,但如今社会的发展促进了的文化的交流,使得一些传统文化被保护或被破坏.传统亮布耐摩擦色牢度和耐皂洗色牢度较差,导致该项传统工艺未能被纳入现代服饰的应用中.在本次研究中,运用了现代面料加工整理中使用的固色剂DC对传统亮布进行处理,比较了不同实验条件处理下的亮布耐摩擦牢度和耐皂洗色牢度,最终得出改善传统亮布色牢度的最佳可行性手段.
随着高分子材料工业的发展，纤维，树脂，橡胶等合成材料越来越多的用于化工，建筑，交通，电子等行业.但大部分的高分子材料均易燃烧，在很多应用领域中,为了防止火灾,需要在高分子材料中添加阻燃剂,在粘结剂中也是必须添加阻燃剂的。分析了近年来氢氧化镁阻燃剂在粘合剂材料的研究进展,介绍氢氧化镁阻燃剂的阻燃机理和制备方法,对氢氧化镁协同阻燃增效剂以及氢氧化镁的表面改性技术进行了简要的评价,对氢氧化镁阻燃剂在粘合
