  The New York Times Building, currently under construction in New York City,is a study of balance and compromise. The vision of The New York Times to create a build ing ahead of the times was balanced by the goals of real estate developer Forest City Ratnerto develop an economically efficient building to maximize their leasable space on the upper floors. The innovative European-style architectural design of architect Renzo Piano Building Workshop was blended with the understanding of local building code and practice by NewYork architect Fox/Fowle Architects. One of the principal architectural features of the building, the expression of exterior steel,involved the compromise of aesthetic appearance, structural adequacy, and fabrication and erection practicality. The duality of each aspect of the building design from the ownership and design team partnerships to the overall balance between innovation and efficiency provided numerous engineering design challen-ges. This paper will outline some of these challenges, focusing on those driven by aesthetic, erection, and fabrication considerations of the exterior steel.

在过去十多年,FRP复合材料以其高强、轻质和耐锈蚀等独特的优点成为了土木工程中的新一代结构材料。FRP复合材料在混凝土结构中的应用尤其广泛,不仅被用于对现有混凝土结构的加固,也被用于新建混凝土结构中;后者包括FRP筋混凝土结构以及结合FRP型材和混凝土的FRP-混凝土组合结构(如FRP管混凝土柱)。近年来,FRP在钢结构中的应用也得到了应有的重视。由于FRP和钢材都是承受拉应力较为理想的材料,FR

本文介绍了双重弯剪型抗侧力体系弹性稳定的一个解析解。对于同时承受水平力的弹塑性体系,本文将压弯杆弹塑性失稳的Jezek模型进行拓展,引入模拟框架的摇摆柱与之并联,考虑初始侧移,引入水平力,得到了对弯曲型支撑的刚度要求的近似解析解,从简单到复杂,逐个分析不同受力下对支撑柱的截面刚度要求。通过这个拓展的弹塑性双重抗侧力模型,本文为正确理解和掌握高层钢结构的稳定性设计方法提供了思路。
为了研究冷弯薄壁卷边槽钢组合工字梁的承载力性能,对三种截面形式共计9根卷边槽钢组合工字梁进行了破坏性试验研究,然后建立有限元分析方法对试件进行模拟分析,有限元计算结果与试验结果吻合良好,验证了本文有限元方法的正确性。接着采用有限元方法对冷弯薄壁卷边槽钢组合工字梁进行大量的参数分析,钢种和受压翼缘宽厚比对受压翼缘有效宽厚比的影响较大,梁的长度、腹板高厚比与板件厚度对梁受压翼缘有效宽厚比的影响小。最后
