英语翻译
Recent demands for improvements and upgrades of infrastructure,which includes,among other public facilities,the highway system and bridges,have increased the number of structural engineers employed by highway departments and consulting firms.Graduates with advanced degrees in structural engineering in the areas of experimental works,computing and information technology,computer-aided design and engineering,interactive graphics,and knowledge-based expert systems are in great demand by consulting firms,private industry,government and national laboratories,and educational institutions.The rapid advancement in computer hardware,particularly in the computing and graphics performance of personal computers and workstations,is making future structural engineering more and more oriented toward computer-aided engineering.Increased computational power will also make hitherto unrealized approaches feasible.For example,this will make the rigorous consideration of the life-cycle analysis and performance-based assessment of large structural systems feasible and practical.Advanced analysis and high-performance computing in structural engineering are now subjects of intense research interest.Good progress has been made,but much more remains to be done.

最近,对于包括其它公共设施,高速路系统设施和桥梁的基础设施的改善与升级的要求,使高速路部门与咨询公司雇佣的结构工程师数量上升.咨询公司、私营工厂、政府和国家实验室及教育研究所对有着高等学历的实验工作领域的结构工程、计算机辅助设计与工程,互动绘图专业的毕业生,以及知识丰富的专家系统,有很大的需求.
计算机硬件,尤其是个人电脑和工作站的计算及绘图能力的快速增长,正使得未来的结构工程越来越倾向于计算机辅助工程.增加的计算机性能也将使目前还未被发现的方法变得可能.比如,这将使生命周期分析的想法和基于性能的大型结构系统的评估变为现实.结构工程中高级的分析和高性能的计算现在成为大量研究的对象.尽管有了很好的进步,但仍有许多要做的.
