基于性能设计理念下的公路桥梁结构设计研究

Research on highway bridge structure design based on performance design concept

公路桥梁是一个国家交通运输的主要形式之一,对国家经济发展、社会进步有重要作用,桥梁的规模水平彰显国家经济基础和技术能力。基于此,本文先提出基于性能设计理念下公路桥梁结构设计的标准框架,再指出桥梁性能设计的根本原则,并从几方面对公路桥梁的结构性能展开分析,最后给出了相对应的性能目标,希望对未来公路桥梁结构设计有一定的借鉴意义。

Highway bridge is one of the main forms of national transportation,which plays an important role in national economic development and social progress. Based on this,in the paper,based on the concept of performance design for structure design of highway bridges standard framework.Then it points out the fundamental principles of performance design of bridge,and from several aspects of highway bridge structure performance analysis,finally gives the corresponding performance goals,and I hope to future structural design of highway bridges have certain reference significance.
