波形钢腹板箱梁桥剪力键形式的优化设计

Optimization Design for Shear Connector of Box Girder Bridge with Corrugated Steel Web

随着我国高速公路建设的不断发展,一些新结构新工艺在国内得到了应用和推广,特别是波形钢腹板组合箱梁桥已成为国内科研、设计、施工、监控等部门的研究重点。但该类桥梁存在剪力键处应力集中的问题。鉴于此,在现有剪力键的基础上对其进行了优化设计,以消弱应力集中对钢-混凝土结构造成的不利影响。

With the continuous development of China′s highway construction,some of the new structure and technology has been applied and promoted.In particular,box girder bridge with corrugated steel web has become the research focus of research,design,construction,monitoring and other departments.But these bridges have the key issues that shear stress concentrates at the shear connector.Given this,the paper conducts optimization design based on existing shear connector to weaken the adverse effect of stress concentration on steel-concrete structure.
