双箱单室钢箱梁桥设计

Design of double box single chamber steel box girder bridge

钢桥是大跨度桥梁的主要形式。以山东XX双箱单室钢桥为例,详细介绍钢桥总体优化设计,通过桥梁博士建立有限元模型,计算结果表明拉/压弯构件弯曲正应力验算、剪应力验算、折算应力验算、挠度验算、疲劳验算均满足要求。

Steel bridge is the main form of long-span bridge.Taking a double-box single-chamber steel bridge in Shandong as an example,the overall optimization design of the steel bridge is introduced in detail,and the finite element model is established by the bridge doctor.The calculation results show that tension/compression bending member bending normal stress check calculation,shear stress check calculation,converted stress check calculation,deflection check calculation,fatigue check calculation all meet the requirements.
