正交异性钢箱梁桥面第二体系结构优化设计
Structural Optimum Design of the Second System of Orth otropic Steel Bridge
摘要
Abstract
Based on analysis of mechnanics, the modal of pavement system of orthot ropic steel box girder bridge is established. The mechanical behaviour of orthot ropic steel box girder bridge is researched by FEM. The structural optimum desig n for the second system of orthotropic steel bridge considering deflection, stre ss and strain is discussed from the aspect of thickness, module of the pavement, distance of the transverse beam, the thickness of steel deck and the stiffness of trapezoidal rib, etc. The rational numerical demarcation of each parameter of the orthotropic steel bridge deck is offered.It can be seen that the result of d esign is reasonable which will provide theoretical basis for large-span steel -box-girder design after comparing the results of this paper with that of othe r similar bridges.关键词
