Abstract

Abstract: Theoretical analysis on interfacial slip of model beam with corrugated steel webs under various typical loads was conducted to know the anti-bending performance of the box girder with corrugated steel webs. Based on the assumption that the corrugated steel didn' t bear the longitudinal axis force and vertical bending moment , the cross-section of beam with corrugated steel webs were divided into four independently ideal elastomers , and the slip differential equations was established. By simulating the actual boundary conditions , the interface slip expression of composite beams model was deduced under the uniformly distributed load , inid-span concentrated load , and the two-point symmetrical load. The expression of additional curvature caused by slip distribution was also derived. The mathematical formula is used to express the interface slip of corrugated steel webs beam , which lays the foundation for the load studies of corrugated steel webs.

Key words: bridge engineering, corrugated steel webs, interface slip, bending performance, additional curvature

摘要： 为了解波形钢腹板箱梁的坚向抗弯性能，分析了波形钢腹板简支梁模型在各种基本荷载作用下的界面滑移状况。假定波形铜板不承受纵向轴力和坚向弯矩，把波形钢腹极梁截面划分为4个独立的理想、弹性体，建立了滑移微分方程;通过模拟实际的边界条件，推导出了组合梁模型在均布荷载、跨中集中荷载、两点对称加载作用下的界面滑移表达式，及滑移引起的简支梁附加由率表达式。以数学公式表达波形钢腹板梁的界面滑移，为波形钢腹板梁的承载力研究奠定了基础。
