摘要
波形钢板桥梁为填埋式结构,活载计算类似于拱桥和涵洞,却又不尽相同。为探索波形钢板结构在活载作用下的内力计算,参考拱桥和涵洞的计算原理对波纹钢板活载计算方法进行总结和归纳,并通过有限元数值分析对结构的弯矩影响线进行绘制。得出波形钢板结构活载计算公式及施工过程中活载作用下的弯矩计算方法。
corrugated steel bridge is a landfill arch bridge and culvert, but they are not the same. type structure, live load calculation is similar to To explore the influence of live load and internal force calculation of the corrugated steel structure, this paper references the calculation principle of arch bridge and culvert. The calculation principle of the corrugated steel structure live load calculation are summarized and inducted. Through the finite element numerical analysis to the structure, bending mo- ment influence line is draw. Corrugated steel structure live load calculation formula and the bending mo- ment calculation method under construction process are summarized.
