钢栈桥混凝土面板轮压荷载分布宽度计算方法比较研究

Comparative Study on Calculation Methods of Wheel Load Distribution Width of Steel Trestle Concrete Panel

钢栈桥等临时工程没有相对应的设计规范,实际工程往往都是参照临时工程服务的主体工程设计规范。钢栈桥混凝土面板的计算关键是确定面板在集中力荷载作用下的荷载分布宽度。不同行业规范关于此项的规定不统一,计算结果也不尽相同,针对荷载分布宽度对各种计算方法进行综合对比分析,并结合有限元分析找出最适合钢栈桥特点的计算方法。

No corresponding design specification is used for temporary projects of steel trestle and so on,and the design specifications of the main projects served for temporary projects are generally referenced in the actual projects.The calculation of steel trestle concrete panel is mainly to determine the load distribution width of the panel under the concentrated load.The provisions of different codes of practice on this item are not unified,and the calculation results are not the same.Various calculation methods are comprehensively compared and analyzed according to the load distribution width,and the calculation method most suitable for the characteristics of steel trestle is found out in combination with the finite element analysis.
