program can analyze the multi-girder curved bridge, by using the diatropic distributing theory . it can calculate the dynamic programming loading, by using the combined influence . it can analyze the internal force under the action with the prestressed force, by using the equivalent load method 程序采用横向分布的实用计算理论来处理多主梁曲线梁桥的空间受力分析问题;采用组合影响线来对曲线梁桥进行动态规划加载;采用等代荷载法对曲线梁在预应力作用下的结构内力进行分析。
on the base of fatigue loading spectrum achievements, combining the characteristics of large-span grid structure with hanging cranes and the using-requirement on fatigue loading spectrum of grid structure with hanging cranes, this paper has firstly put forward the theoretic method for constructing fatigue loading spectrum of grid structure with hanging cranes, organized the relevant program-- gjfls . and elementally established the program loading spectrum 在继承疲劳载荷谱已有成果的基础上,本文结合网架设置悬挂吊车的特点以及网架疲劳载荷谱的使用要求,首次提出了网架疲劳载荷谱编制的理论方法,并编制了相应的程序(gjfls),初步建立了网架程序载荷谱。
