无梁板桥的实用计算

Applicatial Calculation for Pilz bridge

本文用有限元法编制了无梁板桥实用计算程序，程序可用来模拟任何形状元梁板桥上部结构的力学性能；处理复杂的约束边界条件；模拟柱对板的作用，以求得柱顶反力，还可获得柱身截面的内力；并可进行板截面配筋计算和强度验算。程序计算和试验结果符合较好。

his paper provides an applicatial program for calculating pilz bridge by using finite element method. The program can imitate the mechanical characteristics of the superstructure of pilz bridge which has arbitrary shape and complicated suppport condition.Furthmore,the program can simulate the action of column on the plate, give the reaction on the top of column and calculate the internal force of column sections. The program can also gain the sum toral of reinforcement and check strength of plate section automatically.Both the computing and the testing results are most coincide.
