基于中国美国欧盟标准的圆形灌注桩配筋计算系统开发研究

Research on calculation system development of circular cast-in-place pile from China-USA-EU Code

运用微分原理并基于Mathcad分析平台,对中国标准、欧盟标准和美国标准钢筋混凝土圆柱结构的极限承载力分别进行程序编写,得到圆形截面的承载力曲线进行灌注桩设计,形成一套圆形灌注桩设计计算系统,达到计算标准化的目的。该计算系统采用图形一体化,输入和输出直观、易懂,并且采用微分手段可得出结构的承载能力曲线及灌注桩配筋标准化文件,更适合设计人员根据需要进行选择使用。

Using differential theory and based on Mathcad analysis platform,the program of ultimate bearing capacity calculation of the reinforced concrete cylinder structure had been written by China-USA-EU code,respectively.Structural bearing capacity curve of circular cross section was got for designing cast-in-place pile.A set of calculation system of circular cast-in-place pile design is formed,achieving the purpose of computing standardization.The calculation system realizes graphic integration.Input and output are intuitive and simple.Differential method is adopted that can obtain structural ultimate bearing capacity curve and reinforcement standardized documents of cast-in-place pile.This calculation method is more suitable for designer to use according to the need of design.
