混凝土徐变试验计算及绘图程序

A Program to Numerically Analyze and Draw the Result of Concrete Creep Test

本文提供一个用于计算混凝土徐变试验的FORTRAN程序。该程序能够计算出徐变试验混凝土不同龄期的弹模值、不同龄期各持荷时间的徐变度值、松驰系数值,并能用宽行打印机在半对数坐标架下绘制出高分辨率的龄期弹模曲线、瞬时弹模变形曲线、徐变度曲线、松驰系数曲线。

This paper provides a FORTRAN program to numerically analyze and draw the results of concrete creep test. The program not only can be used to compute the values of elastic modulus coefficients, creep rates and relaxation factors of concrete during every ages in its creep test, but also can draw highprecision concrete elastic modulus coefficient curves, instantaneous elastic defor mation curves, creep rate-time curves and relaxation factor curves with a wideline printer. It has been found by use of this program in computation and drawing results of concrete creep test in Tonggu Datuan Dam, the work loads of anlyzing experimental data may be largely reduced and a satisfactory result can be gotten with the program.
