Incremental method for computing curve - point 利于计算曲线点串的差分算法
4 . based on the theory - character parameter , this paper presents the theory equation for stress - stain complete curves of the rpc filled steel tube , it is founded that computed curves are in good agreement with the tested one , and it can be applied for the all course analysis of the rpc filled steel tube 4 、基于上述圆钢管rpc轴压柱的理论特征参数,推导建立了圆钢管rpc轴压柱应力应变全曲线理论方程,该方程理论曲线与试验曲线相当吻合,可用于圆钢管rpc构件的全过程分析。
