本文提出了一种计算模拟混凝土构件荷栽──位移全过程曲线的方法──刚度荷载法，并采用基于钝裂带模型（ＢＣＢＭ）的混凝土材料全量型本构关系和三线型应变软化为线，编制了相应的计算分析程序，对碾压混凝土三点弯曲梁、楔入劈拉、碾压混凝土拱坝诱导缝典型结构等构件进行了计算分析，得到了结构”的荷载一位移全过程曲线、碾压混凝土材料拉伸软化曲线参数等一些有意义的数据和结果。计算结果与试验结果及用虚拟裂纹模型计算的结果吻合较好。
In this paper, a new method for calculating the whole process of load-displacement curve of concrete-filled concrete is presented. The stiffness load method and the full-mass constitutive relation of concrete material based on the blunt cracked zone model (BCBM) Line, the corresponding calculation and analysis program has been compiled, and the components such as RCC 3D curved beam, wedge splitting and pulling, RCC arch dam typical structure and so on have been calculated and analyzed, and the structure "load-displacement whole process Curve, some parameters such as tensile softening curve of roller compacted concrete, and the results are in good agreement with the experimental results and calculated by the virtual crack model.
