摘要
很多情况下混凝土结构是带裂缝工作的,在其开裂过程中,原有的部分裂缝可能不同程度地重新闭合,并有一些新的裂缝产生。笔者基于非线性有限元理论,模拟了裂缝张开和闭合过程中剪切传递系数的取值对混凝土梁断裂过程及强度的影响,以期为混凝土结构设计打下基础。
In many cases, concrete structures work with cracks, in its cracking process, some original cracks may be reclosed in varying degrees, and some new cracks would be produced. Based on the nonlinear finite element theory, the impact of crack＇s shear transferring coefficient value on the fracture process and strength in the process of opening and closing, with a view to laying a foundation for the design of concrete.
