摘要:
为了在钢筋混凝土结构有限元分析模型中对裂缝进行描述,建立了基于网格自适应的有限元裂缝分析模型,可以比较直观地模拟裂缝的发生和开展过程; 同时引入随机模拟方法,采用蒙特卡罗(Monte Carlo)法处理与裂缝有关的参数。用该方法能够模拟钢筋混凝土结构裂缝出现位置和间距的随机性,而且能改进计算数据的后处理。对跨中受力的钢筋混凝土简支梁进行计算分析,所得裂缝分布和位移均与试验结果吻合良好。结果表明,用该方法对钢筋混凝土结构进行分析是合理的,也是可行的。
Abstract:
A new cracking model for finite element analysis of reinforced concrete structures was described. This model was set up based on mesh self-adaption and could simulate the crack development and continuation process for the failure analysis of reinforced concrete structures. Also, by using Monte Carlo methods with random variables related to crack development, it was found that the uncertainties of fracture position and distribution could be modeled. The post processings of finite element results were also improved. Finally, the computing result of a simply supported beams shows that the crack pattern and displacement of the beam are accordant with the experiment results. The result shows that the current method is rational and feasible.
