摘要: 本文对钢筋砼构件有限元分析提出了一种裂缝模拟的新方法,该方法同时具有离散裂缝法和分布裂缝法的优点,即能够在自动追踪裂缝开展的同时,求得裂缝的位置、裂缝宽度及裂缝的邻域应力分布,而不需对网格进行人工改造。计算结果表明,文本方法具有较高的精度。

Abstract: In this paper,the new method of F.E.M.is studied.The method can be used to trace the propagation of concrete cracking automatically,and at the same time,the position and the width of crack can be calculated.This method has all the advantages of discrete cracking method and smeared cracking method.The method in this paper can be used for the nonlinear analysis of reinforced concrete structure.

Key words: reinforced concrete, crack, finite element, regeneration
