有限元法在钢混结构非线性分析中的应用

有限元法在钢筋混凝土结构非线性分析中,充分体现了它"全过程仿真"的特点,和传统的线弹性分析及常规计算模型相比,它的适应性更强,力学概念更加明确,分析过程更加精确。由于钢筋混凝土结构的特点及其非线性理论的发展和完善,使有限元方法在解决混凝土的破坏准则、本构模型、钢筋与混凝土之间的关系模型、裂缝问题以及过程分析的计算机程序实现等问题中得到广泛应用,具有广阔的发展前景。

The Application of Definite Element Method in the Nonlinear Analysis of Reinforced Concrete Structure

In the nonlinear analysis of reinforced concrete structure, definite element method man ifests better its feature of ＂simulation in the whole process＂ and compared with the traditional linear analysis and common calculation model it is more adaptable, its mechanic concept is clearer and analysis is more accurate. Because of the features of reinforced concrete structure and nonlinear theory＇s development and perfection, definite element methods has been widely applied in many aspects of reinforced concrete structure and has great prospects.
