| 中文摘要 | 施工过程"路径"和"时间"效应对施工及使用阶段结构力学状态影响的分析是目前亟待解决的施工力学问题.深入研究了考虑结构时变以及耦合几何非线性因素后单元生死技术模拟施工过程的基本原理,从数学和物理上揭示了单元"杀死"、"漂移"和"激活"的机理,探讨了耦合几何非线性因素后分步建模技术求解施工过程的基本原理,对这两种分析方法进行了比较.基于经典梁单元,采用FORTRAN语言编制了施工过程分析的有限元程序.算例分析表明,分析方法及所编制程序正确,是结构施工力学分析的有效方法.; Mechanical analysis of structures in the construction, in consideration of the "path" and "time" effect, is usually met in actual projects at present. Based on the state nonlinear finite element method, the principles of element's "death" , "floating" and "birth" for element birth and death technology are revealed, associated with the geometric nonlinear effect. Another simulation method, namely step-by-step model technology, is discussed. A finite element model simulating structural construction process is also presented, and a corresponding analysis program is produced by employing the FORTRAN programming language based on the classical beam element. |
