局部位形约束生死单元法及其在施工力学分析中的应用
A method of element birth and death of local configuration constraint and its application in construction mechanics
摘要
Abstract
Based on the three positioning principles for installation in bridge engineering,the fourth positioning principle for installation which is suitable for the construction engineering is put forward.Based on the characteristics and applicability of a few existing analysis methods of construction mechanics for structure and according to the positioning principles of components of structure in actual projects,an improved nonlinear analysis method named element birth and death of local configuration constraint is put forward to solve the problem of death element’s ’floating’ in this paper.This method was applied in the mechanical emulation and analysis of the Heshi Stupa of Famen Temple during the construction process.The computation results by the improved method agreed with the measured values well in the project.This indicates that the improved method is an effective analysis method of construction mechanics for structure.关键词
