Construction Simulation Method of Pre-stressed Wheel Steel Structure
摘要
Abstract
With the development of construction technology,construction methods with rigid body rotation is making progress continuously,bringing challenges to construction simulation technology not only in simulating the construction process with a lot of members,but also in simulating the construction process with increased and moved members.This paper is based on the vertical rotation construction method of Beijing Great Wheel. According to the nonlinear finite element method,the expansion and modification method of the displacement matrix,load matrix and tangent stiffness matrix after rigid body rotation are proposed,providing theoretical ba-sis for new construction simulation method for construction process with rigid body rotation;Based on the mod-eling by step method,combined with the application of finite element software ANSYS,a new construction simulation method named as the coordinate rotation method based on modeling by step is proposed.The validi-ty of this method is verified by examples.关键词
