Study Of Deformation Analysis And Deformation Control For The Jacking Rectification On Brick-concrete Structure

At present,a lot of brick-concrete structure due to various reasons have a differential settlement and tilt, In order to restore its normal function, reduce unnecessary losses, reinforcement should be done. Therefore, the theory and technology of brick structure in reinforcement become one of the important issues in today's structural engineering research.In this paper, taking brick-concrete structure house inclining for example, using numerical simulation and verification in practice, research on brick-concrete structure housing the top of the rectification process of the structure of the law of force and deformation have been four areas of research :â‘ established brick-concrete structure jacking rectification of non-linear finite element analysis model, by comparison of the actual works to verify the feasibility of the model;â‘¡a brick-concrete structure in the top or the top or rectification, the top or face, loading points, loading capacity of key technologies such as methods to determine;â‘¢by numerical simulation analysis of the structure of the top or side of the distribution of stress and deformation, the surface used at the top or a short load steel support measures to a greater distance between load points to raise, and to make top-up operation has been simplified rectification, so that the construction period and reduced funding;â‘£brick-concrete structure in accordance with the characteristics and structural deformation of the coordination, a top-up the process of deformation control points and anti-back shen measures carried out by the project to verify.Through the Project to verify the above-mentioned study to prove that the text of the masonry structure on the top or rectification of the deformation and deformation analysis of the feasibility of control methods for brick-concrete structure housing the top or rectification provide a reference design and construction.
