High-rise Building Frame-Shear Wall Construction Process By Considering The Performance Of Force

High-rise building is the product of social needs and technological progress. With the continuous development of construction technology and the construction schedule, it becomes more and more important to analyze the construction process of high-rise building. The high-rise building in construction phase is a time-varying structural system, and compared with the "have been completed buildings", the difference is that the geometry, border and physical conditions of structure are change with time, and the stiffness matrix, mass matrix etc are the function of time. Compared with the traditional structural analysis model, the model of time-varying structure system can reflect the internal force distribution of structure well.Currently, when analyzing and designing high-rise buildings, mostly use "the have been completed buildings" as the study object, without considering the co-nstruction process of high-rise building and the feature of internal force and def-ormation gradually accumulate and redistribution, so it may make errors even se-curity risk.Therefore, studying on the traditional "a load calculation method" and "con-struction process simulation method of load calculation" have difference in the design, studying internal force and deformation gradually accumulate and redistri-bution are very useful to the design and construction of high-rise building. This study conducted the following:1,To the system of high-rise building, this paper discussed the principles a nd methods of simulation, established the mechanical model of simulation of co- nstruction process of high-rise building.2,Using large-scale finite element analysis software, simulate the constructio n process of high-rise building by the method of construction process simulation method of load calculation.3,The bending moment, shear and axial forces of beams, columns, shear walls and board are analyzed between "a load calculation method" and "constr-uction process simulation method of load calculation"Based on the construction order, the structure is divided into several sub-str uctures, and internal forces of structure are calculated. The results show that the method of "construction process simulation method of load calculation consider more factors and can reflect the actual stress state of high-rise building well, so the results are Safer. It has theoretical and practical significance to assure the re-liability and security of the whole process of structure construction.
