This article is probed into on the issue that the influence of border concealed column toward shear wall stiffness. Charge example indicates finite element that this text set up calculate model is acceptable. It is used the finite element method basic theory to compile finite element analysis procedure with four points rectangles unit to solve this problem. It can calculate the shear wall with concealed column’s displacement under the wind load to check the result it whether can be satisfied the design request. Using this procedure, this article carries on the finite element modeling analysis on a ten-floor building shear wall structure system. The procedure’s result and the software of ANSYS’s result tallies well, and it also be compared with the simplification computation’s result.

Coupling beam, the first line resisting earthquake, is directly related to the overall performance of the shear wall structure. Using the large general finite element analysis software ANSYS, the coupling beam span-depth ratio is 2~3 different reinforcement scheme in finite element analysis. Analysis on the ductility performance of reinforced concrete coupling beams in shear wall structure in three fields: the concrete strength grade, the longitudinal reinforcement ratio and the stirrup ratio, provides a basis for the design of the structure and to provide a reference for similar studies.

The use of monitoring techniques during the operation of a building contributes to the study of the stress-strain state of both known and newly developed structural systems. The article discusses the effect of reducing the bending stiffness of reinforced concrete crossbars of high-rise buildings on the overall deformability, which can be monitored by changing the angles of rotation at characteristic points. For the introduction into the model of the calculation based on finite elements of the physical parameters of the stiffness of reinforced concrete bending elements, the function of the change in the shoulder of a pair of forces in the section during the opening of normal cracks is given. Empirical data on changes in the stress unevenness coefficient along the length of the reinforcing bar are used. The calculation is based on the diagrammatic method. The data on the accumulated experience of measuring the angles of rotation of a building with automatic monitoring of buildings are presented. Using the finite element method, the systems were simulated with a decrease in stiffness to 0.4 from the initial one. It is shown that it is possible to select a range of sensors - angle meters - inclinometers. It has been determined that the angle of rotation can be changed up to 1.6 times. The corresponding ranges are defined for two types of frameworks: frame and frame-braced. The nature of the change in the overall stiffness of the building frame as a result of reducing the stiffness of the crossbars is shown. Calculation models based on the finite element method determined the deformation limits of the entire frame as a whole.

This article research frame supported shear wall structure Beam-type Transfer layer at the supporting wall (across full) shape and the supporting column two structure forms, in the same form of vertical uniformly distributed load, the stress distribution variation trend and characteristics of the analyzed and discussed. Using large-scale finite element analysis software ANSYS to two different Beam-type Transfer structure of the nonlinear simulation analysis, combined with the stress nephogram of X to the analysis of two kinds of structure forms of the transfer beam and upper wall and the frame work characteristics [. The results of the study show that: In terms of the vertical stress, wall shape across the full shear wall in the stress of the beam structure performance is better, Column will produce large stress in the beam. Shear wall and stress of the transfer beam work together to transform beam has a great influence.

In order to evaluate seismic reliability and vulnerability of the typical small high-rise shear wall buildings in Western China region, the sample finite element analytical small high-rise shear wall structure has been built in considering of fiber element model and fiber wall element model. Meantime stochastic response spectrum of accelerations with 5% damping ratio have being set up based on China Seismic Code as input seismic excitation, dynamic history analysis was being used to determine earthquake resistant capability of sample structures. Vulnerability curves of four performance levels are also be drawn after carefully analysis based PGA index.

The aim in this study is to numerically present some characteristic features of the rectangular finite element using the matrix displacement method and to show the utility of this element in plane stress problems compared to the finite element method. The paper consisted of three parts. In the first part, all of the finite element formulation steps from choosing the convenient coordinate system to creating element stiffness matrix are presented respectively. In the second part of the study, a static finite element analysis of the shear wall is also made by ANSYS Mechanical APDL. In the final part, the results (displacements, strains and stresses) obtained from the previous parts are compared with each other by the help of tables and graphics. The results show that this method is effective and preferable for the stress analysis of shell structures. Further studies should be conducted in order to indicate the efficiency of the matrix displacement method for the solution of different types of plane stress problems using different finite elements.

It shows that the experimental results fairly confirms to the calculated values, which indicates that this new structure has advantages as good architectural function, big effective space, high overall lateral stiffness, fine ductility, advanced seismic behavior, etc.. That is, the close agreement between the theoretical and experimental results indicates the proposed shear wall structure has wide applications.

Reinforced concrete eccentric frame-shear wall structure has been widely used in engineering. However, this structure is mainly used for high-rise structure, and it is difficult to obtain accurate earthquake response of structure through experimental study. Therefore, simulation software needs to be used for study on seismic performance of high-rise structures. This paper produces useful conclusions for the project through shaking table test and the simulation of seismic performance provided by ANSYS finite element analysis software.
