Research For Details Measures Of Damper With The Middle Wall Installed

This thesis mainly introduces the viscous dampers and mild steel shear plate damper of existing details measures in building structure, lists the existing damper and construction measures of the connection between the components of what, and in view of the existing structural measures for further research. Briefly introduced the viscous dampers and mild steel damper related research status at home and abroad and the corresponding dynamic model of damper, and institute of selecting dynamic model in this thesis. Introduces the finite element software and the corresponding analysis method.Research on mild steel shear plate damper under the action of earthquake energy dissipation, the shear plate was deduced under horizontal load of the related parameters, such as yield strength, the yield displacement, maximum shear and maximum displacement. By establishing the model of two kinds of different structure, making the horizontal loading under the action of sine wave, researching for the clipboard curve of energy consumption and the related parameters,finally comparing the theoretical values is derived and analogue data. The results show that Simulating different connection plate have small influence on energy consumption and parameters; Theoretical values and analogue data of yield force and maximum shear is large, and the yield displacement and the maximum displacement is smaller.Two description of energy dissipation damper parameters is proposed:utilization of story displacement and shear ratio.Under the action of the earthquake, At the same time,single frame structure in mild steel shear plate damper is simulated for finite element.By comparison with several kinds of model parameters are:only a Link connecting unit and diagonal bracing substitute beam model can approximate the structure of the mild steel shear plate damper model (d model of section 4.3).Through the single frame structure model is established to study the four different details measures of cantilever wall, with four model under the condition of the damper output is the same, the structural deformation, shear force, shear ratio, story displacement, the inter-layer displacement angle, utilization rate of story displacement, the expending displacement of cantilever wall, the maximum shear force and bending moment of beam and column are compared, the analysis of the cantilever wall in the middle and connected to the viscous dampers (a model of section 5.2) for structure is better than the other three kinds of structure of energy consumption.Introducing the structure model of suspension components of three kinds of different ways of connection. When the damper output 300 KN,500 KN and 800 KN, in view of Q235, Q345 steel, calculating the stability of the different sectional dimension of steel shotcrete, and optimizing the design of the sectional dimension. Listing the three kinds of model of the damper output is not at the same time, using the designing table of sectional dimension of steel shotcrete (appendix B) facilitating application of the design and construction personnel.For the three models in section 6.2, as a control condition of utilization of story displacement and stress of steel element, and what kind of type and sectional dimension of steel is good for structural damping is determined.
