The Seismic Finite Element Analysis On Frame In Different Damper Model

Our country is located in the Pacific Ocean , the Asia earthquake zone , geologicstructure is complicated, is that a earthquake sends out the country muchly. With economy rapidly development , various different type , the complicated building of structure spring up unceasingly. This has brought forward higher request to structure aseismatic design right away. All the countries in the world , structure design engineers and technicians have suggested many theory that some have already got application and have got certain effect in actual project. The energy-dissipation damper equipped in weak-layer of framed structure application have been done in the all along theory , experiment and the finite element analysis in actual project.First, the thesis has obtained hysteretic curve and function parameter of the friction damper (FRD) and viscpelactic damper (VED) with the changing of extitement on dynamical experiment basis.Second , the finite element models of the three dampers and the combined elemet stiffness matrixare constructed. According to above damper-based job mechanism, the finite element analysis have been in progress interposing the frame structure equipped with the damper braced system. Result is indicated, the friction device does not slide under minute earthquake, thus the control effort of F-VED correspends with VED, and the action of FRD is not obvious. Under disastrous earthquake, the friction device begins to slide, so the control effort of F-VED is the best.Final, the dynamical finite analysis are carrisd on to obtain the seismic respense of 10-floor R.C frame with the three EDD-bracing system on the above-mentioned experiment and the theoretical analysis basis in this paper. And contrast on them have carried out, result comparatively is identical with test result , this is that actual structure interposes the damper aseismatic design having provided the beneficial reference right away.
