Experiment And Seismi Behaviour Analysis Of RC Frames With Special-Shaped Columns

Along with the development of city construction, appeared a lot of new buildings structure form, R. C, frame structure with special-shaped column is one of them, the structure's form gets the expansion with apply in our country many cities with its advantage of not appearing column edges indoors, being easy to arrange furniture, extends effective areas of the room. Because of good architectural function, R.C. frame structure with special-shaped columns has got relatively extensive application in the recent years. However, as a kind of comparatively new structural system, it has never experienced the test of earthquake. The evaluation method and research of the analysis of its nonlinear analysis deformation and the anti-seismic performance has shortages under large earthquake for this kind of structure.In this article, by the method of tests and theoretical analysis, we research the anti-seismic performance of the concrete structure., witch are mentioned as follows.(1) It is shown that the seismic behaviour of this kind of frame is excellent. In terms of assuring that the joints of beam-column are not destroyed, the RC frames with special-shaped columns are the typical structure of strong columns and weak beams.(2) According to the phenomenon of the experiments, we analyses the strain of the structure nodes, and analyses the bearing of the shearing force of the wings of the nodes by the formulation in the norm.(3) Finally we look in to the distance of the special-shaped column concrete structure according to current situation.
