Studies On The Basic Properties Of Hybrid Frame Of Steel Reinforced Concrete (SRC) Column-steel Beam

Hybrid frame of Steel Reinforced Concrete (SRC) column - steel beam is a new structural system of steel-concrete composite structure. In comparison to common reinforced concrete frames, hybrid frame of SRC column - steel beam has better earthquake-resistant behavior and structural function, and this structural system can effectively and reasonably realize the coordination of architectural, structure and cost for high-rise residential buildings of small type and office buildings, and it has also been applied widely in large span structures, High-Rise Building and Super High-rise Building, so this structural system has extensive application prospect.This paper adopts some large scale general finite element analysis softwares including ETABS, SAP2000 and MIDAS to perform simulation analysis such as model analysis, mode superposition response spectrum analysis, time-history analysis and nonlinear static analysis (Push-over analysis) based on these parameters such as axial compression ratio of SRC column, form of steel of SRC column, steel ratio of SRC column, reinforcement ratio of SRC column, concrete strength grade of SRC column and linear stiffness ratio of beam to column. The main study contents include deformation capacity, ductility and energy dissipation capacity of hybrid frame of Steel Reinforced Concrete column (SRC) column - steel beam, and the results of the analysis are mainly presented by tables and figs. There is a innovative study method in this paper is that to analyse the stiffness and ductility of hybrid frame of Steel Reinforced Concrete (SRC) column - steel beam by means of story ratation under minor earthquake action and large earthquake action.The analytic model which this paper adopted is a hybrid frame of SRC column - steel beam with ten stories. The analytic model has five spans in X axial direction and three spans in Y axial direction , and every span length is six meters.The results of the analytical studies demonstrate that these three large scale general finite element analysis softwares (ETABS, SAP2000 and MIDAS) have preferably coherence on the calculation of analytic model, and the results of the elastic analysis have intrinsic coherence with the Elastic-Plastic analysis, and the results of the analytical studies are basically agreement with the previous experimental values and theoretical values. This paper also has some innovative study and study methods, and puts forward some conclusion for design.
