Research On Mechanical Behavior Of Reinforced Concrete Column-steel Beams Moment Joints Based On Different Structural Form

Composite RCS moment frames integrate reinforced concrete columns withstructural steel beams, providing several advantages over conventional steel or concretemoment resisting frames. Columns have the advantage of good compressive behavior.Their large rigidity, good durability, and fire proof property. result in steel saving,reduced costs and increased stability of structure. Beams have the advantage of higherstrength, lighter weight and higher construction speed, resulting in reduced structuraldead weight, smaller member sizes and building height, increased effective spaces, andreduced foundation costs. composite frame, composed of reinforced concrete columnand steel beam, is a newly low cost and highly efficient structure for its economicalutilization on the characteristic of steel and reinforced concrete.The key of reinforced concrete column-steel beam （RCS） composite frame liesin the research of composite structure and design of nodes, however the research ofRCS node has just started in our country.Lake of reasearch on the mechanical propertiesfor RCS node,Especially the mechanical properties for RCS node on the differentstructure form,Existing structure form are various,Now,Lake of a kind of structure formconsiderd the comprehensive factors and resonable load,So,In this article by the methodof using ABAQUS nonlinear finite element establish the finite element model ofconcrete column-steel beam（RCS）of steel-node, Through the analysis of the example,Adjust calculation parameters that make the finite element calculation result fit for thetest results,Verify the applicability of ABAQUS software for the general structuresystem, Design contrast specimens of concrete column-steel beam（RCS）of steel-node,On the basis of comparison specimens design the different structural form of mechanics performance, Takes Mechanics analysis of the whole process to these components, Thecontrast between the different structural form analysis, The comparison of the differentdefinitions of the model, The contrast between the different parameters analysis, etc,The contrast between finite element calculation results of Shear-carrying capacitydesign value and The United States code of RCS nodes on the shear capacity ofcalculated formula of shear-carrying capacity, Analysis of the influence of differentstructural formula and the reflection of the formula, finally synthesize the researchresults of the integrated predecessors put forward a more reasonable joint structure form,And using this newinformation, design models and calculation eduations forinterior andexterior connections are established, which provide theoretical basis for designexperiment research and construction of RCS joints.
