High Rise Steel Frame With Composite Deep Beam Structure Elasto-plastic Time History Analysis

Composite deep beams are composed with steel plate and concrete slab which connectedby high strength friction grip bolt. Composite deep beams have the same placement withshear walls in frame structure. By changing width of the deep beam, we could have differentresistance to lateral displacement stiffness to meet the requirements of two endpoints and canachieve a wide range of stiffness gradient amplitude modulation. By using different steel andconcrete, we could achieve different strength, ductility and energy dissipation capacities.Lateral precast reinforced concrete plate can stop buckling of steel plate. Steel deep beamsinstalled without stiffening rib. Lateral precast reinforced concrete plate and steel plate areconnected with bolts. Steel plate bears the lateral loads while reinforced concrete platedoesn’t bear any lateral loads. The reinforced concrete plate provides fire protection to steelplate. In addition, Composite deep beams are flexible layout and they are easy to the aisle andwindow layout. They can be used to the new structure as well as structural reinforcement. Sothey have theoretical research value and broad application foreground.Within the framework of this article through the steel composite deep beam finiteelement analysis and comparison of test results, prove the feasibility of finite elementanalysis. And then using finite element software ANSYS composite deep beam with a11-story steel frame structure, composite deep beam with different height-span ratio of8degrees respectively under strong seismic Elasto-plastic time-history analysis. Has beenfound that tall steel frame combinations deep beam structure can significantly increase thelateral stiffness of the structure, reducing the layer displacement, inter-high and reduce themagnitude and combination of deep beams than have a direct relationship and deep beamsbefore The steel framework for yield, able to absorb the seismic energy, energy dissipationcapacity. Through a combination of deep beams and steel frame stiffness distribution analysis,combined with the stiffness of high-rise frame-shear wall structure on structure definition ofcharacteristic values, senior composite deep beam of steel frame structures in the combinationof deep beams and steel frame stiffness distribution requirements, hoping to get the actualvalidation of the project. Finally, another combination of deep beams with different layout ofthe location of comparison, obtained using the same materials, deep beams, the combinationof different cross-ratio distortion has little effect on the structure of the whole, can not affectthe construction function under the premise of the combination deep beam arrangement to be adjusted.
