Dynamic Characteristics And Seismic Response Analysis Of Frame-Supported Multi-Ribbed Slab Structure

Multi-ribbed composite structure is a kind of energy saving, and good architecturalstructure seismic performance of the new system. frame-supported multi-ribbed slab structureis a means of large space the bottom adoption structure frame aseismic walls, and topmulti-ribbed composite structure by the housing construction. This structure easy realizebottom big space structure adjustment, and reduce the vertical stiffness of the earthquakeeffect damage, improving the building integrally anti-seismic performance。oneself to thestructure dynamic properties and seismic response analysis, which have done the followingseveral aspects of work：1. According to the principle of multi-ribbed composite force, In the composite differentmaterial constitutive relationship characteristics, and Proposed multi-ribbed composite forcomposite elastic plate equivalent mechanical model has been used to calculate the wholestructure, and the elastic stage of dynamic properties and seismic response performance。Byusing equivalent major position changeless, respect the layout structure of equal, andresistance to the lateral stiffness unchanged three principles.2. By ANSYS for frame-supported multi-ribbed slab structure a simplified model,dynamic analysis mode：tructure of the natural vibration period, the vibration frequency andstructure modal shape. Putting the structural dynamic characteristics and frame structure,shear wall structure was analyzed.3. Through a simplified model multi-ribbed composite of frame structure of thetime-history analysis, elastic waves, get their input different seismic response characteristics,and with the frame structure and shear wall structure is analyzed, the structural anti-seismicdesign provides the basis.4. In the earthquake effect, when the damping ratio changes, research the multi-ribbedcomposite structure frame teams in EL-Centro wave and Taft wave-the maximumdisplacement, under the action of displacements, the change rule of maximum acceleration.Shock for the structure optimization provides a technical measures.
