Analysis Impact Of Multi-ribbed Composite Panels For Framework Seismic Performance

Economical and suitable for reinforced concrete frame structures, building layout flexibility, size and other advantages, are widely used in offices,apartments, hospitals and other public, civil construction, is now widely used in China’s structure.But seismic performance of frame structures of a single, so enhancing the seismic performance of frame structure is essential, this paper is in the framework of multi-ribbed composite slab structure in the local layout, multiribbed composite wall instead of the conventional shear walls or anti-seismic reinforcement of steel braced frame structures, forming a new framework--of multi-ribbed composite slab structure system. Paper using theory analysis and numerical simulation phase combines of method, in early research of based Shang, focuses on on framework-key rib composite Board system of seismic performance, and hosted force calculation method, and framework--key rib composite Board system collaborative work performance, and construction process and the constructed measures, aspects for system of research, for framework-key rib composite Board system of actual engineering application provides design according to and the theory Guide. The main contents of the paper are:1.Timoshenko frame-shear theory research of multi-ribbed composite slab bending and shear deformation relationships between deformation and displacement using the structure of a classic continuum method system ofdifferential equations, provide the basis for the seismic design of the structure.2. Frame-based on Finite Element Method software ABAQUS Multi-ribbed structure model of composite panels, seismic, storey displacement, acceleration analysis model of variation, discussing frame-seismic performance of multiribbed compound wall structure.3. The analysis and modeling of the combined task group, is used to calculate the body natural vibration period of system properties, such as to determine the earthquake. Multi-ribbed composite wall compound the damage characteristics of wall construction methods are discussed and seismic structural measures.
