Shear Distribution Research Of Frame Work-core Wall Structure Under The Earthquake Effects

China is a very serious earthquake disaster country. With the development ofChina’s social and economic, infrastructure has increased a lot, not only buildingscaleincreased, many new structures and complex structures also emerged, includingsome high-rise and super high-rise building based on Framework-core wallstructure.As the most widely used high-rise structural system, framework-core wallstructure has dual systems for seismic design. As the first line of earthquake defense,generally the core wall shear wall have a large stiffness, which can share most of theseismic forces, so the walls are easy to t crackor damage. Framework as the second lineof defense must have sufficient capacity and rigidity to bearthe transfer of internalforces afterthe first line of defense stiffness degradation. To guarantee the safety of thebuilding andprevent collapse, ensure the safety of the lives of persons in the building.This subject committed to the framework-core wall structure under the earthquakeshear in order to find out the wall and column elements distribution law. The study issummarized as follows.（1）Use engineering analysis software PKPM, analysis the structural model underthe response spectrum seismic forces, in order to discover the laws.（2） Use engineering analysis software MIDAS/GEN, analysis the structuralmodel undersmall earthquake seismic force, structure and components are in the elasticstate, in order to discover the laws.（3） Use engineering analysis software PERFORM3D, analysis the structuralmodel in rare earthquake seismic force, Structure and components are in theelastic-plastic state, in order to discover the laws.Research on the subject main on framework-core wall structure of the horizontalseismic shear force distribution law and the influencing factors, then draw someconclusions, in order to provide some references for Framework–core wall structuredesign and analysis.
