Abstract:The seismic action, effect and overall stability of super high-rise mega structures in high seismic fortification intensity region were analyzed and studied, and the mass distribution method of seismic shear force was proposed. Principle analysis and design research on the combined action and crack resistance of embedded steel plate concrete composite shear wall, and the combined action of multi-cavity concrete filled steel tubular mega column were carried out. Engineering practice and monitoring results show that the seismic effect of the above-mentioned walls and columns is very ideal. Finite element analysis and experimental study on bifurcated joints of mega columns were carried out to verify that the joints can meet the performance objectives under the frequent, fortification and rare earthquakes. The experimental study on the embedded steel plate braced concrete composite shear wall was carried out. The elastic-plastic time-history analysis of the structure under the rare earthquake shows that the structure has good ductility and effectively improves the damage degree of the corewall. The experimental verification of the steel energy-dissipated dual coupling beam damper shows that the steel energy-dissipated dual coupling beam damper can effectively reduce the stiffness degradation of concrete beams. Composition and shear capacity of high strength concrete composite wall with three steel plates were analyzed. Seamless design of pile-raft foundation was realized by using variable stiffness leveling design theory, and differential settlement and total settlement deformation were well controlled.
