Research on the Application of Mixed Prefabricated Frames in the Seismic Design of Tall Buildings

: As is well known, prefabricated concrete structures have the advantages of reducing on-site wet work volume, fast construction speed, saving materials, being conducive to building industrialization, and having good economic and social environmental benefits compared to cast-in-place concrete structures. Therefore, experts in the engineering industry actively advocate the application of prefabricated concrete structures. From the perspective of its structure, the hybrid prefabricated frame system has the characteristics of light weight, convenient construction, and large span, and has excellent seismic performance. According to the current specifications, propose reasonable seismic performance goals and measures, and conduct dynamic elastic-plastic supplementary analysis. The seismic performance can meet the needs of earthquake resistance, and the corresponding point is defined as the characteristic point of structural seismic performance, which can be based on the corresponding structural base shear force, vertex displacement, interlayer displacement, and crack development situation. Conduct performance testing and research on the seismic performance of the specimen, including hysteresis curve, load-bearing capacity, displacement ductility, strength degradation, and energy dissipation capacity.
