巨型型钢混凝土框撑-核心筒结构是由巨型型钢混凝土框架、巨型支撑、混凝土核心筒和伸臂桁架组成的一种具有多道抗震防线的新型超高层结构体系。对设置X形和倒V形巨型支撑以及设置巨型支撑的同时去除巨型梁下层次柱的结构体系进行了分析。结果表明:设置X形巨型支撑可以使结构的整体刚度明显增大,提高了框架作为第二道抗震防线的承载力;倒V形巨型支撑对结构刚度的贡献相对较小,但引起的局部构件内力突变也较小;设置巨型支撑的同时去除次柱会造成局部构件的内力突变,但可以使巨型框架的主、次结构受力更明确,提高主结构的效率,同时满足建筑大开间的要求。
Giant SRC framed-core tube structure is a new type of super high-rise structural system with multiple anti-seismic lines consisting of a huge steel reinforced concrete frame, a huge support, a concrete core tube and a telescopic truss. The structural system of setting the X-shaped and inverted V-shaped giant supports and setting the giant supports while removing the lower column of the giant beams is analyzed. The results show that the X-shaped giant brace can increase the overall stiffness of the structure significantly and increase the bearing capacity of the frame as the second seismic defense line. The contribution of the inverted V-shaped giant brace to the structural stiffness is relatively small. However, The sudden change of internal forces is also small; the removal of the secondary columns while the giant supports are installed can cause sudden changes in the internal forces of the local components, but the force of the main and secondary structures of the mega-frame can be more clearly defined, the efficiency of the main structure can be improved, .
