Research on the design of connected structure with great difference in dynamic characteristics of two towers
The 2# C Tower of first phase project in the Xiamen industrial park is a frame-shear wall with connective structure,which has some irregularities such as irregular torsion,eccentric arrangement,irregular plane,Structural width size mutation,and connective struc-ture.The dynamic characteristics of the two towers are quite different in the plane spindle direction,and the whole is formed by the strong connection mode of steel structure truss from 7 floor to the roof.The span of the connective structure is 30 meters,based on the seismic performance design,setting reasonable seismic performance objective,combining with the dynamic elastic-plastic time history analysis under rare earthquakes,and taking strengthening measures for the weak parts and key parts of the components to achieve the goal of safety and comfort through the stress analysis,construction sequence simulation and floor comfort of the transfer truss.
