Structural design of herringbone structure surrounded on three sides—Beijing N apartment
Based on a large-span inclined connection three-tower structure project,small earthquake elastic analysis,time history analysis and large earthquake dynamic elastic-plastic analysis method were compared through the multi-software,the force transmission path of the inclined connection,the calculation and analysis of the inclined connection over-limit high-rise structure,the anti-progressive collapse checking of the inclined connection and finite element analysis of key nodes of the weak connection between the inclined connection and the tower were analyzed.The analysis results show that the force transmission path of the inclined connection is reliable,and oblique connecting body and the key force transmission nodes connected with the tower do not yield under rare earthquake,and the overall structure meets the deformation and bearing capacity requirements under rare earthquake.Therefore,the structural arrangement of this project is reasonable and the structural system is safe and reliable.
