Analysis on Axial Compression Ratio to Strong Column Weak Beam Effect in Framework Node

Article Preview

Abstract:

Nodes of Column ends, included ordinary Intermediate nodes and nodes in the model of carbon fiber, have been established based on finite element program, have analyzed the comparison of the deformation, bearing capacity, ductility in Quasi static state under three conditions of axial compression ratio reinforcement (0.2, 0.4, 0.6) between reinforcement nodes and ordinary nodes, have researched the impact caused by the change of axial pressure ratio on seismic performance of node, The result have shown that size of the axial compression ratio and bearing capacity of reinforced nodes follow basic plastics performance, but ductility of nodes in low axial compression ratio is more effective.
