Seismic Behavior Of Special-Shaped Column And Beam Column Joint Of Honeycomb Steel Reinforced Concrete

Honeycomb steel-reinforced concrete component is the main load-bearing component of building structure.Compared with structural components under static load,it is often used in high-rise,complex structure,super high-rise buildings,because it not only has excellent strength,but also has good Its seismic performance can better improve the bearing capacity,seismic performance and ductility of the structure.Compared with ordinary steel-reinforced concrete members,the bonding force of the materials in the honeycomb steel-reinforced concrete members is relatively stronger,especially in the condition of common stress,which can greatly strengthen the combination of steel and concrete.Have the ability to work together,and save materials.At present,there are few studies on the seismic performance of honeycomb steel-reinforced concrete members,and there are few finite element simulation studies.Therefore,the finite element research on honeycomb steelreinforced concrete members is very necessary.This paper mainly studies the seismic performance of honeycomb steel reinforced concrete special-shaped columns and beam-column joints.Through the finite element simulation of 8beam-column joint members and 14 internally-matched reciprocating,low-cycle load,the steel honeycomb steel-reinforced concrete column members are subjected to finite element simulations.By changing various parameters,the research focuses on the Basic mechanical properties,failure modes of special-shaped columns and beam-column joints,load-bearing capacity,energy dissipation capacity,and the effect of large axial compression ratios on component performance.According to the failure form of the component,analyze the many mechanisms in it.In the process of studying the seismic performance of many components of honeycomb steel-reinforced concrete,carry out relevant comprehensive analysis on the skeleton curves,energy dissipation capacity,strength degradation and other aspects of the component,and focus on exploration The influence law of honeycomb steel-reinforced concrete special-shaped columns and beam-column joints on seismic performance.The simulation results show that compared with traditional reinforced concrete members,honeycomb steelreinforced concrete members have outstanding earthquake resistance and energy dissipation capabilities.Shaped steel is the second line of defense for honeycomb steel-reinforced concrete components.Increasing the steel-bearing ratio within a certain range can increase the initial stiffness and ductility of the component in the ultimate state;with the increase of concrete strength As a result,the ultimate bearing capacity of the component is also increased.When the concrete is crushed and the bearing capacity of the component turns to the steel frame,the component still has the bearing capacity-this is due to the strengthening of the steel fram...
