New Type Of Buckling Support Damping Energy Consumption Analysis

Prevent buckling support consumption can always be achieved when the tensile or compressive yield and not bent, compared with the traditional support component has more stable mechanical properties, through the reasonable design of the buckling energy support high stiffness and good hysteretic energy dissipation ability, has the good application value.Deformation is big, but unable to auto reply to the initial position after yield.Shape Memory alloys, which has Shape Memory effect Gold.It has superior features, such as shape memory effect, super elastic and damping characteristics, resistance characteristics, Therefore widely used in aerospace, electronic machinery, bridge construction, the automotive industry and other fields,although SMA application in the field of civil engineering is still in its infancy, but because the SMA has excellent features in Structural vibration control show excellent performance, thus gradually by the attention of the researchers at home and abroad.This paper involves a new type of buckling support consumption, realize the conventional prevent buckling energy support perfect combination with shape memory alloy, a new type of buckling constraint support including typical buckling constraint support(can be used to dissipate the earthquake energy) and strong niti shape memory alloy wire(can be used from the reset and reduce seismic energy).Memory alloy wire belong to the buckling constraints pillar of support, as part of the application of the two groups of tie rod and two groups of shape memory alloy wire, when the kernel pressure, pressure, there will be a set of corresponding memory alloy wire stretched.The main work in this paper as follow:1. Designed a buckling energy support, prevention of its structure and working principle in detail in this paper.2. The use of finite element analysis software ABAQUS established the simplified double flag of shape memory alloy constitutive model and the constitutive relation of concrete, core material part of the model.3. Using the ABAQUS finite element analysis software to simulate the new prevent buckling support consumption of restoring force- displacement hysteresis curve, and achieved success.4. Using the time history analysis method to verify the new prevent buckling energy support damping performance.Based on ABAQUS finite element software of multiple degrees of freedom dynamic time history analysis program, used to three layers of steel frame with and without installing new prevent buckling support when the earthquake response of the structure of energy consumption, and to compare the two analysis.
