Study on Seismic Performance of 7A04-T6 Aluminum Alloy Rectangular Pipe Column
In order to study the seismic performance of 7A04-T6 aluminum alloy rectangular pipe column,the loading process of 12 7A04-T6 aluminum alloy moment pipes under the low cyclic loading is simulated on the basis of verifying the feasibility of the finite element model.According to the model results,the influence of slenderness ratio,axial compression ratio and section form on the seismic performance of 7A04-T6 aluminum alloy rectangular pipe column is analyzed.It is concluded that with the increase of slenderness ratio and axial compression ratio,the seismic performance of the component becomes worse,and the web size of the rectangular pipe column corresponding to the loading direction plays a leading role in its seismic performance.At the same time,the skeleton curve model which can be used to predict the seismic performance of 7A04-T6 aluminum alloy rectangular pipe column is proposed,and the accuracy of the model is verified.
