Study on local failure of ring suspended steel structure during lifting
Taking the Beijiang Pearl Tower revolving restaurant was lifted as an example,the finite element analysis software ABAQUS was used to construct the finite element model of the Beijiang Pearl Tower,and the"life and death element"technology was applicd to simulate component failures at different locations,the influence of different forms partial component failure on the force performance of the revolving restaurant during lifting was analyzed,and the reliability of the finite element model was verified by field measurement data.The results show that when the components near the lifting points fail individually,they have a greater impact on the structural stress and displacement,and before the structure is fully lifted,the later the component fails,the greater the stress before the component failure,the more obvious the structural dynamic response.In addition,the effect of simultaneous failure of different components on the structure is greater than the superposition of peer component,the effect of simultaneous failure of unconnected components is greater than the connected component,and the effect decreases with increasing the distance between the failed components.
