Mechanical Analysis and Collapse Behavior of Steel Truss Structure During Construction
Steel truss structures are often accompanied by redistribution of internal forces in the construction process.It is of great significance to study the change of internal forces and collapse resistance in the whole construction process of steel truss structures.In this paper,the steel truss construction of Xiongan Science and Innovation Park Gymnasium is taken as the research object,and the mechanical properties and collapse resistance analysis of the whole construction process are studied by combining in-site measurement and numerical analysis.The results show that the measured data are consistent with the numerical simulation results,which verifies the validity of the numerical simulation method.Through the optimization and demonstration of the scheme,the construction is simpler,faster and safer by setting the auxiliary construction method of steel strand.The failure of single lateral steel column can not cause collapse of structure,while the failure of double lateral steel column has collapse risk,the structure has a certain safety reserve.
