Behaviors of column base connections in assembled steel storage racks
摘要
Abstract
The tests of column base connections in assembled storage racks were carried out to investigate the bending behavior of the connections rotating around the column section’s symmetry axis. The effect of column axial force on the bending property of connections was taken into consideration. The main deformation of tested connections was the distortion of the baseplate and the tear at the column corner weld. Tests indicate that the column axial force is a positive factor for initial stiffness and ultimate moment of connections. These connection tests are numerically simulated using the finite element method, and the test results demonstrate the reliability of the simulation. The conclusions obtained by parameter comparisons include:①The increase of the column axial force is able to enhance the initial stiffness of connection. ② The connection with a larger column axial force has a longer elastic stage in moment-rotation curves. ③ The increase of baseplate thickness is also an efficient method for heightening the stiffness and bending capacity of column base connections.关键词
