Abstract
Tower crane belongs to tall towers truss structures, whose bucking instability often lead to collapse. Past studies focused on the mast instability under a single load, which doesn’t apply to the actual condition that tower crane working under various loads at the same time. This paper taking into consideration the tower crane lifting weight as well as various loads like the hoist tipping moment, heavy vertical load, wind load, the centrifugal force, rotary load of resistance and horizontal inertia force. Through the eigenvalue bucking and nonlinear bucking analysis, we can get the lifting load when the hoisting is focusing on a maximum working range of the arm of the tower and tower bar force status and the convergence map of stability. This study provides the complete steps of the tower stability design of tower crane, can be used as a guidance or reference for the actual product design.
