“…The critical load of the structure decreases as a increases and the value of b determines whether bifurcation point buckling or limit point buckling will occur in a truss structure. (5) The analysis method based on movable boundaries has higher computational efficiency and accuracy. It is suitable for cranes with luffing boom and has practical implications for the safe design of giant cranes.…”

The tower crane is a typical soaring and complex frame structure, and buckling is an important factor affecting its safety and carrying capacity. Considering the special characteristics of the boundary conditions for the boom structure, a numerical analysis method based on movable boundaries is proposed in this paper. In order to demonstrate the accuracy of the method, numerical analysis and stress tests are carried out on the tower crane. The results show that the numerical results are basically consistent with the experimental results. A geometric buckling analysis for extremely severe conditions is carried out in order to understand the buckling behaviors. The failure modes and complete load-response curves obtained for the tower crane are comprehensively analyzed. A dual (geometric and material) nonlinear buckling analysis of the tower crane is then investigated. Finally, the influences of the deflection load parameters on the buckling response of the tower crane are explored. It is demonstrated that bifurcation point buckling and limiting point buckling are excited by different deflection load parameters, respectively. The proposed method can accurately predict the buckling of the tower cranes, given the coupling of structure and mechanism, to ensure the safety of giant cranes in actual engineering use.

Functionally graded material (FGM) arches may be subjected to a locally radial load and have different material distributions leading to different nonlinear in-plane buckling behavior. Little studies is presented about effects of the type of material distributions on the nonlinear in-plane buckling of FGM arches under a locally radial load in the literature insofar. This paper focuses on investigating the nonlinear in-plane buckling behavior of fixed FGM arches under a locally uniformly distributed radial load and incorporating effects of the type of material distributions. New theoretical solutions for the limit point buckling load and bifurcation buckling loads and nonlinear equilibrium path of the fixed FGM arches under a locally uniformly distributed radial load that are subjected to three different types of material distributions are derived. The comparisons between theoretical and ANSYS results indicate that the theoretical solutions are accurate. In addition, the critical modified geometric slendernesses of FGM arches related to the switches of buckling modes are also derived. It is found that the type of material distributions of the fixed FGM arches affects the limit point buckling loads and bifurcation buckling loads as well as the nonlinear equilibrium path significantly. It is also found that the limit point buckling load and bifurcation buckling load increase with an increase of the modified geometric slenderness, the localized parameter and the proportional coefficient of homogeneous ceramic layer as well as a decrease of the power-law index p of material distributions of the FGM arches.
