ObjectivesDuring the mission, the ship may be simultaneously subjected to the combined wave load and underwater explosion bubble pulsation load, resulting in the "superposition effect" of hull response and the loss of total strength of the ship. Therefore, it is necessary to explore the dynamic response law of hull girder under the combined action of above-mentioned loads. MethodsFirst, a simplified hull girder model is established by theoretical analysis, and the bubble pulsation load of underwater explosion and wave load are solved. Then, based on the Hamilton Principle, the differential equations of motion of hull girder at both free ends subjected to the two loads are derived separately and jointly. Finally, based on the solution of the motion differential equation, the hull girder's free vibration response and the simplified model's motion response under the three working conditions of external load combination are analyzed. ResultsThe results show that under the combined action of the two loads, the motion response of the hull girder is 15% larger than the linear superposition of the motion response of the two loads alone. ConclusionsThe research done can provide a reference for developing an algorithm to analyze the motion response of ship structures under combined loads.

Based on the mixed control quasi-static test on eight CFST columns subjected to combined compression, flexure and torsion, the mechanical behavior of CFST columns with various section types, bending moment-torsional moment ratios and axial load was studied. The test results show that the hysteretic curves of CFST columns under combined compression, flexure and torsion are plump due to the good seismic behavior and the ductility is also good. But for rectangular CFST columns with high bending moment-torsional moment ratios, the strength degradation can be observed due to the local buckling of the steel plate at the bottom. The torsion capacity of CFST columns can be reduced by the bending moment. The plane section assumption of axial strain of CFST columns can be satisfied. The shear strain has good linear relationship with the rotation angle of the section when CFST columns are subjected to combined compression, flexure and torsion. Based on the test results and literatures available, the mechanism of CFST columns is analyzed in details. The research foundation is established for the development of beam-column element of CFST columns considering torsional effects. [ABSTRACT FROM AUTHOR]
