T型扶强材在横向载荷作用下的侧向屈曲

考虑船舱进水导致船体梁的结构崩溃而发生沉没的事故中舱壁是一个关键的环节,通过能量法导出舱壁扶强材在侧向静水压力作用下的弹性屈曲的临界载荷公式,与有限元数值计算比较,证明文中计算公式的正确、简单、实用性。

Lateral Buckling of T-Stiffeners under Lateral Loading

In the case of ship collapse of hull girder in flooded condition,the bulkheads are usually the vital structures.The critical load formula of elastic buckling of bulkhead stiffeners under the lateral hydrostatic pressure is derived by the energy method.The comparison with the results of FEM proves that the formula is correct,simple and practical.
