The invention relates to a truss type strong frame structure suitable for a polar region ice-resistant platform, which is characterized in that a plurality of horizontal stay bar and diagonal stay bar structures are arranged on a broadside ice load transmission path, and large holes are formed in a small stress area of a transverse strong frame structure to form the truss type strong frame structure. Compared with the prior art, on the premise that the structure safety is guaranteed, the energy transmission efficiency when an outboard ice load acts on the ship body can be improved, the stress horizontal distribution of the whole transverse strong frame structure is uniform, the utilization rate of ship body steel materials is improved, and the purpose of ship body light weight is achieved; and meanwhile, the limitation of the opening range of the broadside strong frame is reduced, the opening area of the transverse strong frame can be increased, and the liquidity of liquid in the broadside liquid tank is improved.
本发明涉及一种适用于极地抗冰平台的桁架式强框结构,在舷侧冰载荷传递路径上设置多根水平撑杆和斜撑杆结构,在横向强框结构应力较小区域设置大开孔,形成桁架式强框结构。与现有技术相比,本发明在保证结构安全的前提下,可提高舷外冰载荷作用于船体时的能量传递效率,使得整个横向强框结构应力水平分布较均匀,提高了船体钢料的利用率,实现了船体轻量化的目标;同时本发明减少了舷侧强框开孔范围的限制,能够增加横向强框的开孔面积,提高了舷侧液舱内液体的流通性。
