【摘要】：船舶板架結(jié)構(gòu)在運(yùn)行中難免遭受意外損傷,損傷板架的抗連續(xù)垮塌是業(yè)界普遍關(guān)注的熱點(diǎn)問題。IMO(國際海事組織)要求證明按即將實(shí)施的HCSR(國際共同規(guī)范)設(shè)計(jì)的板架結(jié)構(gòu)具備了抗連續(xù)垮塌能力。 本文首先綜述了結(jié)構(gòu)連續(xù)垮塌問題的國內(nèi)外研究進(jìn)展。對受損板架的損傷模式進(jìn)行了歸納、分析和比較,提出了兩種損傷模型,根據(jù)HCSR規(guī)范屈曲評估方法,給出了損傷板架抗連續(xù)垮塌問題的評估準(zhǔn)則和計(jì)算方法。編制了屈曲利用因子計(jì)算程序,進(jìn)行多艘CSR船舶板架計(jì)算,結(jié)果表明按規(guī)范設(shè)計(jì)的船體板架,在局部受損后仍然具有足夠的抗連續(xù)垮塌的能力。最后結(jié)合CSR實(shí)船的計(jì)算結(jié)果,在適當(dāng)?shù)募僭O(shè)和簡化的基礎(chǔ)上,應(yīng)用過載法推導(dǎo)出一根扶強(qiáng)材破損不導(dǎo)致毗鄰扶強(qiáng)材屈曲的剖面模數(shù)公式。
[Abstract]:During the operation of the ship's slab-frame structure, it is inevitable to suffer accidental damage, The continuous collapse resistance of damaged slabs is a hot issue in the industry. IMO (International Maritime Organization) requires that the structure designed according to the upcoming HCSRs (International Common Specification) has the ability to resist continuous collapse. In this paper, the research progress of continuous collapse of structures at home and abroad is first reviewed. The damage modes of damaged slabs are summarized, analyzed and compared, and two damage models are proposed. According to the HCSR code, the buckling evaluation method is presented. The evaluation criteria and calculation methods for the continuous collapse resistance of damaged slabs are presented. A program for calculating the buckling utilization factor is developed to calculate the slabs of several CSR ships. The results show that the hull slabs are designed according to the specifications. It still has sufficient ability to resist continuous collapse after partial damage. Finally, combined with the calculation results of CSR ship, on the basis of proper assumption and simplification, By using the overload method, a formula of section modulus is derived that the failure of a reinforced wood does not result in the buckling of the adjacent reinforced material.
