摘要
以加筋板格第II崩溃模式建立单元的应力应变关系,使用简化逐步破坏法编制相应计算程序。通过一系列经典模型的试算和试验值的比较,验证理论和程序的可靠性和正确性。与解析的经验公式进行比较,得出吻合的结果。在此基础上对半潜式平台整体结构的横向极限强度进行研究。
The relationship between strain and stress for the Ⅱ collapse failure model of stiffen panels was presented. Calculation codes were programmed according to simplified progressive collapse method (SPCM). The comparison among the results of model test and other methods indicated that the proposed method and program are correct and reliable. The results in SPCM were consistent with the ones of analytical experimental formula. The transverse ultimate strength of the semi-submersible platform was investigated by using the SPCM program.
