| 摘 要： | 传统的工程结构设计与分析是建立在确定性的力学模型基础上进行的,无法考虑结构中的不确定性.不确定性是人类在认识和把握纷繁复杂客观世界过程中的局限性所客观存在的.通过将结构中的不确定性按照其自身规律表达成概率模型,采用蒙特卡罗法对新建成的一座钢管混凝土拱桥进行分析,不仅获得了关键截面结构应力值概率分布情况,也得到了该桥的体系静力可靠度,较好地分析不确定因素对桥梁结构的影响. |
| 关 键 词： | 可靠度 不确定性 蒙特卡罗法 |

| Abstract: | The traditional design and analysis of engineering structure are based on deterministic mechanic model.Thus,the uncertainty of the structure can not be considered.The uncertainty exists in the process for human beings to understand and master the objective complex world.In this article,the uncertainty of the structure was expressed through a probability model according to its own rules.The Monte Carlo Method was used to analyze a newly-built concrete-filled steel tube arch bridge.Not only the distribution s... |
