| 摘 要： | 结构工程中存在着大量不确定性因素,区间分析方法是计算不确定性结构的最有效方法。但是区间计算的精度偏低使得该方法在实际工程中还很难广泛应用。将PSO算法引入不确定性结构区间分析,将区间计算问题转化为全局优化问题。实例表明,PSO算法的结果明显优于其他现有各种计算方法。 |

| Abstract: | Uncertainties widely exist in structural engineering.Interval analysis is the most effective method to calculate uncertain structure.However,interval analysis could not be applied widely in practical engineering because of low precision.Particle swarm optimization(PSO) is proposed to deal with interval analysis of uncertain structure in this paper to replace interval arithmetic by global optimization.It is shown that PSO has the more precise results than other interval arithmetic. |
