| 摘 要： | 某钢结构人行天桥的静载试验结果与理论分析结果偏差较大,为查找原因,首先深入分析试验结果的特征,推断出其主要原因,然后通过进一步的有限元理论分析证明了这种推断的准确性,最后还讨论了这种偏差导致结构受力的变化。

| Abstract: | In order to find the reasons for the measured result deviation from the theoretical value of a steel bridge static loading test,the character of test result is deeply analyzed first in this paper. Then the main reason for this deviation can be deduced. Through the structural detail analysis of the key part by finite element method,the main reason of the deviation can be further proved. Lastly,changes in the distribution of structural internal forces led by the deviation are discussed. |
