| 鋼拱橋極限承載力的綜合三因素檢算方法(26 卷) |
| 英文標題 |
| Research on Synthetical 3 Factors Checking Method for the Ultimate Load Carrying Capacity of Steel Arch Bridges |
| 摘要 |
| 通過鋼拱橋非線性計算及結果的分析，得出結論，鋼拱橋極限承載力的實質是拱肋截面的材料屈服，隨著塑性區(qū)的擴展，截面剛度降低，從而導致整體非線性位移的急劇增加。運用統(tǒng)計回歸，逐一分析橫向初始缺陷與橫向位移因素指標R1l 、拱圈整體橫向剛度因素指標R2l和拱橋非保向力因 |
