| 標(biāo)題 |
| 熱點(diǎn)應(yīng)力法在鋼橋構(gòu)件疲勞評(píng)定中的應(yīng)用方法及實(shí)例(50 卷) |
| 英文標(biāo)題 |
| Hot-spot stress method and its application in fatigue assessment for steel bridge members |
| 摘要 |
| 介紹了熱點(diǎn)應(yīng)力法在焊接板結(jié)構(gòu)中的應(yīng)用現(xiàn)狀，給出了采用有限元法確定鋼橋構(gòu)件熱點(diǎn)應(yīng)力時(shí)的單元類型、單元尺寸的選擇及外推計(jì)算方法。并對(duì)一座實(shí)橋采用熱點(diǎn)應(yīng)力法對(duì)其縱梁腹板豎向加勁肋下端焊趾進(jìn)行了疲勞評(píng)定，計(jì)算結(jié)果與實(shí)際結(jié)構(gòu)狀態(tài)較為吻合，表明采用熱點(diǎn)應(yīng)力法對(duì)鋼橋構(gòu) |
