| 混凝土橋梁裂縫特性及其對(duì)結(jié)構(gòu)固有振動(dòng)的影響分析(51 卷) |
| 英文標(biāo)題 |
| Analysis of crack feature of concrete bridge and its influence on natural vibration of structure |
| 摘要 |
| 詳細(xì)介紹混凝土橋梁結(jié)構(gòu)開(kāi)裂理論、裂縫種類(lèi)及其具體成因，研究混凝土橋梁裂縫損傷對(duì)結(jié)構(gòu)動(dòng)力特性的影響。采用單元?jiǎng)偠韧私的M結(jié)構(gòu)裂縫，以簡(jiǎn)支梁、連續(xù)梁和拱分別模擬單一單元不同位置、不同程度損傷及不同結(jié)構(gòu)長(zhǎng)度損傷的情況，系統(tǒng)分析裂縫損傷對(duì)固有振動(dòng)特性的影響。結(jié)果 |
