| 英文標(biāo)題 |
| Measurement and analysis on vibration characteristics of composite girder bridge with corrugated steel webs |
| 摘要 |
| 以波形鋼腹板組合梁橋?yàn)檠芯繉?duì)象，采用跳車激勵(lì)法對(duì)其進(jìn)行了振動(dòng)特性試驗(yàn)，根據(jù)橋梁結(jié)構(gòu)的時(shí)域波形，頻譜圖和功率譜圖，得出了其自振頻率、阻尼比、振型等振動(dòng)參數(shù)。利用有限元理論對(duì)結(jié)構(gòu)整體進(jìn)行動(dòng)力特性計(jì)算，分析了結(jié)構(gòu)的前20階的自振頻率和振型。對(duì)比實(shí)測(cè)和理論計(jì)算結(jié)果 |
