| 圓中空夾層鋼管混凝土壓彎構(gòu)件滯回模型研究(51 卷) |
| 英文標題 |
| Study on hysteresis model of circular hollow steel tubular concrete member subjected to compression-flexure action |
| 摘要 |
| 利用有限元方法，對往復(fù)荷載下圓中空夾層鋼管混凝土壓彎構(gòu)件的荷載—位移全過程進行了計算，有限元模型中考慮了往復(fù)荷載下混凝土的剛度和強度退化，同時考慮了鋼材的包興格效應(yīng)，計算結(jié)果與試驗結(jié)果符合較好。在此基礎(chǔ)上，分析了構(gòu)件名義含鋼率、軸壓比、長細比、空心率等對 |
