Through the comparative text of the four reinforced concrete frames braced with the eccentric steel , which have the same shapes , materials , dimension and the different brace form , several parameters of these frame behavior , such as side stiffness , limit load and energy consume ability , were studied . the limit state of these frames were analyzed 本文通過對四榀具有同一外形尺寸及配筋而具有不同型式的偏心角鋼支撐的鋼筋砼框架和一榀相同尺寸及配筋的鋼筋砼框架的對比性試驗,研究了上述結(jié)構(gòu)的抗側(cè)剛度、極限承載力及結(jié)構(gòu)的耗能等各項指標(biāo),探討了偏心角鋼支撐鋼筋砼框架結(jié)構(gòu)的受力特點,并對其極限狀態(tài)進(jìn)行了理論上的分析。
Based on the results , the eccentrically braced frame has the advantage of higher initial stiffness , load - bearing and energy consume ability . through the limit state analysis principle , the limit load was calculated by assuming the same destroy pattern of braced frame as that in the experiment . comparing the theory limit load with the measured , a good agreement was founded . it shows that the limit state analysis is really a practicable way analysed the reinforced concrete frame braced with eccentric steel 應(yīng)用極限分析中的極值原理對偏心角鋼支撐鋼筋砼框架進(jìn)行極限分析時,首先擬定與試驗結(jié)果相一致的結(jié)構(gòu)倒塌破壞模式,然后根據(jù)虛功原理建立了結(jié)構(gòu)在極限狀態(tài)時極限承載力的計算公式,從所求的權(quán)限荷載的理論值與實測值的比較來看,理論計算值與試驗的實測值基本吻合,這說明利用本文擬定的結(jié)構(gòu)破壞模式對偏心角鋼支撐框架結(jié)構(gòu)進(jìn)行極限分析是一條可行的途徑。
