【摘要】：對(duì)往復(fù)荷載作用下鋼管混凝土框架結(jié)構(gòu)進(jìn)行了有限元模擬,并與試驗(yàn)結(jié)果進(jìn)行比較,結(jié)果表明有限元分析值和試驗(yàn)值吻合較好。在此基礎(chǔ)上,采用時(shí)程分析法比較鋼管混凝土框架結(jié)構(gòu)和鋼筋混凝土框架結(jié)構(gòu)在天津波作用下的動(dòng)力響應(yīng),比較了框架頂層位移和加速度,綜合評(píng)定二者的抗震性能。分析結(jié)果表明:在多遇地震作用下,二者頂層位移均小于3 mm,頂層加速度均小于70 mm/s~2,框架結(jié)構(gòu)處于彈性狀態(tài),鋼管混凝土框架結(jié)構(gòu)較鋼筋混凝土框架結(jié)構(gòu)的抗震性能優(yōu)越性不明顯;在罕遇地震作用下,鋼管混凝土框架結(jié)構(gòu)頂層最大位移和加速度分別為14.06 mm、409.50 mm/s~2,鋼筋混凝土框架結(jié)構(gòu)頂層最大位移和加速度分別為15.60 mm、199.36 mm/s~2,框架結(jié)構(gòu)處于彈塑性狀態(tài),鋼管混凝土框架結(jié)構(gòu)比鋼筋混凝土框架結(jié)構(gòu)承擔(dān)更多地震作用,鋼管混凝土框架結(jié)構(gòu)的抗震性能明顯優(yōu)于鋼筋混凝土框架結(jié)構(gòu)。
[Abstract]:The finite element simulation of CFST frame structure under reciprocating load is carried out, and the results are compared with the experimental results. The results show that the finite element analysis value is in good agreement with the experimental value. On this basis, the dynamic responses of concrete-filled steel tubular frame structure and reinforced concrete frame structure under the action of Tianjin wave are compared by time-history analysis, and the displacement and acceleration of the top floor of the frame are compared, and the seismic performance of the two structures is comprehensively evaluated. The results show that the displacement of the top floor is less than 3 mm, the acceleration of the top layer is less than 70 mm / s ~ (2), and the frame structure is in an elastic state. The seismic performance of CFST frame structure is not obvious than that of reinforced concrete frame structure. The maximum displacement and acceleration of the top floor of CFST frame structure are 14.06 mm ~ 409.50 mm / s ~ (-2), respectively, and the maximum displacement and acceleration of the top layer of reinforced concrete frame structure are 15.60 mm / 199.36 mm / s ~ (-2) respectively. The frame structure is in an elastic-plastic state. Concrete filled steel tubular frame structure bears more earthquake than reinforced concrete frame structure, and the seismic behavior of concrete filled steel tube frame structure is obviously better than that of reinforced concrete frame structure.
