Taking the newly - built krka bridge in croatia as the prototype , the paper also proposes a type of new structure of steel and concrete composite truss arch 提出理論極限跨徑與理論可行跨徑的概念,給出混凝土拱橋和鋼拱橋的理論可行跨徑。
It is found in the comparison of the structure with only the concrete arch and steel truss arch , the structure of the steel and concrete composite truss arch has certain advantages in aspects of its structural performance , economy and the structure is a one that deserves research in a further way 最后以克羅地亞新建的克爾卡橋?yàn)樵?,提出了鋼混凝土組合桁式拱新型結(jié)構(gòu),在與混凝土拱和鋼桁拱的比較中可以發(fā)現(xiàn),鋼混凝土組合桁式拱在結(jié)構(gòu)性能、經(jīng)濟(jì)性能上具有一定的優(yōu)越性,值得進(jìn)一步的研究。
The paper carried out elastic response spectrum analysis on staggered truss frame system , input two strong ground motion records to carry out elastic and plastic time - history analysis . the paper compared the difference of aseismic property between 20 - storeyed composite truss and 20 - storeyed braced composite truss , and concluded that longitudinal brace can not only increase the rigidity but also reduce drift displacement of the first storey . in addition , the paper adopted displacement coefficiency in push - over method to obtain object displacement , and gave the failure modes of the two structures respectively 本文對鋼結(jié)構(gòu)交錯桁架體系進(jìn)行了彈性反應(yīng)譜分析、輸入了兩條強(qiáng)震記錄進(jìn)行彈性以及彈塑性時程分析,對比了20層混合式和20層縱向帶支撐混合式在彈性階段及彈塑性階段的抗震性能區(qū)別,得出縱向帶支撐不但有利于增大縱向的剛度,還可以減小結(jié)構(gòu)底層層間變形的結(jié)果;利用pushover的位移系數(shù)方法得出了結(jié)構(gòu)的目標(biāo)位移,并得出了兩種結(jié)構(gòu)的破壞模式。
