[摘要] 在汶川漁子溪村災(zāi)后重建工程中，采用了方鋼管混凝土組合異形柱結(jié)構(gòu)體系。利用MIDAS/Gen軟件對其進(jìn)行建模分析，分析了結(jié)構(gòu)在各種工況下的靜力特性，從結(jié)構(gòu)的自振周期、異形柱連接板應(yīng)力、柱底反力、外肋環(huán)板節(jié)點(diǎn)承載力等方面初步驗(yàn)證了設(shè)計(jì)的合理性。對結(jié)構(gòu)的建造方法進(jìn)行了簡單介紹，說明異形柱和外肋環(huán)板節(jié)點(diǎn)施工快捷方便。

Abstract: Special-shaped concrete filled square steel tubular ( SCFST) structure was adopted in Wenchuan reconstruction project. The static characteristics of the SCFST structure was studied based on the MIDAS software. The natural vibration period, the stress of special-shaped column batten plate and the reaction force at the column base were analyzed which could verify the rationality of the design. The construction method of structure was introduced briefly which could show the easy construction of SCFST and the vertical stiffener joint.
Keywords: Wenchuan reconstruction project; special-shaped concrete filled square steel tube; static characteristics; vertical stiffener joint.
