摘 要: 首先通过有限元法对型钢混凝土纯扭构件进行数值建模并验证其准确性。其次,为研究型钢混凝土构件在纯扭作用下的力学性能,分别从约束范围、配筋率及配箍率三方面对型钢混凝土(steel reinforced concrete,SRC)受扭构件进行数值分析。结果表明,不同影响因素对构件在弹性阶段承载力的影响较小,但对极限承载力影响效果显著。
关 键 词: 土木建筑结构;型钢混凝土构件;纯扭作用;数值分析

Abstract: In this paper, the finite element method is used to model steel reinforced concrete members and verify its accuracy. In order to study the mechanical properties of steel reinforced concrete members under pure torsion, numerical analysis is carried out on the steel reinforced concrete (SRC) torsional members from three aspects of the constraint range, reinforcement ratio and stirrup ratio. The results show that the influence of different factors on the bearing capacity of the member is small, but it has a significant effect on the ultimate bearing capacity in elastic stage.
Key words: civil construction structure; steel reinforced concrete members; pure torsion; numerical analysis
