摘要： 以8榀STS(steel tube slab)管幕构件室内试验为依托，为充分研究STS管幕构件的力学性能，建立构件的有限元模型，分析钢管厚度、螺栓直径、配筋率、翼缘板间距等参数对STS管幕构件力学性能的影响.结果表明:钢管厚度的变化，对试件的极限承载力影响不大，但能够有效地提高试件横向刚度；翼缘板间距的变化，对试件的极限承载力和横向刚度影响较显著；螺栓直径、配筋率的变化，对试件的极限承载力和横向刚度影响均不明显.

Abstract: Based on the experimental results of 8 STS(steel tube slab) components， the finite element models were proposed to study the mechanical properties of STS components， and influence of steel thickness， bolt diameter， reinforcement ratio and flange distance on the mechanical properties of STS component was analyzed. The results indicate: steel thickness has a little influence on the flexural capacity of STS component， but it effectively improves lateral stiffness of STS component; flange distance has a notably influence on the flexural capacity and lateral stiffness of STS component; however， bolt diameter and reinforcement ratio have little influence on the flexural capacity and lateral stiffness of STS component.
