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.
Based on the 8 榀 STS (steel tube slab) pipe curtain indoor test, in order to fully study the mechanical properties of STS pipe curtain, the finite element model of the steel pipe slab was established. The thickness, bolt diameter, reinforcement ratio, The results show that the variation of the thickness of the steel pipe has little effect on the ultimate bearing capacity of the test piece but can effectively increase the lateral rigidity of the test piece and the variation of the spacing of the flange plate. The ultimate bearing capacity and transverse stiffness of the specimens have significant effects. The changes of bolt diameter and reinforcement ratio have no obvious effect on the ultimate bearing capacity and transverse stiffness of specimens.
