摘要(Abstract):

以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,用试验结果标定有限元模型。在此基础上,对管幕结构不同荷载阶段下的变形和应力进行分析,并研究了钢管厚度,翼缘板厚度,螺栓直径等参数对STS管幕构件延性的影响。结果表明:钢管厚度的变化,对试件的延性影响较大;翼缘板厚度的变化,能显著提高试件的延性;螺栓直径的变化,对试件的延性影响不明显。
Based on the experimental results of STS(Steel Tube Slab) specimens,the elaborate element models are proposed to sufficiently study on the mechanical properties of STS specimens,the finite element model is verified by using the experimental results. On this basis,deformation and stress of every stage of STS structure were analyzed,and analysis on influence of steel thickness,flange thickness and bolt diameter on mechanical properties of STS specimens was operated. The results indicate:steel thickness has had a big impact on ductility of STS specimens; flange thickness has a notable improvement on ductility of STS specimens; however,bolt diameter and reinforcement ratio have little influence on ductility of STS specimens.
