Analysis on Axial Compression Performance and Bearing Capacity of Seawater Sea Sand Concrete-Filled Bimetallic Tube Short Columns
摘要
Abstract
Based on the finite element program ABAQUS,a refined finite element model is established on sea-water and sea sand concrete-filled bimetallic tube(SSCFBT)short columns.The failure mode,load-deforma-tion relationship,internal force distribution,and steel-concrete interface contact of the model under axial com-pression are studied and parametric analysis is conducted.The results show that the co-working performance between the bimetallic tube and the concrete infill is favorable.The load-deformation relationship curves can be divided into three types,which are determined by the confinement factor of the bimetallic tube on the concrete.Through parameter analysis,the influence of different parameters on the axial compressive bearing capacity of SSCFBT short columns is obtained,and the feasibility of related calculation formulas for predicting the axial compressive bearing capacity of SSCFBT short columns is verified.关键词
