Wu, Linmei and Xiaoluo, Cao and Zhenming, Li (2020) Behaviour of steel-reinforced concrete columns under combined torsion based on ABAQUS FEA. Engineering Structures, 209:109980. ISSN 0141-0296
Abstract
A computational model for studying the mechanical performance of steel-concrete columns under combined
torsion is established via ABAQUS. The model is validated by experimental results. Through numerical simulations,
the influence of the axial load ratio, torsion-bending ratio, concrete strength, steel ratio, longitudinal
reinforcement ratio, stirrup ratio, and shear-span ratio on the torsional behaviour of steel-concrete columns is
comprehensively investigated. The initial torsion stiffness and ultimate torsion strength of the column increase with increasing concrete strength and decreasing shear-span ratio. The parameters in descending order of influence on the ultimate torsion strength are steel ratio, torsion-bending ratio, tirrup ratio, longitudinal reinforcement ratio, and axial load ratio. Furthermore, the seven parameters in descending order of influence on the ductility coefficient are the steel ratio, shear-span ratio, concrete strength, axial load ratio, stirrup ratio, torsion-bending ratio and longitudinal reinforcement ratio.
