Abstract:
To get load-deformation relationship for reinforced concrete columns subjected to combined action of axial load and lateral load, a new method was developed using simplified modified compression field theory(MCFT)to describe shear behavior, using conventional section analysis to describe flexure behavior, and considering that the total lateral deformation of a column at its ends was comprised of deformations due to flexure, shear and reinforcement slip. The load-deformation courses of reinforced concrete columns failing in flexural failure, flexure-shear failure and shear failure were presented in this method. Finally, the calculation results of load-deformation in the paper were compared with the results of 15 rectangular columns from various low-cycle reverse loading tests. Study results show that the model predicted the load-deformation response envelop reasonably well, so it can be used in load-deformation analysis for reinforced concrete columns subjected to combined action of axial load and lateral load.
