Calculation on the Flexural Rigidity of Steel Reinforced Concrete Eccentrically Compressive Columns by Considering Bond-Slip Effect

摘要

According to the tests of 20 Steel Reinforced Concrete(SRC)eccentrically compressive columns, where the relative eccentricity of loading e0/h、 the slenderness ratio L0/h were taken as the design factors, the calculating model of slip was established by elastic theoretical method. The deformation analysis with regard to slip was also conducted. Therefore, the formula for calculating the reduced rigidity was presented by taking the slip effect into account. This paper will be helpful to the further experimental researches on the bond-slip behaviors of SRC member under eccentric loading. It can also provide references for the deflection calculation and engineering design of SRC eccentrically compressive columns.
