RECONSIDER OF RELATIONAL EXPRESSION BETWEEN SHEAR FORCE AND RELATIVE SLIP OF PERFOBOND STRIP WITHOUT PENETRATING REBAR

Abstract

 In the general design of the steel concrete hybrid structures, the relative slip between the steel part and concrete part is usually ignored. However, the numerical analysis which simulate the behavior up to the ultimate stage of hybrid structures is becoming possible by setting appropriately the shear force-relative slip relation to the shear connector element. In this study, the perfobond strip without penetrating rebar was focused, and its shear force-relative slip relations obtained by push-out tests, was compared to the standard specifications for hybrid structures of JSCE. After that, the relational expression of shear force-relative slip was reconsidered to increase the correlation with the experimental value.
