Notes:
Although steel-concrete interface has significant influence on bonding strength and shearstrength, the composite structure with the consideration of the interface fracture has been rarelyconducted. In this study, sensitivity analyses are performed to find out steel-concrete interfacecharacteristics by using interface finite elements, defined as elastic-plastic behavior. In order to verifycomputational accuracy, the analyzed interface properties are compared with experimental results.Generally, interface in steel-concrete composite structure plays a critical role of controlling bondingstrength as well as transferring loads between steel and concrete. The composite interface should beavoided to reach to an interface fracture condition; otherwise composite structure may deviate fromintended behavior even under low stress state. It is then led to catastrophic fracture or collapse of thestructure. This study shows that interface properties of steel-concrete can be analyzed by using theinterface element, and the results provide more reliable prediction for the steel-concrete compositebehavior
