Abstract


This paper investigates the use of textured interface, in the form of expanded metal sheets, to improve the static strength and fatigue performance of steel-concrete-steel (SCS) sandwich beams.  Push-out tests are performed to evaluate the effectiveness of the textured interface to resist shear and to reduce slip between the face plates and the concrete core.   Flexural tests are carried out on SCS sandwich beams to evaluate their load-displacement behavior and ultimate strength.  The combined use of mechanical shear connectors and texture interface bond and their load sharing mechanisms are investigated.  Additional tests are carried out to study the influence of textured interface on the overall fatigue performance of sandwich beams under varying load magnitude and load range.  Fatigue design equation taking into account both stress range and maximum applied stress is proposed for beams with either plain or textured interface.  The paper concludes that the use of textured interface improves the bond and increases the static and fatigue life of composite sandwich beams compared to those with only mechanical shear connectors.
