A Theoretical Investigation of the Failure of Open Sandwich Beams due to Interfacial Shear Fracture

The susceptibility of open sandwich beams (concrete/adhesive/steel) to static fracture by crack propagation along the adhesive layer is investigated, using linear elastic fracture mechanics. lt is found that beams constructed with a suitable adhesive should not be at risk from such failure, whether they are conventionally reinforced beams strengthened by an externally bonded plate or plain concrete beams rein forced solely by an external plate.
