Abstract:
Four specimens with one-eighth scale one-way hinge details of the type used in highway bridges were tested to study the effect of combined shear and flexure caused by lateral loads. The shear span-depth ratio was changed from one to three. Three of the specimens were subjected to monotonic loads, and one was subjected to cyclic loads. The study showed that, even for the shear span-depth ratio of one, flexure controlled the load capacity and some ductility was evident. The results also showed that the shear friction theory is not appropriate for estimating the shear strength of hinges and that the theory leads to unconservative results. The flexural load capacities were estimated very accurately with commonly used theories. However, the ultimate deflections were underestimated significantly by these theories.
