A dowel shear force transmitted across the crack by flexural (tension) reinforcement V d (15 to 20%). However,the remaining shear capacity can be shown to end up being unrealistically low when compared to earlier research at the TUD,indicating 55% of the shear capacity of a solid slab with the same thickness and material properties to be Someone out there correct me if I am wrong but dowel pins are not designed to carry a load.They are strictly used for locating purposes.The loadI am using the dowels to locate two faces which are bolted together.In order to locate,the dowel hole clearance has to be less than the bolt clearattler,I think what is going in here is that the bolts,when torqued to the proper spec,will see the load before the dowels ever would.If the tGeneral design practice is for dowels to carry shear forces while bolts/screws carry tension forces.
