HILTI HY 150 REBAR DESIGN GUIDE1HILTI HY 150 REBAR DESIGN GUIDEHILTI HY 150 REBAR DESIGN GUIDE2HY150 Rebar Dowelling using Limit States Concrete Design ( A23.3-94)The design method presented here was originally based on Eurocode 2: ENV 1992-1-1 Designof Concrete Structures, Part 1, General rules and rules for buildings.The formulas have beenconverted to incorporate the load and reduction factors of A23.3-94.Consequently, this methodonly applies to reinforced concrete.In the case of non-reinforced concrete, -
- anchor theory must be used.This anchor theory is the basis of the design principles described in the HILTI EngineeringManual i.e.
Reqd spacing and edge distances.HILTIS internal and external testing including a full scale beam test has shown that theperformance characteristics of rebar fastenings with HILTI HIT HY150 correspond to those ofcast-in rebars.All construction rules outlined in A23
.3-94 apply; in particular, the transmissionof the anchoring forces into the connecting building components must be ensured inaccordance with the principles of reinforced concrete construction (e.g.transversereinforcement, concrete cover etc.).In the case of reinforced concrete, the edge distanceand spacing are not of primary importance becausethe tensile force is transmitted by the connectionbetween them.General Rules:To transfer shear loads the surface of the existing concrete should be roughened.The performance characteristics of HIT HY150 correspond to those of cast-in rebars.Allconstruction rules of A23.3 apply; in particular, the transmission of the anchoring forces intothe connecting building components must be ensured in accordance with the principles ofreinforced concrete construction (e.g.transverse reinforcement, concrete cover etc.).If the rebar connection is to be loaded before the concrete reaches its 28 day compressivestrength, the strength at the time of installation should be used with the given formulae.However,special attention should be given to concrete creep.
The formulas used in this guide are based on extensive testing of HILTI HY150 adhesiveand can only be used for HY150.Other adhesive or epoxy products will have different bondstrengths, ductility and load displacement characteristics which would result in differentformulas..
