The bolt s dimensioning concrete strength is C25 30 for both normal and shear force The bolts cannot. be used with lower concrete strengths The dimensioning is made for split concrete and the bonding. condition is good The bolt s normal force resistance in higher strength and structure classes is in. accordance with Table 5 Failure cone resistances and minimum distances are calculated according to. the higher concrete strength used, User Manual ATP and AHP Rebar Bolts Revision 12 2017. ATP and AHP Rebar Bolts,User Manual, The bolt s shear resistance in concrete is always calculated according to the foundations actual concrete.
strength and the bolt s edge and centre distance The concrete shear resistance increases as the edge and. centre distance and concrete strength increase The values in Table 8 are values for the bolt s minimum. dimensioning situation with edge distance c4 provided in the table. 4 3 Transferring the column s shear force to the grouting and foundations. The column s shear force is transferred during the final stage from the column through the grouting to. the foundations using three different methods whose use is selected by the designer in the software s. load combination, 1 Friction force The shear force is transferred from the column to the grouting and foundations. through friction force, The shear force is transferred through the friction of the concrete of the column and. the bottom surface of the shoe base plate to the grouting and from there to the. concrete of the foundations, The bolts do not computationally take part in transferring the shear force. Shear wall connection The friction force is calculated according to the resistance at. the interface between concrete cast at different times under SFS EN 1992 1 1. Section 6 2 5, Column shoe connection The friction force is calculated with friction coefficient. 0 2 under SFS EN 1993 1 8 Section 6 2 2 The rest of the shear force is transferred. through the bolts, The methods are applied when the normal force of the column remains compressed.
and the friction force coming from the normal force is sufficient for transferring the. shear force, 2 Bolt s edge The shear force is transferred through the bolt s edge compression. compression The shear force is transferred through the edge compression of the column shoe or. steel column base plate hole to the bolt from which the force is transferred through. the bolt to the concrete of the foundations, The dimensioning is performed according to SFS EN 1993 1 8 Section 6 2 2 8. The hole in the shoe base plate is 9 15 mm larger so the column moves the distance. allowed by the play of the hole before starting to act on the shear edge compression. This option significantly increases the stresses on the bolt and reduces the bolt s. combined normal and shear force resistance in the grouting connection. The column s displacement by the play of the hole must be taken into account. The shear force is transferred from the concrete column through a compressed shoe. 3 Shear dowel The shear force is transferred using a steel dowel. This method is used in steel column connections where a steel profile has been. welded to the bottom surface of the base plate and its dowel effect transfers the. shear force through the grouting directly to the concrete of the foundations. The anchor bolts do not computationally take part in transferring the shear force. 4 4 Bolt connection design instructions for the main structural designer. The bolt connection is designed using the AColumn dimensioning software Due to the calculation. method no instructions are provided for manual calculation and the use of bolts in detail design with. approximate calculation methods is not recommended The software is used for designing bolts in the. following connection types,1 Column shoe Frame column connections. connections Shoe connections in element column extensions. Shoe connections to foundation columns and cast in place footings. Rectangular and round columns,APK C APKK C and AHK AHK K shoes. 2 Wall shoe Stiffening wall, connections Extension and foundation connections of stiffening element walls.

The following dimensioning criteria and standards are taken into account in designing bolt. connections,1 Dimensioning standards and load combination. The bolt connection is designed according to the CEN TS 1992 4 2 standard applying SFS EN. European standards Before using the software the force combinations acting on the bolt. connection are calculated using separate dimensioning software applications The software can also. be used to dimension the connection using the Basic Eurocode and according to the Swedish and. German National Annex,2 Dimensioning for the erection stage.
The bolt connection works during the erection stage without grouting The shoe and bolt. resistances are calculated for the forces provided for the erection stage using the AColumn. software The normal force on the connection is transferred through the bolts and the shear force. through the bolts bending and shear The thinness and bending resistance of the bolts is taken into. account according to the grouting thickness,3 Dimensioning for the final stage. The factors of consequence classes CC1 CC3 are taken into account in the load combination The. bolt connection works during the final stage when the concrete of the foundations and grouting of. the connection have hardened The software calculates the bolt resistances for normal and shear. The factors of consequence classes CC1 CC3 are already taken into account in the load. combination The bolt connection works during the final stage when the grouting of the connection. has hardened The software calculates the connection as a bent and compressed structure where the. tensile force is transferred through the bolt shoe and the compressive force is transferred through. the concrete of the column and the shoe anchor bolts The shear force on the connection is. transferred according to the principles indicated in Section 4 2 2. The software calculates the necessary supplementary stirrups in the bolt area and performs the. dimensioning of the bolts and their required supplementary reinforcement in the foundations. 4 Dimensioning for fire situations, The bolt connection is designed in the same fire resistance class as the frame The bolt must be. located at a sufficient concrete layer distance from the edge of the structure in the grouting and. foundations,5 Loads including dynamic effects, Loads including dynamic effects are taken into account according to SFS EN 1990 1 Section. 4 1 5 by multiplying the static specific loads by the corresponding dynamic enlargement factors. With the forces calculated in this way the dimensioning is performed as a static situation. 6 Loads caused by earthquakes, Earthquake dimensioning is taken into account in calculating the final stage according to SFS EN. 1991 1 in formulas for the load combination 5 With the forces calculated in this way the. dimensioning is performed as a static situation A separate software application is used to calculate. the connection forces for the load combination for earthquakes The partial safety factor level of the. load is selected in accordance with the European standards.
