Connector placement along the beams
The ductile performance of the Hilti X-HVB Shear Connector allows distribution of the calculated required number of X-HVB ’ s uniformly between the points of zero and maximum moment .
Point loads
Application of large point loads causes abrupt changes in shear . To avoid excessive slip , additional X-HVB connectors may be necessary between the point load and the support .
Partial shear connection
AISC-LRFD and AISC-ASD both require that the capacity of the installed shear connectors must be no less than 25 to 50 % of the calculated shear load for full composite design . This requirement is applicable , independent of whether welded studs or X-HVB ’ s are used for the shear connection .
Deflections
Beam deflections are computed by conventional elastic formulas . For beams with partial shear connection , deflections may be estimated by using the following formula for the effective moment of inertia :
I eff
= I s + n x ( l tr
– l s ) l s
= moment of inertia of steel section n = connection fraction
l tr
= moment of inertia with 100 % connection Continuous beams
Hilti X-HVB Shear Connectors are also suitable for use in continuous composite beams . The connectors are distributed uniformly between the point of zero moment and the point of maximum moment .
