  A statistical combination of searches for heavy resonances decaying to pairs
of bosons or leptons is presented. The data correspond to an integrated
luminosity of 35.9 fb$^{-1}$ collected during 2016 by the CMS experiment at the
LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. The data
are found to be consistent with expectations from the standard model
background. Exclusion limits are set in the context of models of spin-1 heavy
vector triplets and of spin-2 bulk gravitons. For mass-degenerate W' and Z'
resonances that predominantly couple to the standard model gauge bosons, the
mass exclusion at 95% confidence level of heavy vector bosons is extended to
4.5 TeV as compared to 3.8 TeV determined from the best individual channel.
This excluded mass increases to 5.0 TeV if the resonances couple predominantly
to fermions.
