This paper reflects the heavy Higgs scenario where the mass of charged Higgsis equal to or greater than 200 GeV. The CMS observed and expected values ofupper limits on the product $\sigma_H^\pm BR(H^\pm \rightarrow tb^\mp)$,assuming $H^\pm \rightarrow tb^\mp=1$, both at 8 TeV (at integrated luminosityof 19.7 $fb^{-1}$ ) and 13 TeV (at integrated luminosity of 35.9 $fb^{-1}$ )c.m energies are used. By comparing these expected and observed upper limitswith computational values , we find out the expected and observed exclusionregions of charged Higgs parameter space ($ m_H^\pm - tan\beta $ space ) in2HDM both at $\sqrt{s}=$8 and $\sqrt{s}=$ 13 TeV. We compare the expected andobserved exclusion regions and observe that exclusion regions made by observedupper limits are always greater than the exclusion made by expected upperlimits both at 8 and 13 TeV c.m energies. Only in the mass range from 200 GeVto 220 GeV the expected exclusion region is greater than the observed one onlyat $\sqrt{s}=$13 TeV. We also equate the exclusion regions at these twodifferent center of mass energies and find that the expected exclusion regionand observed exclusion region at $\sqrt{s}=$13 TeV are always greater than theexpected exclusion region and observed exclusion region at $\sqrt{S}=$8 TeVrespectively.
