In the first operation of the LHC, an analysis searching for new physics using the same simplified model, observed no significant excess of events over the expected SM background. In 2014, the lower limit on the gluino mass was set to be at 1.4 TeV at the 95% confidence level for this simplified signal model. The results presented in this thesis span the first two years of the second operational period of the Large Hadron Collider, during 2015 and 2016, utilizing new techniques of boosted object reconstruction to greatly extend the sensitivity to new physics and improve our understanding of the Standard Model. The lower limit of the gluino mass is now set at 1.95 TeV at the 95% confidence level using three different kinds of kinematic observables: missing energy-type, energy scale-type, and energy structure-type.
