This document discusses the seismic analysis of a high-rise building using outrigger and belt-truss systems. It analyzes a 25-story building considering different floor acceleration ratios under earthquake loads. Response spectrum analysis is performed to determine the building's behavior by examining response parameters like lateral displacement and inter-story drift. Outrigger and belt-truss systems are found to improve the building's stiffness and reduce lateral loads compared to a structure without these systems. The document reviews several other studies analyzing different structural configurations and building heights to determine optimal outrigger locations.
