Analysis of Seismic Resistance and Structural Stability of a Multi-Story Reinforced Concrete Building: A Comparative Study of Heavy and Lightweight Concrete (The Case of Tbilisi)

Abstract

This paper examines the methodology and calculation results for the construction of a 20-story reinforced concrete building designed in the city of Tbilisi. The study includes a dynamic analysis of the building under seismic and wind loads using the "LIRA SAPR 2024" software package. The primary goal of the work is to evaluate the impact of using heavy versus lightweight concrete on the load-bearing capacity and economic efficiency of the building. Results indicate that the use of lightweight concrete significantly reduces the building's self-weight, which is directly proportional to the reduction in seismic loads
