📄 Abstract（原文）
In earthquake-stricken areas, the high rise buildings are rapidly appearing, and sustainable and structurally resilient construction materials are required. Although the Ordinary Portland Cement (OPC) concrete is widely used, it is being challenged due to its high carbon emissions and brittle behaviour under severe seismic loading. The fly ash based geopolymer concrete (FAGPC) is an alternative green concrete with good mechanical properties, but the nonlinear seismic response of this concrete type still needs to be studied. In this study, the seismic performance of a G+20 reinforced concrete structure built using M60 grade conventional concrete and fly ash geopolymer concrete are compared. Accurate numerical modeling of material properties is created in ETABS through experimentation. To compare the seismic response of both the building models in terms of base shear, inter-storey drift, roof displacement and plastic hinge formation, nonlinear dynamic time history analysis is performed. The goal of the study is to evaluate the structural behavior and seismic resistance of FAGPC, and to provide a relationship between the material properties measured in a laboratory setting and actual structural performance under seismic conditions in high seismic zones. The results should prove the feasibility of FAGPC as a realistic and reliable material in the future construction of tall buildings.
