Abstract
In structural engineering, multi-storey buildings’ seismic resilience in earthquake-prone areas is crucial. The seismic performance of proposed multi-story buildings with different heights (G+13, G+19, and G+27) is thoroughly examined in this study using traditional structural systems that are octagrid and hexagrid. Under seismic zone III conditions, the study evaluates important parameters such as storey drifts and storey displacements using the Response Spectrum Method. Each structural system’s seismic response is assessed using nonlinear dynamic analysis, with an emphasis on classifying bifurcations according to responses that have been observed. The results show that there are notable differences in the seismic performances of the various structural systems, with the diagrid configuration outperforming the others in terms of reducing seismic loads. These findings have implications for designing buildings that are seismically resilient. It is found that the diagrid systems do much better in seismic events by lowering lateral forces and moving buildings less sideways, making it perfect for tall buildings built in places with many earthquakes The results show wide dissimilarity of seismic performance between the various structural systems, diagrid and hexagrid configuration faring better in the reduction of seismic loads than conventional. Findings implications on seismic-resilient building design and construction practices are discussed, with regards to the need to adopt innovative structural systems to promote seismic resilience and safety of building in earthquakes endemic areas. This research provides meaningful insights for structural engineering, notifying the stakeholders and decision-makers about proper strategies for eliminating the seismic hazards and making the environment must safer for inhabitants.
