Abstract

Seismic resilience in structural engineering is a paramount concern, particularly in regionsprone to seismic activity. This research investigates the seismic performance of reinforced concretestructures with shear walls, employing two distinct design methodologies: Direct Displacement-BasedDesign (DDBD) and traditional Force-Based Design (FBD). Utilizing advanced computational toolssuch as ETABS software and the Response Spectrum Method, a comprehensive comparative analysis isconducted across multiple seismic zones, including Zones III, IV, and V. This study also introduces LeadRubber Bearings (LRB) as a base isolation technique to assess its effectiveness in enhancing seismicperformance. The scope encompasses multi-story buildings with varying heights, ranging from G+2 toG+14. Key findings of this research demonstrate that DDBD consistently outperforms FBD in controllingstructural responses, including base shear, and overturning moments, across the entire spectrum ofbuilding heights and seismic zones. Moreover, the study highlights the adaptability and versatility ofDDBD, emphasizing its potential to enhance seismic resilience in a wide range of multi-story structures.
