Abstract:
The design and analysis of multi-storey structures have always posed significant challenges, particularly in balancing structural stability, material efficiency, and cost-effectiveness. One of the key factors in achieving this balance is the inclusion of lateral force-resisting systems, such as shear walls, which provide crucial resistance to wind and seismic forces. This study investigates the performance of three structural models under various loading conditions: a simple frame (Model M1), a frame with a full shear wall (Model M2), and a frame with a shear wall containing pockets (Model M3). The type of analysis done was Equivalent static method. The core objectives of the study were to evaluate the impact of shear wall openings on the structural behaviour of the building, focusing on key parameters such as base shear, axial force, overturning moment, storey drift, storey displacement, torsion, and steel reinforcement requirements by using STAAD Pro software, and results were compared across the three models. The findings of the study revealed that the Model M3, which includes pockets in the shear wall, demonstrated a favourable balance between structural performance and material usage. Model M3 exhibited lower base shear and axial force than Model M2, while maintaining comparable resistance to overturning moments. Although the storey drift and torsion were slightly higher in Model M3, the model demonstrated reduced storey displacement and required similar levels of steel reinforcement as the simple frame (M1), making it a cost-efficient design option. In conclusion, the study confirms that shear walls with pockets (Model M3) can be an effective design choice for optimizing both structural performance and resource efficiency. Future work could expand on this analysis by exploring the impact of different pocket sizes and configurations, as well as the behaviour of such models under varying dynamic loads, particularly seismic forces in high-risk areas.
