comparative analysis of transfer slab and transfer girder systems in high-rise buildings, focusing on their seismic performance using STAAD Pro. A ten-story building model was analyzed, considering key factors like lateral displacement, bending moment, and shear force. The study followed IS 1893:2016 standards and applied various load combinations to assess the building’s seismic response. Findings show that the transfer girder system performs better, with lower lateral displacements (10-28mm) and higher bending moments and shear forces, indicating superior stability under seismic forces. However, the transfer slab system remains a viable option, especially in cases where cost and design considerations are critical. The study emphasizes balancing seismic performance, structural efficiency, and cost-effectiveness when selecting a transfer floor system.
To analyze High Rise Building for Transfer Floor System with Transfer Slab and Transfer Girder subjected to Seismic forces. 1) Study of transfer floor system will be carried for transfer slab and transfer girder. 2) Analysis of high-rise building transfer slab and transfer girder system using structural analysis software. 3) Study the feasibility of building at different level for transfer floor system with respect to building height. 4) Comparative study of seismic behavior of two types of transfer floor system with transfer slab and transfer girder.
Key Words: Seismic analysis, High-rise building, Transfer slab, Transfer girder, Comparative analysis, Seismic forces.
2. Literature Review The literature review highlights the effects of a soft storey mechanism forming below the transfer level in high-rise buildings, as well as the impact of abrupt structural changes near the transfer storey. It points out that there is limited research available on the analysis of high-rise buildings incorporating a transfer floor, an important structural element used to distribute loads. The review emphasizes the need for further studies focusing on the vertical placement of the transfer system in relation to the building’s overall height. Additionally, it stresses the importance of a comparative analysis between two common types of transfer systems— transfer slabs and transfer girders—to better understand their performance and influence on building stability.
1. INTRODUCTION High-rise buildings are iconic representations of modern urban development, driven by the need to optimize limited horizontal space in cities. While these towering structures showcase architectural innovation and engineering advancements, they also introduce significant challenges in terms of structural integrity and safety, especially in regions prone to seismic activity. Seismic forces, generated by sudden ground movements, induce lateral stresses that can severely impact tall buildings. As these structures grow taller, their interaction with seismic forces becomes more complex, requiring detailed analysis to ensure stability and resilience. Transfer floor systems, often used to redistribute loads or accommodate varying column spacing, further complicate the design. These systems, while essential for structural efficiency, must be carefully integrated into seismic analysis to ensure that high-rise buildings can withstand lateral forces without collapse or excessive damage. Therefore, the incorporation of robust seismic design strategies is crucial to the safe and functional construction of high-rise buildings, especially when transfer floor systems are involved.

Contributions of researchers are presented as follows, Prof. P.S. Lande, Parikshit D Takale (2018) [1] “Analysis of high rise building with transfer floor”, International Research Journal of Engineering and Technology (IRJET) Introduction of the transfer floor in the lower part of the structure is better than having it is at higher location. For girder type of transfer system there is reduction in storey moment and storey shear values below the transfer level as compared to slab type transfer system. Girder type transfer system improves the global behavior of the structure. The displacement distribution shown in displacement graph reveals that every building has a flexural behavior mode up to its transfer floor
