Dynamic Analysis of Seismic Response in Structures Incorporating Lower-Storey Transfer Systems

Abstract - In contemporary construction, increasingly complex and variable architectural planning requirements often hinder the vertical continuity of columns from the foundation to the top storey. This discontinuity necessitates the introduction of a transfer storey to accommodate vertical irregularities in the structural system. To effectively channel the substantial loads from upper storeys to the foundation, structural elements such as transfer slabs or transfer girders are implemented. These components form a critical part of the load-transfer mechanism in high-rise buildings. However, their inclusion introduces significant structural challenges, requiring advanced analytical approaches and a deep understanding of structural engineering principles. This study focuses on evaluating the key structural parameters of multi-storey buildings with and without transfer levels through both static and dynamic analysis. Transfer structures represent one of the most complex aspects in the design and execution of high-rise construction. Key Words: Transfer floor, transfer girder, dynamic analysis, static analysis, vertical irregularity, high-rise structures.
