|Title: ||Analysis and behaviour of transfer girder systems in tall buildings|
|Authors: ||Puvvala, Jawaharlal|

|Abstract: ||The structural behaviour and analysis of high-rise building components and supporting transfer girders have received added emphasis due to its importance in connection with modern tall buildings. Traditional theories consider such kind of structures as simple wall beams. Approximate formulas for estimating the behaviour of the supporting beam were developed. However, because of the lack of clear understanding of structual behaviour and analysis of transfer beams supporting various high-rise building components, approximate formulas are not widely used. In the present work, analysis and structural behaviour of supporting transfer girders supporting various high-rise building components like solid shear walls, coupled shear walls and rigid frames are presented.
Unlike normal deep beams, there is no particular span/depth ratio for estimating the structural behaviour and failure mechanism of transfer girders. The supporting transfer beam acts either as a full tension member, deep beam or as a ordinary beam in bending depending on the type of upper structure form and there relevant parameters such as span/depth ratio of the transfer beam, stiffness of the support columns, span of the shear wall and degree of coupling on the coupled shear walls, and etc. Detailed finite element analysis has been conducted using finite element code ABAQUS. Square plane stress elements were used to generate stress results. The selected finite element model was calibrated by applying to deep beams whose stresses are known. Realistic limits for span/depth ratios are defmed for transfer beams to act as a tension member supporting different upper structural forms. The interactive zone of the system in which distribution of the internal stresses are complicated has been indicated in the analysis. Conclusions of the invetigation are drawn from the structural behaviour, analysis and parametric studies.|
