Abstract EN
In many high-rise buildings, architectural requirements may result in a variable configuration for the vertical structural elements between the stories of the building.
To accommodate such vertical elements discontinuity, a "transfer" floor conveying vertical and lateral loads between upper and lower stories must be introduced.
A drawback of the transfer floor is the sudden change in the building's lateral stiffness at its level: the structure becomes susceptible to the formation of a soft-story mechanism under moderate to severe earthquakes.
These buildings generally showed conventional elastic behavior for minor earthquakes but suffer extensive crack in the vicinity of transfer floors for major earthquakes.
However, for design purposes current numerical modeling of high-rise building adopts reduced stiffness for the vertical elements for strength analysis and full stiffness for serviceability and drift analysis: a tradition that needs to be verified.
A 3-D numerical model is built-up for a high-rise building with such vertical irregularities and analyzed using elastic response spectrum and nonlinear time-history analysis techniques.
The effect of transfer floors on the buildings drift is investigated where judgment for adopting a full or reduced stiffness for the vertical elements is scrutinized.
