| Abstract | Hypothesis: Structural lateral drift and torsion typically play a deciding role in the design of tall buildings. When the lateral force occurs along the asymmetric axis, structural deformation tends to be amplified. ❧ The focus of this thesis is on the study of how the sectional geometry and configuration of a steel-frame building may affect its deformation response to seismic and wind lateral forces. ❧ The light-weight and ductile, tall, steel-frame building has become a dominant architectural form in high-density urban areas, especially high-seismic zones. However, the construction of such structures brings its own unique challenges. One essential issue involves deformations of the structural system in response to seismic and wind loads. The taller the building, the greater its mass (seismic concern) and building surface (wind load concern) will be. The resulting larger lateral forces will in turn lead to greater deformations. Lateral seismic and wind forces represent the most critical design issues for tall buildings. These forces are dynamic, with magnitudes and directions that, by their nature, vary with time and are highly unpredictable. ❧ This thesis focuses on the behavior of a steel-frame building with certain sectional geometries and configurations (symmetrical versus asymmetrical) in response to seismic and wind forces and whether the sectional deformation involves local and global rotations. Shake-table tests and computer simulations of the various deformations were used to confirm the findings and the conclusion as well as to aid in the study of design improvements. |
