|Abstract:||<p>This thesis studies the behaviour of multi-storey wall-frame structures subjected to lateral and/or torsional loads. A planar structure with rotational and vertical restraints imposed between the wall and the frame is analysed. Parametric studies of a nominal structure are presented to examine the general effects of such restraints and structure height on wall-frame interaction. In the light of the understanding acquired from this two-dimensional analysis, a more general method of analysis for three-dimensional wall-frame structures is developed. For both methods, the variation of structural properties along the structure height is considered. A more flexible method of analysis for general three-dimensional building structures analogous to the stiffness matrix method is also presented. Applying this method to determine the structure stiffness matrix and using the lumped-mass approach, an attempt is made to study the free-vibration dynamic responses of the Banco de America Building both before and after damage was sustained by the building during the Managua earthquake of December 23, 1972. Lastly, conclusions regrading the behaviour and design of wall-frame structures are drawn, and the applicabilities and limitations of the three-dimensional analytical methods developed in this thesis discussed.</p>|
