| Abstract | Multistory tall buildings in general carry lateral loads through combined bending and horizontal shear actions. In this study, free vibrational characteristics of tall buildings are investigated with respect to the relative influence of bending and shear deformations. Periodic ratio between the first two modes is found to indicate the degree of shear distortion in building. Existing Cheung's finite strip model represents tall building displacements by free vibration cantilever beam functions. It is found in this study that the model can be ineffective for tall buildings in which shear distortion is significant. A wider class of orthogonal polynomial functions is presented and shown to be applicable to the full range of multistory buildings. Three different finite strips are developed, namely, column strip, spandrel beam strip and plane-stress strip. These strips are used for modelling various multistory building components. Numerical results indicate that the present finite strip model performs remarkably well for all situations, in both static and free vibration analyses. |
