| Abstract | The investigation is conducted in this study on a more efficient modelling of shear walls
commonly found in tall buiidings subjected to lateral load. As the thickness of most shear walls is
small in comparison with he other two dimensions, a thin-walled finite element bas~d on the
assumed strain method, which was used successfully in modelling other types of thin-walled
structures, is adopted for shear wall modelling in this study. This element assumes all cross sections
to be undistorted while allowing the effect of shear lag and torsional warping. In consistence with
this assumption, only three ~ectional degrees of freedom are employed in common for edges of all
elements the same cross secfipn. This greatly reduces the overall size of the degrees of freedom and
increases the versatility of the element. The model therefore allows composite section, such as lift
cores, to be handled systematically.
In this study, various tests with shear wall parameters are conducted, with special attention
to the performance and the versatility of the present shear wall model. For verification, frame
analogy, and other analytical and practical methods formerly derived for specific types of shear
wall structures are used in comparison. The present model is shown to be effective for all
configurations of shear wall cross-sections, some of which may not be handled by the commonly
used thick beam model due to their complexity. |
