|Abstract:||With the advent of high-speed computers and the increasing emphasis on numerical methods, finite element method of analysis has been applied to a wide variety of structural engineering problems, especially to core walls in tall buildings. This dissertation studies the analysis of core wall structures by finite element method. The study comprises three parts. The first part covers analysis of experimental models and model structures studied by previous authors and researchers. The results obtained are compared with theoretical and experimental results, and with the results from wide column frame method. It is found that finite element analysis gives more accurate results on rotational displacements than the wide column frame method. However, both methods give fairly close results on translational displacements. The second part covers the results of a comparative study on the analysis of a practical sized core wall by the finite element approach and the wide column frame approach. The study also indicates that the finite element analysis produces more accurate results on rotational displacements than the wide column frame method. The last part of the dissertation examines the interaction between floor slabs and the core in resisting lateral loads using finite element techniques. It is found that contribution of the floor system together with the perimeter frame in reducing the translational displacements and torsional rotation of the core is significant. However, the slab thickness has little effect on both the deflection and rotation.|
