| Abstract |
This study shows the implementation of material topological optimal design in order to investigate structural functions of frame-shear wall systems with outriggers. The system has been often utilized in order to reduce horizontal displacements by wind loads in high-rise buildings. Since the topological optimal design can determine topologies and shapes with maximal stiffness with respect to a given material, it can estimate structural mechanisms of the frame-shear wall systems which depend on the number and location of outriggers. In this study a density distribution method are applied for the material topological optimal design. A simple cantilever beam is numerically assumed to be a high rise building. The numerical applications for topologically optimizing the cantilever beam demonstrate the outrigger's structural effect in high-rise buildings with frame-shear wall systems. |
