On the Applicability of Fixed Point Theory to the Design of Coupled Core Walls.
Master's Thesis, University of Pittsburgh.
(Unpublished)
Abstract
Coupled core walls offer an efficient lateral load resisting system. Due to their exceptional stiffness (many times greater than the sum of the component wall piers), coupled core wall structures are especially attractive in earthquake-resistant settings. Current design practice does not address dynamic properties of the structure, in particular the optimization of the coupling beams. The coupling beams affect both the "static" (stiffness) and dynamic performance of the structure to varying degrees depending on their damping and stiffness properties. Fixed Point Theory is applied to find optimal damping and stiffness values for beams coupling two wall pier structures. In this initial investigative work, "performance" is defined in a novel way: as the practical minimization of transmissibility of horizontal ground motion. An initial parametric study applies fixed point theory optimization to a series of 84 sets of wall piers. From this parametric study, two prototype structures are advanced and analyzed using linear time history analyses to assess their performance in a simulated earthquake. These "optimized" structures are compared to practical, uncoupled, and rigidly linked systems to determine the validity of the application of Fixed Point Theory to the choice of coupling beam properties.
