Analytical Investigation of Floating Panel System for Seismic Resistant Precast Building Structures

Abstract

Precast concrete structures are gaining popularity due to its lesser construction time and easy constructability in the modern era. These structures are usually long span with the shear walls at the edges for a lateral support. Even though the diaphragm design forces have increased, researchers and practitioners agreed that more research on the seismic behavior of the precast concrete structures is needed. This dissertation proposal proposes an innovative connection technique in the precast concrete structures. The primary objective of the dissertation proposal is to show the performance effectiveness of the proposed system during a seismic event. To accomplish this, two- dimensional (2D), and three-dimensional (3D) numerical models of the diaphragm with shear walls have been developed using a Finite Element (FE) analysis program, ANSYS. A suite of ten spectrums-compatible earthquakes with different frequency contents are subjected to the FE models. The effective response of the proposed system is being studied.
