Review of Existing Precast Concrete Gravity Load Floor Framing Systems

Abstract

This paper reviews 19 precast structural floor systems from North America and overseas that are suitable for office building construction. This review includes a discussion of the impact of the structural systems. The review was conducted as part of a research project directed towards the development of new precast concrete floor systems for gravity loads for application in occupied office buildings having a regular spacing of columns. A companion paper presents the assessment of these floor systems. The research addresses the need for innovation in the design and construction of precast concrete buildings.
