ABSTRACT
A new deconstructable composite floor system consisting of precast concrete planks and deconstructable clamping connections is proposed to promote sustainable design of composite floor systems within steel buildings through comprehensive reuse of all key structural components. A pushout test setup has been developed to study the clamping connector behavior experimentally. Finite element analysis results are presented to investigate the strength and ductility of the deconstructable shear connectors and study the effects of the analysis parameters. The scope of the project also includes beam and diaphragm tests to study the flexural and in-plane behavior of the structural system.
