Effects of Shear Studs and Openings in The Mechanical Performance of Composite Floor Deck using Finite Element Analysis

Abstract

The composite floor deck system is the most popular floor system used in the construction industry, especially in industrial structures. A composite floor deck is a floor system that consists of a steel deck bonded with concrete. The shear bond between the steel deck and concrete slab normally controls the shear capacity of a composite floor deck system. In the current construction industry, shear studs are normally used to improve the shear performance of the structure. However, the literature review shows that there were very limited studies on identifying the efficiency of these shear studs and their effects on the composite floors' mechanical performance. In addition, there were always openings for M&E equipment in the floor deck system, which needs further analysis to determine their effects on themechanical performance of the composite floor deck system. Thus, the main objective of this study was to identify the effects of shear studs and openings on the mechanical performance of composite floor decks. The method adopted in this study was the Finite Element Analysis (FEA) using ANSYS software. The outcome of the result has shown that the presence of shear studs improves the mechanical performance of a composite floor deck while the presence of openings reduces the mechanical performance of a composite floor deck system.Keywords: composite floor deck, opening, shear studs, mechanical performance
