Abstract

This paper reports the experimental results of symmetrical push-out tests performed on nails and screws connectors for natural laminated timber (Kempas timber) concrete composite floor systems. The characteristic shear strength and slip modules were evaluated for two types of connectors: Type (A) Nail connector with 73.37 mm length x 4.35 mm diameter; Type (B) Screw connector with 68.7 mm length x 5.47 mm diameter. The shear force, relative slip and slip modulus results were analyzed and design of TCC deck connectors were performed using the Gamma Method. The failure mechanisms of these two connectors type are discussed. Analytical design formulas for shear-strength evaluation of (nail and screw) connections derived in accordance Eurocodes are proposed based on four possible failure mechanisms. Good approximation was found if a slight modification of the Eurocodes formulas is introduced.

Keywords: timber, nail connector, screw connector, TCC deck
