This paper reports the experimental results of symmetrical push-out tests performed on notched and toothed metal plate connectors for laminated veneer lumber ͑LVL͒-concrete composite floor systems. The characteristic shear strength and slip moduli were evaluated for three types of connectors: ͑1͒ a 300-mm-long rectangular notch cut in the LVL joist and reinforced with a 16-mm-diameter lag screw; ͑2͒ a triangular notch reinforced with the same lag screw; and ͑3͒ two 333-mm-long toothed metal plates pressed in the lateral surface of two adjacent LVL joists. The shear force versus relative slip relationships are presented together with analytical prepeak and postpeak approximations which can be used to carry out nonlinear finite-element analyses of LVL-concrete composite beams. The failure mechanisms of the notched connections are also discussed. Analytical design formulas for shear-strength evaluation of notched connections derived in accordance with New Zealand Standards and Eurocodes are proposed based on four possible failure mechanisms. Good approximation was found if a slight modification of the Eurocodes formulas is introduced.

“…In contrast to concrete structures, TCC structures are highly energy efficient and can significantly reduce CO2 emissions through a carbon sequestration mechanism, as timber is a carbon store (Rodrigues et al 2013). These features are the advantages of timber-concrete composite structure (Lukaszewska 2009). In China, the importance of environmental protection is increasingly realized and the use of TCC will probably become extensive also in China.…”

The key point of design for timber-concrete composite structure is to ensure the reliability of shear connectors. This study examined the mechanical properties of bolt-type connectors in timber-concrete composite structures theoretically and experimentally. The theoretical study was based on the Johansen yield theory (European Yield Model). Push-out specimens with different bolt dimensions were tested to determine the shear capacity and slip modulus. According to the experimental results, bolts yielded without timber or concrete cracks when the stiffness of bolts was not very great. The shear capacity and slip modulus of the bolt connectors were directly proportional to the diameter of the bolt. The strength of concrete was found to significantly affect the shear capacity of bolt connectors. Comparison between the theoretical and the experimental shear strength results showed reasonable agreement.
