| Summary: | The LVL-concrete composite (LCC) structure is a hybrid in system which the LVL
member is well connected to the concrete slab by a connector to produce composite action. Various
types of connector with different stiffness and shear capacity are available in the market currently.
The stiffness of the connector is identified through the push-out experiment. The notch connections
for LVL concrete composite beams have higher stiffness and strength compared to mechanical
fasteners. This paper discusses the experimental results of symmetrical push-out tests on 3 different
types of connector, 150 mm rectangular notch with 10 mm diameter screw, 100 mm rectangular notch
with 8 mm diameter screw and 100 mm triangular notch with 8 mm diameter screw. The experimental
test was shear push out to failure and the type of failure was discussed. The 150mm rectangular notch
was found to be strongest among all and low cost. The 100 mm rectangular notch was found to be
slightly stiffer than 100 mm triangular notch but 100 mm triangular notch is easier to construct with
only 2 cut. The maximum strength and stiffness at ultimate limit states and serviceability limit states
of each type of connection were discussed in this paper |
