| Ringkasan: | A new connection device, based on bent-up tab shear transfer enhancement called bent-up
triangular tab shear transfer (BTTST), has been studied through a cold-formed steel
(CFS)-concrete composite beam subjected to a static bending test. BTTST provides an
alternative connector system unique to CFS where CFS sections are usually thinner than
hot-rolled sections and welding of headed-stud shear connectors is inapplicable. Coupled
with the back-to-back arrangement of two CFS channels where symmetricity of the built-up
section is restored, the resulting composite floor system has been proven to possess adequate
strength, stiffness and ductility properties under static loads. The work has shown specimens
employed with BTTST increase the strength capacities and reduce end slips of the specimens
as compared to those relying only on the natural bond between CFS and concrete. |
