| Summary: | An experimental program was conducted to study the strength and behaviour of a bent-up
tabs shear transfer enhancement. Sixty eight push-out test specimens of cold-formed steel
lipped channel sections (CFS) embedded in concrete plank where by usage of a new
proposed shear transfer enhancement called bent-up triangular tab shear transfer (BTTST)
was used in this program. This paper summarizes the results of develop an expression in
order to predict the innovative shear transfer enhancement mechanism BTTST in a new
type of precast composite beam comprising Cold-formed steel (CFS) embedded in precast
concrete plank. The results show that the proposed equation is in good agreement with the
observed test values. The average absolute difference between the test values and
predicted values was found to be 8.07%. The average arithmetic mean of the
test/predicted ratio (μ) of this equation was 0.9954. The standard deviation (σ) and the
coefficient of variation (CV) for the proposed equation were 0.09682 and 9.7%,
respectively |
