Title: A Study Of Reinforcement In Concrete Slabs
Author(s): Inge Lyse and George R. Wernisch
Publication: Journal Proceedings
Appears on pages(s): 1-16
Abstract:Presentation is made of the results of an investigation of the use of different types and, grades of reinforcing steel in 4 in. thick and 34 in. wide concrete slabs of various length and with different strengths of the concrete. The steel developed its full yield-point strength when flexure governed failure; increasing the strength of the concrete did not materially increase the effectiveness of the reinforcement. The reinforcement was as effective in 16-ft spans as in 5-ft spans; size and spacing of steel did not influence the strength of the slabs; ordinary deformed reinforcing bars were as effective as welded wire fabric; and when reinforcement was stressed to 30,000 psi only hairline cracks appeared in the slabs and these cracks wholly disappeared when the loads were removed.
