Title: Behavior of bond Under Dynamic Loading
Author(s): Robert J. Hansen and Atis A. Liepins
Publication: Journal Proceedings
Appears on pages(s): 563-584
Abstract:Bond strengths of standard deformed reinforcing bars under static and dynamic loadings have been investigated under conditions in which splitting failures have been inhibited. The tests have shown that local static bond strengths may be as high as 0.75fc' and that under single pulse dynamic loading at high strain rates this strength increases to fc’. For all practical lengths of embedment of bars steel failure may be expected under both static and dynamic loading. Such bars loaded dynamically will carry a larger load than bars loaded statically, this increase in carrying capacity being due solely to the increase in steel strength under dynamic loading.
