Sep 21, 2006 · The situation is a concrete retaining wall that is supported on rock and I am trying to justify decreasing the width of the foundation by tying into the rock with grouted rebar to take up …

Jan 16, 2002 · Are there any guidance on development length of reinforcement in shear? ACI defines requirements for tension and compression, but not for shear.

Aug 3, 2016 · Does anyone know of an interaction equation for tensile and shear force on a rebar? The bar is being used to resist a force through it's tensile capacity, which is developed with the proper ld. …

Feb 28, 2017 · The shear strength of rebar is not a factor in concrete design. The bearing or crushing of the concrete in dowel action always controls. This is probably the reason codes don't define the …

May 17, 2001 · In their 2016 post installed rebar design guide, Hilti covers dowels for shear friction based on a paper by Palieraki (attached). It's a hybrid dowel/shear friction method that seems to …

Mar 7, 2013 · Many of the designs I have seen use #3 at 16" OC horizontal for both CMU and CIP shear walls. However ACI 530 and ACI 318 both list minimum horizontal reinforcement that seem to require …

Feb 12, 2025 · I have a couple of questions on one of the provisions that has been added in ACI 318-19. The clause on 17.1.6 states: Reinforcement used as part of an embedment shall have development …

May 20, 2003 · The toleraces due to aggregate size, minimum concrete cover, min req'd spacing in relation to your rebar size, min required steel area per cross sectional area of concrete must be …

Aug 18, 2008 · I have checked an existing concrete beam, Its shear capacity is not enough, and there is no shear reinforcement(i.e. no tie rebar), But its flexural capacity is over kill and it has an extra layer …

Feb 11, 2002 · I think that the shear strength of a steel bar in a concrete-masonary interface will seldom be the controlling factor. Under load the steel will tend to deform to an S-shape as the concrete …
