After much searching I finally found instruction that the intent of 9.3.4.2.3 c) is to specify a minimum area of shear reinforcement per segment of beam equal in length to the beam's depth. Thanks for the responses everyone.
Section 9.3.4.2.3 c) states that the transverse reinforcement (stirrups) must be at least 0.0007 times the beam cross-sectional area. But the stirrups are oriented vertically parallel to be beam cross section. If Section 9.3.4.2.3 c) were referring to longitudinal reinforcement, it would make...
So the question becomes "How is the section defined?" The transverse shear reinforcement is vertical and does not cross the section defined by (b)×(dv).
Section 9.3.4.2.3 c) of the 2013 MSJC Code (ACI 530-13) states "The minimum area of transverse reinforcement shall be 0.0007(b)(dv)." What "area of transverse reinforcement" is this section referring to? For a beam scenario, would that be the total transverse reinforcement area throughout the...
In the book Concrete Construction Engineering Handbook (edited by Edward G. Nawy) I found in Section 28.9.2.4 the statement:
"Due to the large quantities of prescriptive horizontal reinforcement, control joints are typically not necessary for special reinforced masonry shear walls"
Being...
While I can't argue that stabbing is bad practice. I can tell you that in my area it is standard practice on small stemwall footings.
The building official was basically asking me if I knew of an "out" for him.
As you can imagine, he is not at all excited about the long, nasty job ahead...
Does Section 1907.5 of the 2006 IBC Code prohibit the wet-stabbing of Stemwall verts into concrete strip footings. A local building official thinks that it does. Personally I think the section is intended to address only primary reinforcement but I may be wrong.
Does anyone have any...
I am providing structural design for a single-family residence in which some adjacent exterior walls are entirely glazed and offer no shear resistance. Treating the roof as a rigid diaphragm may be an inexpensive way to accomodate the open exterior walls. Are there any methods that may be...
