RAM Concept Shear Reinforcement Section Design
Hi,
I'm trying to get a deeper understanding of why RAM Concept is showing my shear requirement as being larger than the same beam I have modelled in RAPT to verify. RAPT does not require any additional shear reinforcement. I have checked the shear…
Shear in PT beams when Design column strip for Column + Middle strip resultants is checked
Hi there,
I'm designing a parking PT slab with PT beams in a corner panel where we have higher loads. I noticed that the amount of shear reinforcement in the beams running parallel to the distributed tendon (longitude direction) increases exponentially…
RAM Beam Shear Reinforcement Output in Slab Span Direction
Hi,
I've come across this particular issue a number of times but have never had RAM specify this much shear reinforcement before - see snapshots below. This is a one-way slab and band beam system so wouldn't be expecting shear ties in the beam like…
1 way shear effective depth calculation
I have an existing two-way slab that I am trying to analyze. At locations of negative bending, the effective depth for one way shear calculations is much smaller than I'm calculating it to be by hand.
Based on the value that the audit is showing, it…
RE: Ram Concept- Shear Reinforcement
If you look closely at the section audit for a section from each case and compare them side by side it's a little easier to tell what is most significant. Below is a table of just a few lines from the audit to help you, ultimately is a small change in…
RE: Vertical Shear Contour Plot in RAM Concept
I would normally recommend plotting Slab - Shear - (Mid depth) Max (and Min) for this, though you will get a warning like this for any Rule Set:
--------------------------- Slab Plot Accuracy ---------------------------
The selected slab plot may…
RE: RAM CONCEPT: Shear reo in slabs according to AS3600-2009
You might find the section design plot for "Shear Density" to be informative. In the case os your right middle strip, the shear demand is indeed quite small, but a plot of Strength Design - Shear density indicates ties are required at several stations…
RAM Concept Shear + Torsion and Tabular Input
Hello again.
I was adding some user shear reinforcement to a model recently (hurray for this being a feature now), and had some things happened that piqued my interest. I started digging around in the audit report to better understand how Concept is…
RE: RAM Concept Reinforcement Detailed Bars Perspective
On the design status layers, the tick marks for the shear bars are a bit symbolic. They are typically placed along the span segment line and spaced based on the design. See manual section 29.5.4 "Shear reinforcement" for details on this kind of output…
