• Centroid Stress Plan inaccurate compared to hand calc P/A

    For context working on a 8in PT slab. In the banded direction in my interior bays I have 24 strands (26.8 kip/strand) for a trib width of 29 ft. Thus I have a stress of 230 psi (24'*26.8kip/ft / (28'*12*8")). When I look at Centroid stress plan under…
  • Trimming Design Strips: Ram Concept 2-Way PT Slab

    Given the layout of strips, in odd configurations due to irregular structural geometries, is it in y'all's opinion reasonable to review the original strips for any code-related failures (i.e. shear or tension) and make the proper adjustments to the PT…
  • 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 - Beam Torsion

    "As Shear" is appropriate for situations where the torsion is primarily caused by vertical shear eccentric from the "shear core" of the cross section (for a typical cross section with a beam, the "shear core" is the beam cross section). "As Shear" will…
