It is my understanding that the concrete contractor will build from the rebar place (shop) drawings and not the structural drawings. We have a project where the rebar shops don't show a lot of information (like spread footing locations and wall elevations) and the rationale is that the...
Concrete was poured at a shear wall at about 110 minutes. According to ASTM C-94, "The discharge of the concrete shall be completed within 1 ½ hours after the introduction of the mixing water to the cement and aggregates, or the introduction of the cement to the aggregates." Any thoguhts on...
I am looking to learn how to use Revit Structure to draw details. I have been watching videos on Youtube, but many of them assume some knowledge of Revit. Do you know of good videos on line that explain the basics of using Revit particularly for drawing details?
Thanks
I did a back check of the bending moments and shears for the beams and found that the moments in the PT designer's calcs are much smaller. I used a simple program to find the moment for multi-span beam and my numbers are significantly higher. The PT engineer thought that the pt caused the...
I am reviewing post-tensioned concrete slab and beam shop drawings and calculations. It is my first time. What advice do you have on things to look for?
This is for users of the CFS program by RGS Software for cold formed steel member design.
In the member check menu, the user is required to input the axial loads, moments and shears. Must the maximum shear and moment be used even if they do not occur at the same location?
Thanks.
I need the PDC Technical Report 10-02. It is my understanding that they updated it in April of this year, but now it is no accessable from the PDC web site.
Can anyone post a copy or email it to me?
I spoke with the Hilti engineer, and he sindicated that the self tapping screws would work when drilled from above. He recommended using 14 gauge or 12 gauge material.
I need to determine what screws should be used to connect a 5/16” plate to light gauge rafters and roof trusses. See the attached sketch. The wind uplift is around 80 pounds/foot. The 5/16” bent plate will support a gutter, which will weigh 16 pounds/foot if full of water. The building is in...
