I want to place an eccentric distributed load on a beam in Risa 3D in order to induce torsion in the beam. It doesn't seem that Risa 3D accommodates this. Can anyone confirm? Thanks!
Hello,
I'm looking for information about stepping a PT slab. This would occur at a column gridline, and both the top and bottom of slab would step. Slab is generally 11" thick. I would appreciate any guidance on special design/detailing considerations at the step, whether special attention...
In a previous company I worked for, we had a curved concrete retaining wall that we created a 3D model for (I believe using Staad), that resulted in a much more economical design (similar to what you are describing). If you have a little time, you might try that.
I would like to demonstrate to my boss that a steel deck diaphragm can be supported with shear walls on 3 edges for a partially enclosed structure. In the past, I have done calcs to show the diaphragm deflection small enough to make this assumption (using wl^2/2 rather than wl^2/8 in the...
I have a project in which I am using the 2000 IBC, and am using the 2002 version of ACI 530 for masonry design. I cannot seem to find the half-stresses provision for designing without special inspection that was given in the 1997 UBC section 2107.1.2. My question: is special inspection now...
I have a question regarding the Beta(d) factor in chapter 10 of ACI (specifically, section 10.12.3). The code states that Beta(d) is the "ratio of the maximum factored sustained axial load to the maximum factored axial load". Can someone clarify what the "sustained axial...
