    Missing Compression properties of ASTM 572 Gr 50 Structural I-beams

    All, Upon reviewing the property cards for a Gantry analysis I was interested to see that the compression properties for the I-beam material were assumed to be the same as the tensile properties (i.e. not specified). Searching MatWeb for the material properties yielded many results such as for...

    Gantry Seismic Analysis

    Thanks for your interest, For this part of the analysis review I want to consider just seismic considerations. The modeling so far does not address the possibility and I wonder what the appropriate loads and boundary conditions would be. Note that the Gantry system is stationary, mounted in...

    Gantry Seismic Analysis

    Good Day All, I am looking for a checklist of items to review for the seismic analysis of a gantry system. In modeling the structure I believe that in addition to load factoring of the static loads and boundary conditions there also needs to be a buckling run and a modal analysis. Can I humbly...
