In ASCE 7-22 (and 7-16), equation 15.4-6 is used to find the fundamental period of a non-building structure, and by its inverse, the natural frequency. It's a simple enough calc for the 10'x10'x5' braced frame structure I'm designing for a piece of equipment that requires a maximum 20Hz limit...
I'm designing foundations for large (tall) industrial tanks and I have two related topics that are not clear to me.
Using ASCE 7-16 for wind pressures, 29.4.2 gives criteria for when to consider tanks grouped, isolated, or when to interpolate the drag coefficient. However, there does not appear...
Does anyone have a design approach for a reduction to the MWFRS wind pressure if a cladding is used with a given percent openness that involves more than just reducing the pressure based on the percent open?
Here is the situation: We're designing a facility to be hardened for an extreme wind...
Hello. Long time, first time.
Until recently, I've understood that 3ksi and 4ksi concrete mixes were comparable from a price perspective. I had a design manager with a GC indicate that their pricing exercise may have been completed with 3ksi mix and using 4ksi would be an unnecessary cost. He...
