Re: Commercial Bldg. - Second Floor Loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]

You're so mean!  It's like you know everything!  You know what,  I acted the same way when I was fresh from college.  I was so confident that I thought I know everything.  I look people who are not smart with disdain.  As I matured,  I learn to accept that I don't know everything and sometimes you learn from people who you think are dumb.

Maybe you are still a new engineer to act that way.

This isn't rocket science buddy.  Determining the floor load for mezzanines is pretty basic stuff.  Sure, engineers will have different schools of thought on how to precisely interpret the floor loading requirements.  But when it comes right down to it we all follow an almost identical, logical approach on how a floor will be loaded up.  If this was my project I'd be spec'ing the joists for 80+20, and designing the beams for a reduced 80 and an unreduced 20. That's usually what an architect means when they say the want 100 psf LL.  In fact I would bet that 95% of the office space in the U.S. isn't designed for anymore load than this.

The purpose of my "crack" is to hopefully wake you up.  Like I previously implied, your thought process is irrational.  There are many other aspects of designing mezzanines that are quite a bit more complicated than this.  If your having trouble with this concept, I'm not convinced your going to fair very well with the rest of your design.
