For this week's beam analysis, I chose to analyze the three main beams that support the shed roof over the central portion of my atrium. Since these beams work together in a system, I thought it would be interesting to perform an analysis on each one individually as well as the system as a whole. Each beam spans a total of 80 feet, with a structural column at the 30 foot mark on each beam to support the system, as well as provide framing for the staircase on the west side of the building.
A special challenge I had was that the building incorporates a shed roof as a central feature of the atrium space within the exhibition space. I had to calculate the slope of the upper beam system, but having the upper beams at an angle might actually be stronger since the upper beams are at less than a 90 degree angle. I don't have the RAM space on my laptop to install separate analysis software, but I'm excited to see the results during this week's check-in.
I expect the beam sizes will leave sufficient space for my HVAC design elements for next week's module. However, if there isn't enough space I can reconfigure some of the smaller beams that don't support such heavy loads.
