Hi, Based on NBCC 2015 4.1.8.11 4) single storey buildings with steel or wood deck as diaphragms can have a higher fundamental period compared to 4.1.8.11 3) as seen in the snap below. However, in the current RAM frame the Ta is only based on clause…

I'm getting some conflicting graphical information and output. I'm designing a special concentrically braced frame (SCBF) with wide flange beams and columns and HSS braces. The frame column webs are oriented in the plane of the frame and all beam and…

I am looking at the requirements of the beam at the second story of the chevron BRBF. Why is RAM Frame checking Beam ductility using the Diagonal Brace requirements of AISC 341-16? The output clearly says it does not check the axial demand in the beam…

Hi, I wanted to clarify the output for the seismic provisions joint code check in regards to continuity plate. I am unclear of what the 0.66" under "Tf Prov (in)" is indicating. Do I need a 0.66" thick continuity plate? Also, how is RAM arriving at…

Hi! I'm a plan reviewer with the city of San Jose. I'm reviewing a new hockey arena and I have some questions about how RAM processes automated ELF procedures and seismic drifts for structures that have collector columns. It's a BRB building, but thin…

Hello all, I'm an undergraduate modeling a 5 story building in RAM Structural System for a structure class. I have several basic issues: 1. Load inputs: Snow = 30 psf, LL = 100 psf, DL = 3000 kips QUESTION: Do I differ the loading between Floors…
