AEDO Construction Learn
Structural engineering explained the way we check it on real AEDO designs: the question, the answer first, then the reasoning with diagrams you can move, the governing NSCP 2015 clause quoted and cited, and the actual numbers.
Cantilever Columns or Portal Frame?
Seated trusses or moment joints? How NSCP Table 208-11B classifies a covered court or shed, the roof diaphragm flexibility test (208.5.1.3) and accidental torsion (208.5.1.4), with four options compared on one real shed.
NSCP 2015 Sec. 202, Table 208-11B, 208.5.1.3, 208.5.1.4 Read the explainer → FoundationsWhich way does the footing turn?
Why an edge footing against a lot line grows along the line, not across it: P·e, overturning under 0.6D + 0.6W and the 0.45 B limit, plus the rule for concentric pads. Interactive plan with real numbers.
NSCP 2015 Eq. 203-14, 203-15, Table 304-1 Read the explainer →How these are made
Each explainer starts from a design question the AEDO team answered on a real project. The numbers come from that project's own analysis model, the client and site details are left out, and every quoted clause carries its NSCP 2015 section and page so you can check it in your own copy. New topics are added as new kinds of projects come through.
