Technical Articles

Simplified Blast Design According to AISC Steel Design Guide 26

Blast loads from high energy explosives, either accidental or intentional, are rare but may be a structural design requirement. These dynamic loads differ from standard static loads due to their large magnitude and very short duration. A blast scenario can be carried out directly in a FEA program as a time history analysis to minimize loss of life and evaluate varying levels of structural damage.

NBC 2015 Modal Response Spectrum Analysis and Base Shear Considerations

The National Building Code of Canada (NBC) 2015 Article provides a clear procedure for earthquake methods of analysis. The more advanced method, the Dynamic Analysis Procedure in Article, should be used for all structure types except those that meet the criteria set forth in The more simplistic method, the Equivalent Static Force Procedure (ESFP) in Article, can be used for all other structures.

Technical Articles

P‑Delta Effects and Seismic Design According to the ASCE 7‑16 and NBC 2015

As gravity loads act on a structure, lateral displacement occurs. In turn, a secondary overturning moment is generated as the gravity load continues to act on the elements in the laterally displaced position. This effect is also known as "P-Delta (Δ)". Sect. of the ASCE 7-16 Standard and the NBC 2015 Commentary specify when P-Delta effects should be considered during a modal response spectrum analysis.
