Introduction

This lesson covers Pattern Loading, explaining how the user can distribute live and snow loads on multi-span beams. When enabled, Sizer automatically generates all possible load patterns and designs for the worst-case scenario, ensuring compliance with NBC 4.1.5.3 and NBC 4.1.1. The program systematically turns live or snow loads on and off in different spans to create critical load combinations, affecting shear, moment, deflection, and uplift analysis. Pattern loading is essential as it can influence beam failure under certain conditions, even with the same load magnitude.
