2019年2月8日 · Having trouble understanding steel beam references on construction drawings? We explain what all those numbers and acronyms mean. 1. 'Open' Steel Sections. (Universal Beam [UB] Universal Column [UC] and Parallel Flanged Channel [PFC]) Nominal Size vs. Actual size of open sections.

Explore the area moment of inertia (second moment of area) with detailed formulas, calculation tools, and reference tables for common shapes. Essential for structural and mechanical engineering applications. Calculate beam load and supporting forces. Supporting loads, moments and deflections. Stress, deflections and supporting loads.
