CELE Structural Theory & Analysis — Deflections of StructuresSlides
Revision slides for CELE Structural Theory & Analysis — Deflections of Structures. Structured for quick scanning, with one idea per slide and the key formulas called out clearly. Good for the final week before the CELE 2026 when you want to refresh the whole chapter in under an hour.
Exam context
For the Civil Engineer Licensure Examination, Professional Regulation Commission (PRC) — Board of Civil Engineering tests Structural Theory & Analysis under a "Core" label, with Deflections of Structures in the 2nd slot across 6 chapters. CELE candidates must clear the 70% weighted average, no sub-test below 50% cut on the 2026 paper, which draws about a meaningful share of Structural Theory & Analysis questions. Date to watch: May and November 2026.
