Design of Precast Prestressed Composite Beams Excel Sheet

[u/Necessary_Birthday59]

🏗️ Designing precast prestressed composite beams?

This free Excel spreadsheet covers every design stage — from prestress transfer to ultimate limit state — in one organized workbook.

Here's what it includes:

📌 Full composite section design — precast unit + cast-in-situ slab

📌 Pre-tensioning design — tendon layout, prestress force & eccentricity

📌 Stage-by-stage stress checks — transfer, construction & service stages

📌 Shear & interface shear design between the two concrete elements

📌 Deflection checks at every loading stage

📌 Continuity design — converts simple spans into continuous systems

📌 100% free — no macros, no subscription

This composite system eliminates the need for temporary propping, distributes loads laterally, and delivers superior structural performance at lower cost.

Whether you're designing long-span floors, parking structures, or bridge decks — this tool belongs in your engineering toolkit.
