2Project’s Outline Introduction PCI Big Beam competition rules and
criteria Pre-stressed concrete Preliminary design Timeline and work plan Reflections
3Introduction
Competition background
PSI: Pre-stressed Inc.
Capstone component
International and North American Teams
4Rules & Criteria Design accuracy
Material cost and weight
Max deflection at maximum specified load
Accurate predictions
5Project Methodology
The study of pre-stress concrete concept
Design concrete mixes for the pre-casted beams Different mixes for capstone purpose
Design of one concrete beam for the PCI competition
Design of two concrete beams for the capstone
Experimental testing and comparisons
6What is Pre-Stress Concrete?
Applying a compression force/stress before subjecting it to the actual loading
Major concept is the tendon stressing Pre-tensioning
Post-tensioning
Loads vary with time
7Losses
Immediate and time dependent
Two method used Simplified
