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
