1 “It’s All Fun and Games Until the Parking Garage Collapses” CASE STUDY: 2003 Tropicana Casino Parking Garage Collapse

2 Reinforced Concrete Matrix- concrete Can withstand high compression Relatively low tensile strength – Compressive strength : MPa ( psi) 1 – Tensile strength : MPa ( psi) 1 Reinforcement- rebar Steel bar Relatively low compressive strength High tensile strength – 70, ,000 psi 2 1.http://www.engineeringtoolbox.com/concrete-properties-d_1223.html 2.http://www.webcivil.com/usrcrebar.aspx

3 Composite Properties Concrete provides compression strength Rebar provides tensile strength Why is it important to have both? Image from

4 Ways Reinforced Concrete Can Fail Image from 1.html

5 2003 Tropicana Parking Structure Collapse Keating Construction Company of Philadelphia heading project – Subcontracted to Fabi Construction Company of Egg Harbor, NJ Emphasis on speed of construction rather than safety Part of the structure collapsed while worker was pouring concrete 4 workers killed, over 20 injured Company fined $119,500 by OSHA $101 million settlement paid to the families of those injured or killed https://failures.wikispaces.com/Tropacana+Casino+Parking+Garage#IV.%20CAUSES%20OF%20THE%20FAILURE

6 Challenge- Why Did the Structure Collapse? Split into groups of 4-5 people Elect a spokesperson Spend minutes hypothesizing why the structure fell based on images provided, as well as what you know Report your conclusions to the class

7 Reasons for Failure Rebar mesh used instead of rebar rods – Not a problem, except that the mesh was not laid far enough into the columns – Rebar mesh “ripped out” of columns Insufficient stabilization of drying concrete – Wet concrete is significantly heavier than dry concrete – Metal rods used to hold up drying concrete bent https://failures.wikispaces.com/Tropacana+Casino+Parking+Garage#IV.%20CAUSES%20OF%20THE%20FAILURE
