Preview § Introduction § Computer Methods § Results § Conclusions
Introduction § Redundancy in Bridges § Definition § Reasons for Redundancy § Diaphragms
Introduction § Purpose § Previous Research on Redundant Systems § Cost § Examples of Non. Redundant Systems § Mianus River Bridge § Hoan Bridge in Milwaukee, Wisconsin § Silver Bridge in Ohio Hoan Bridge Milwaukee, Wisconsin, Before and after failure
Computer Methods n Finite Element Modeling n Risa 2 D n n Two Dimensional Computer Program Sap 2000 n Three Dimensional Computer Program
Project Parts § Part 1: Models of the bridges are tested using Risa 2 D § Part 2: The best representative model(s) are analyzed in Risa 2 D § Part 3: A model similar to the best representative model found in Part 2 is done tested in Sap 2000
Methods Part 1 § Working with Risa 2 D § Horizontal Bracing § Cross Bracing § Loads § Reasons

Results n Deflected Shape
Results § Deflected Shape
Conclusion § Horizontally versus Cross Braced § A horizontally braced frame has a more uniform load distribution than a cross braced frame. § Future Work § Continuing with Sap 2000
