Problem 2
Part A
The analytical model (MASTAN) of this structure had assumptions. I assumed that there it is a 1 st
order elastic analysis of a planar frame. This was assumed so that the structure wou

Question 1
(a) The midspan vertical displacement from the truss model of the
Cooper River Bridge is 1556 inches downward (or 129.67 feet). The

Problem 1 Explanation of Results
Idealizing the bridge as a truss, we need to check for its static determinacy. If the
bridge is not statically determinate as a truss model, for learning purposes, we

Procedure
We did not deviate from the procedure specified in the lab manual. Gauges 1 and 2
are full bridges and gauges 3, 4 and 5 are half bridges. Remember to take this into
account when doing calcu
