Bridge Forces Executive Summary 1. Problem Statement: In this case, I was tasked to analyze a truss system. The main focus of this analysis was to inform a general contractor whether a model for a particular bridge was oversimplified. The contractor was worried that the model for the bridge was oversimplified because it neglected the member weight. In the first part of the problem I was required to analyze the structure by neglecting the member weights, but adding a simulated truck load on the bridge. In the second portion of the problem, I removed the truck weight and analyzed the bridge using the actual member weights. In my problem, the member weights were 850 lbs a piece and they were each 17 feet long. 2. Assumptions: The first step I had to take to analyze this bridge was to make a few initial assumptions. First, I assumed that the truss was loaded only at the joints. I also assumed that the members were joined by frictionless pins. In the first part of the problem, I also had to assume that the member weights were negligible. I also assumed that the load (P) was all at member, forces, weight, weights, problem, load, bridge, part, force, members, first, truck, one, analyze, neglecting, calculated, assumed, appendix, using, terms, second, quattro, pro, portion, model, lbs, general, each, contractor, both, appendices, whether, values, truss, tensional
