1. ABridge company hires you to help them size the members of the bridge shown in the ‘accompanying figure for a case in which traffic is backed up with a total of four trucks equally spaced on the bridge. A typical truck has a payload of weight of 65,000 Ib and a cab weight of 7800 Ib. As a starting point, you may use one cross-section of all the beam elements. You may assume one cross-section for all truss members. The roadbed weighs 1500 Ib/ft and is supported by I-beams. Use standard steel I-beam sizes. Design your own truss configuration. In your analysis, you may assume that concrete column does not deflect significantly. Write a brief report discussing how you came up with the final design.

Designing of a truss configuration:
Truss: A structure is said to be a truss if it "only consists of components with two forces" and if those members are grouped in such a way that the assemblage as a whole "behaves as if it were a single item." A structural component is said to be a "two-force member" if it only has two sites where force is applied to it. Truss pattern refers to the arrangement of vertical and diagonal components within a structure. The upper and lower horizontal elements are commonly known as truss chords or booms.
Given: In this question, the figure that supports the question depicts a bridge on which there is a total of four stalled trucks that are evenly spaced out across the bridge. here, the payload capacity of the average truck is 64,000 pounds, while the weight of the cab is 8,000 pounds. Here, we take into consideration the fact that all truss members and call beam elements have the same cross section. I-beams are what hold the roadbed's weight of 1500 pounds up.
To do: using these cross sections for typical steel beam diameters, we need to...
