A precast T beam is to be used as a bridge over a small roadway. Concrete dimensions are b = 1500 mm, bw = 300 mm, hf = 150 mm, and h= 650 mm. The effective depth d= 500 mm. Concrete and steel strengths are f 'c= 40 MPa and fy = 420 MPa, respectively. Determine the design moment capacity of the girder. If the beam is used on a 10 m simple span, and if in addition to its own weight it must support railings, curbs, and suspended loads totaling 4 kN/m, what uniform service live load limit should be posted?

What will you propose for a concrete mix design to be used in constructing a bridge pier during a cold winter month. The bridge is designed to be constructed on a site where sulfate attack on the concrete is a problem. In this project, high cost is not allowed and the concrete’s cost must be priority without lowering quality.

Based on research, list (3) specific considerations for use of steel, reinforced concrete (precast or site-cast), OR wood structural elements in design. In other words, list specific situations in which a particular material would be a good or bad choice. Don’t simply list a characteristic of the material. Be careful to describe in what specific situation, building type, or project type that particular characteristic would be beneficial or detrimental. For example: When using precast concrete, you must have adequate laydown...
