Extracted text: For the simple span bridge superstructure shown below, determine: the superimposed dead load DC for the parapets and DW for the wearing surface applied to each prestress concrete box beam. the maximum moment due to superimposed dead load DC for the parapets and DW for the wearing surface applied to each prestress concrete box beam. Assume that the deck consists of a 225 mm think structural Portland cement concrete including a 13 mm-thick bituminous wearing surface. Use the following data for material weight: Wbox beam = 11.4 kN/m Yconc = 22.8 kN/m³ Yasphalt = 22.0 kN/m³ The parapet weight may be evenly distributed among the five beams. Note also that you are not required to include live load.
