If you know the area of the cross section (that you mentioned) then multiplying the area by the density, you will get the weight per foot of the member. The single traffic lane is 12 feet wide and is equidistant from the side of the tunnel. The centroidal distance in the y-direction for a rectangular cross section is shown in the figure below: Common uses for centroidal distance include: calculating the maximum bending stress in a cross section. Once, you do that, finding the cross-sectional area or simply the area of the circle at the distance X from the base. A skew arch (also known as an oblique arch) is a method of construction that enables an arch bridge to span an obstacle at some angle other than a right angle.
