Problem 1 The McConnell Drive bridge is a three-span continuous steel girder bridge. A photograph, looking west at the east elevation, is shown. Determine all internal member forces - axial(N), shear(V), and moment(M) - Draw a free-body diagram (you choose what side of cut) Write equations of equilibrium Solve for unknowns 14 4m 47-0" 75'-0" 47-0" Sk 8k 8k 24' 1k/ft.

The sum of all forces on object, part, and particle is zero. ZF =0 b. The internal shear in a bending member is the integral of the external loading and the internal moment is the integral of the shear. V = Jw-dx and M = SV-dx c. The force applied to an object is the product of its mass and acceleration. F= m-a d. The load effect caused by two or more loadings is equal to the sum of the load effects caused by each individual loading F(x1+x2) = F(x1) + F(x2) In 2-3…
