Influence LinesforaStatically Determinate Continuous Beam problem statement Draw the qualitati veinfluence lines for the vertical reactions at the supports, the shear and moments at sections sI and s2, and the shear at the left and right of support B of the continuous beam shown.

The resulting deflected shape will be proportional to the influence line for the support reactions. The resulting influence lines for the support reactions at A, B, and C are shown in Figure 2, below.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
