Description

Pennsylvania State University Department of Civil and Environmental Engineering C E 340: Structural Analysis Spring 2019 Problem Set # 2 Due: Thursday, January 31 1. Classify each of the structures as statically determinate, statically indeterminate, stable, or unstable. If indeterminate, specify the degree of indeterminacy. (20 pts.)

2. Determine the reactions at the supports of each given structure. a) The beam is supported by a roller at A and B, and by a pin at C. There is a pin connection at D. (25 pts.)

b) The beam is supported by a roller at A and a pin at B. (25 pts.)

c) In addition to support reactions calculate the internal forces at B as well. Members are pin connected at A, B and D, and there is a fixed-connected joint at C. (30 pts.)
