Abstract:
Reports on an investigation of the response of simply supported singly and doubly reinforced beams to arbitrary. repeated loading. A numerical method using load deflection relationship for computing strain factors at various stages of loading is proposed. Moment factor equations are devel-oped involving the parameters like modular ratio, per-centage reinforcement, ratio of compression steel area to tension steel area, strain factor, and stress ratio. The theo-retical and experimental comparison indicates that the theoretical equations involving strain factors may give a rough indication of the behavior of reinforced concrete beams under repeated loading.
