Abstract:
Discusses the factors affecting the deflection of reinforced concrete members and emphasizes the importance of taking them all into consideration for an accurate estimate of deflection. Includes a table with an extensive list of situations requiring deflection limitations. These are based on L/ A ratios and absolute values applied to the total or incremental deflections. Discusses the most significant parameters af-fecting the L/D ratios as an indirect limit on deflections. Presents formulas and graphs for L/D and gives examples for their use. The report is divided into five chapters: Introduction, Computation of Deflections, Allowable Deflections, Allowable Span/Depth Ratios, and Correlation with Actual Building Structures.
