Analysis and brief design of two span reinforced concrete gable frame
Abstract
Scope of Study: The analysis and brief design of a two span reinforced concrete gable frame by the elastic and the concept of limit design approaches are presented in this report. The procedure of analysis for each of these methods is outlined and the design procedures for typical sections are presented. The elastic analysis is accomplished by using "Moment Coefficient Tables," and the "Plastic Hinge Theory for Reinforced Concrete Frames" is applied in the limit design approach. Finally, cross-sectional dimensions and the corresponding steel requirements for several critical sections are shown and compared. Findings and Conclusions: It is shown that for a two span frame the plastic method of approach offers a simpler solution and eliminates the solution of simultaneous equations, which is a necessary step in the conventional elastic method of analysis, and would become a cumbersome and quite tedious task as the number of redundants of an indeterminate structure increases. The writer feels inclined to recommend the careful adoption of the limit design approach for the analysis of indeterminate reinforced concrete structures with a higher degree of indeterminacy.
