Abstract
Practical ultimate design methods in finding bending moment envelopes are explained and examples are given. An attempt has been made to find the relation between the ratio of total load to dead load with respect to cracking lengths, hyper-plastic moments,support moments and efficencies of design. Graphs are plotted and tables are presented to verify such relations.A new method is developed by using the relation of cracking length to span, hyper-plastic moment, support moment against the total load to dead load ratio. It is found that standard curves can be plotted from which bending moment values could be found easily for frameworks. These charts can be used for the reinforced concrete members in which redistribution up to 30% of moments can take place. This method of analysis is found satisfactory when compared with other methods in the analysis of five equal span continuous beam.
