“…However, minimum weight of reinforcement results in the angle of inclination which is half of that required for minimum force Fa. 15. LeonhardP (page 189) has stated that nature is not aware of any truss analogy and acts according to the law of minimum deformation work.…”

7964Design of deep beams with partially predefined reinforcement geometry This Paper describes a general method of analysis and design based on the concept of partially predefined reinforcement geometry. This method is applicable to all structures to which the simple bending theory does not apply and for which a truss action can be justified to be the mechanism of load transmission. The method is applied to directly and indirectly loaded deep beams. The indirectly loaded beams can also be indirectly supported. The design rules derived are similar to the currently available empirical design rules. This similarity provides a verification of the proposed method and gives an analytical foundation to the current design rules, thus adding to their rationality and applicability. The method proposed is completely analytical; some of the expressions and design rules, which are not known currently, await experimental verification. Due consideration is given to the practical aspects of design and a design example is given.complementary potential, which reduces to the principle of least work for linear elastic-perfectly plastic material and non-yielding supports. 3.To ensure that the collapse load of beams is not far from the actual collapse load, the choice of reinforcement geometry and the resulting mechanism of load transfer (truss model) should depend on some measure of the behaviour Written discussion closes IS November, 1977, for publication in Proceedings, Part 2.
