Abstract:
Elastic design of prestressed concrete beams involves comprehensive analysis of stresses in concrete section under extreme opposite loading conditions, usually transfer of prestress and fully loaded service stages. . .The modified technique is described, formulas developed and specimen charts appended. The simplicity of design chart preparation, and the versatility of application of the graphical mehthod to prestressing tendon design are demostrated with examples.
