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.

Torque-twist characteristics of reinforced concrete beams subjected to pure torsion, combined bending and torsion as well as combined bending, torsion and shear have been considered. . .A fair agreement between the computed and observed angles of twist was obtained.

The paper presents the analysis of statically indeterminate orthotropic bridge decks due to rectangular patch loads. Decks are classified into three main categories depending on relative rigidities in flexure and torsion.

The development of the theoretic interpretation of strength and deformation nature permits to outline two parameter points (stress levels), besides limit of strength. These objective criteria can be used while designing concrete and reinforced bridge constructions, as they influence many properties of concrete.

Skew bridge decks, and especially those made of prestressed concrete, are subject to longitudinal and transversal displacements and horizontal rotations due to external forcese resulting from: (a) Longitudinal braking and earthquake forces, (b) Transversal wind, earthquake and centrifugal forces, (c) Shortening of deck due to shrinkage, variation of temperature and prestressing forces.
