Abstract:

In a paper presented at the First International Symposium on Concrete Bridge Design, Toronto, April 1967 (1), a numerical method was used for the analysis of skew bridges composed of a deck slab monolithic with two main girders and the method was verified by model testing. In the present paper design tables prepared by this method are presented, giving the values of the bending and twisting moments and the reactions in the girders due to uniform load and the influence coefficients for these stress resultants in simply-supported skew bridges.

Abstract:

Right orthotropic bridges are analyzed by the Finite Strip Method. In this method harmonic functions which fitted the simply supported end conditions in one direction are used in conjunction with polynomials for the other direction, and as a result a simple beam-type stiffness matrix for a strip can be derived. Such an approach has been shown to be much more accurate and versatile than the Guyon and Massonnet methods of equivalent slabs.

Abstract:

Presents a method for the design of reinforced concrete girders for their shear strength. The method is based on a theory proposed by Iyengar and Rangan. Fifty rectangular beams were tested to check the working of the design method. These test results indicate that the proposed method of design is completely satisfactory except in the case of beams with single-legged skeleton stirrups.
