Document: 

SP23-07

Date: 

January 1, 1969

Author(s):

Ricardo P. Pama and Anthony R. Cusens

Publication:

Symposium Papers

Volume:

23

Abstract:

A method based on orthotropic plate theory is presented to determine the distribution of lateral loads in multibeam concrete bridges that have low transverse flexural rigidity or are torsionally stiff, and thus are outside the range of the Guyon-Massonnet approach.The deflection, bending and torsional moments, shearing and reactice forces are expressed as functions of dimensionless distribution coefficients.

SP23-29

Date: 

January 1, 1969

Author(s):

A. Murray Lount

Publication:

Symposium Papers

Volume:

23

Abstract:

In this article the author discusses the application of continuity to prestressed concrete, making reference to a number of structures so designed. A method of analysis is demonstrated that may be used to simplify the design and cable layout in such structures.

Author(s):

Hans Wittfoht

Publication:

Symposium Papers

Volume:

23

Abstract:

The procedure of spanwise construction in cast-in-situ concrete, using some movable form work technique, has proved most suitable for larger-size prestressed concrete bridges.
