Abstract

A numerical procedure based on the finite element mate- rial nonlinear analysis of prestressed concrete beams with curved tendons is developed. This procedure includes all the stress phenomena of pre-- 1 stressed concrete beams with curved tendons such as f",.,.,...,,,.,,.,, ...

Numerical examples are presented to demonstrate the ity and applicability of the present procedure. The results are ,...,.,.,,,,.....,...,,,.,,...n with experimental results and the analytical results obtained by vestigators.
