Abstract

The ultimate load of prestressed high-strength concrete T-beam was analyzed with material nonlinear properties being taken full consider of. Both solid and one-dimensional elements were used for reinforcement concrete and prestressed bar. Curve p-f was given for whole loading procedure. Based on the above theory, influence of main parameters upon the ultimate load was analyzed.The scope of these parameters was acquired, which could provide reference to design and calculation.

Key words

bridge engineering / high-strength concrete beam / finite element method / ultimate load / nonlinear / parameter analysis
