Abstract EN
In this study, a three dimensional finite element analysis was utilized to study the behavior of reinforced concrete T-girders with and without web openings under pure torsion by using ANSYS APDL 15.0 program.
Fourteen reinforce concrete T- girders were analyzed; one of the girders (without web openings) was modeled as a control girder.
The analysis variables considered for the other girders are: size, shape, position of web openings, number of web openings and the method was used to strengthen the member at openings, (using internal deformed steel bars as in the case where the openings are planned before casting the girders).
To study the general behavior of finite element models, torque-angle of twist plots at the end of the span near the loaded arms were represented.
From this relation, it was showed a decreasing in the strength of the T-girders with web openings under the torsional loads and increasing of the angle of twist.
The results were analyzed in terms of torque twist characteristics; ultimate torque, crack patterns, crack width, warping and stresses.
These terms were presented and a comparison between the finite element results was made.
