Abstract: |
The present work delivers one experimental study of a new type of joint reinforcement for box- girder bridges constructed evolutionarily, seeking to reduce execution time, improve formwork placement inside the box section, and minimize work risks. For this reason, failure tests are carried out in reinforced concrete slabs, comparing the experimental results of proposed joint with continuous reinforcement and a loop union according to DIN 1045. The results are delivered in terms of resistance, deflection and concrete joint opening for a pure bending test. They are also included the results of a fatigue test, waiting to conclude in the next future the work about the behaviour of different concrete slabs. |
