Adjacent Box Beam Connections: Performance and Optimization

CHAPTER 6. SUMMARY AND CONCLUSIONS

Full-scale testing on adjacent box beam connection methods was conducted as part of this study. Four shear key connection designs were evaluated. The first two designs utilized both partial- and full-depth conventional grouted connections with various levels of transverse PT. The other two designs utilized partial- and full-depth UHPC connections with non-contact lap-spliced reinforcement. Transverse PT was not used in the UHPC connections. The beams were subjected to 10 cycles of thermal loading and millions of cycles of structural loading.

SUMMARY

The main findings are summarized as follows:

CONCLUSIONS AND RECOMMENDATIONS

Conclusions and recommendations related to adjacent box beam connection design and performance evaluation include the following:
