Saiidi Receives US Patent for Deconstructible Column Plastic Hinges

US Patent No.: US 9,677,274 B2

 

Dear Visitor:

Welcome to our website! Highlights of a research project on two novel concepts toward earthquake resistant concrete bridges are presented on this website.  The novel concepts are the application of advanced materials and details and devising bridge columns that can be disassembled and reused.   The former is intended to provide strength and resilience under extreme loads and the latter is intended to reduce bridge construction impact on the environment and energy use.  The project is funded under the National Science Foundation program Partnership for Innovation.  It is collaborative with four innovative small businesses that are active in different aspects of advanced materials development and application. 

Please feel free to use the material posted on this site with acknowledgement that includes statements such as “…funded by the National Science Foundation Grant IIP-1114406 and directed by M. Saiidi at the University of Nevada, Reno.” We welcome your comments about this site.

Acknowledgments:
Our special gratitude goes to Dr. Sara Nerlove and Dr. Alexandra Medina-Borja, the NSF Program Directors, for their support and guidance in the course of this project. Also, thanks to Dr. Salem Faza of the MMFX Steel Corporation of America for donating the high strength steel bars and Greg White from Disc-Lock, Inc. for donating locking nuts. Prof. Yoshikazu Araki of Osaka University and Mr. Sumio Kise of Furukawa Techno Material Co., Ltd. of Japan  are thanked for their close collaboration in developing and supplying the Copper-Aluminum-Manganese (CAM) bars for this project. The research team is also indebted to Messrs. Christian Dahl and Joseph Morente of Headed Reinforcement Corp. (HRC) for donating materials, the AVAR-SAS Company for donating time and material in post-tensioning the bridge model, and to Messrs. Aaron Holmes and Troy Olson at the Nevada Department of Transportation Materials Lab for their help with material testing.

The material in this site is based upon work supported by the National Science Foundation under Grant No. IIP-1114406. The UNR shake table site operation and maintenance is funded by Grant No. CMS-0402490.
