Mechanical Behavior of Prestressed Structure Made with Chipped FFU

Supervised by Kyuichi MARUYAMA

The process of making Fiber Reinforced Foamed Urethane (FFU) products produces some amount of FFU waste. It is required to reuse such waste material by environmental factors. In this study, I examined mechanical behavior of prestressed structure for ground anchoring method made with chipped FFU waste. In particular, I decided that the height of prestressed structure and amount of reinforcement by FRP sheet to be the main factor of examination.
The static loading test results showed the following:
(1) Contact pressure of prestressed structure is uniformly distributed.
(2) It is more effective to make a highly product in order to improve failure load rather than increasing the amount of FRP sheet reinforcement.
(3) If it is made suitable height of prestressed structure and the amount of FRP sheet reinforcement, the use of the prestressed structure is possible.
