Optimization Study on FRP Bolt-End Structure Parameters
A new FRP bolt-end structure is presented and its structure characteristic is introduced in detail. The FRP bolt-end structure is optimized to determine the optimization structure by multi-target orthogonal experiment. The experiment results for the FRP bolt with the optimal structure shows that anti-drawing strength is more than 85kN, elongation percentage is more than 2.5% and bolt-end joint strength is more than 64kN. Its features can satisfy coal side support demand. So the new structure designed is reasonable.
