玻璃纤维增强聚合物锚杆锚头试验研究
Experimental study on anchor head of GFRP bolt
摘要
Abstract
A series of model tests were conducted on the ultimate tensile capacity of glass fiber reinforced polymer anchors using the mental screw nut and the glass fiber anchor head.The results show that when the mental screw nut is longer than 10cm,the ultimate capacity of GFRP anchor head will be achieved.The failure model of the GFRP anchor is the damage of the surface,and the average failure thickness of the failure surface is about 2.4～2.7mm.The most resistance to shear failure comes from the matrix resin and small parts of nearby glass fiber.The ultimate tensile capacity of GFRP anchors with an 8cm length of glass fiber head is approximately equal to that of the metal nuts with a length of 6 to 7 cm.However,the displacement is about 2 times the latter.关键词
