摘要:
设计一套圆弧槽夹板式锚具,通过拉拔试验研究锚具的夹持性能,并研究包括施加于夹板紧固件螺栓上的总扭矩值和扭矩沿夹具纵向分布等主要参数对锚具性能的影响.结果表明,总扭矩值和扭矩分布均对锚具的性能有明显影响.当施加在夹板紧固件螺栓的总扭矩值小于200 N.m,试件最终将发生滑移破坏; 当总扭矩值超过200 N.m,试件最终发生碳纤维增强复合材料(CFRP)筋断裂破坏,且极限荷载随总扭矩值的增加而降低.扭矩沿加载端向自由端递增分布,将使锚具获得更好的性能.
Abstract:
A new type of clamping anchor with arc groove for carbon fiber reinforced polymer(CFRP) rods is proposed.The performance of the prestressed anchor is investigated by pullout tests.The main parameters include the value and distribution of torque applied to the bolt fasteners.It shows that the value and distribution of torque influence greatly on the performance of clamping anchor.When the value of torque is less than 200 N·m,the anchor system fails due to slippage.When the torque is greater than 200 N·m,the anchor system fails due to CFRP rod rupture,and the failure load decreased with increasing the value of torque.When the value of torque increases from loading end to free end,the anchor shows better performance.A proper torque distribution for this anchor system is put forward.
