Test On Designing Method Of Wave-shaped-gear-grip Anchor

CFRP strengthen possess construction,which abroad in recent years with the advantage of cycle short, not increase dead load. However, bonding failure premature will occure between CFRP and member if plastered straightly.At the same time,the CFRP's intensity will not exert sufficiently,deflection of member will not be decreased. Hence, the techniques of gripping and anchoring FRP composite have became the key technique and must be resolved。Innovative by our team ,WSGG(wave-shaped-gear-grip) anchor is based on the FRP sheets or laminations. Experiment based on WSGG anchor has gotten more progress. However, the test on design method of WSGG anchor does not initiate,such as how to quantify three anchorage effect,the prestress of CFRP stretching by WSGG. So we will develop a research about two assignment. Seting introduction mechanics model for WSGG anchor and achieve the prestress of CFRP.According to the data from the experiment, we find the and mechanism of WSGG anchor and present the designing formula of WSGG anchorage length.
