A new anchorage method of the CFRP grid in the mortar named intersect-type anchorage method was proposed in this paper. Single-direction pull-out tests and bidirectional pull-out tests were conducted to investigate the anchorage behaviour of the CFRP grid in the mortar. The number of nodes and anchorage conditions were selected as changing parameters. Based on the experimental results, the number of nodes for full use of the tensile strength of the CFRP grid was analysed. Besides, the failure mechanism was discussed.
