(1) The flexural strength of RC beams strengthened with CFRP laminate can be increased by 20%-90% and the ultimate strength can be increased by 20%-90%. The bending resistance is not directly proportional to the number of paste. At the same time, increasing the width of CFRP has a certain effect on cracking load. Good anchorage measures have significant effect on bending capacity.

(2) The stiffness of concrete beams is improved and the deflection curve is decreased after the surface is strengthened with CFRP laminate. The reinforcement of CFRP laminate has a certain effect on the stiffness of beams. The reinforced beams without anchorage usually have early failure due to the exfoliation of CFRP laminate and concrete, and the reinforcement effect is not very good. Different anchorage measures have different reinforcement effects. This indicates that good anchorage measures have a significant effect on the stiffness of reinforced beams.

(3) The existence of CFRP laminate makes the steel bar strain lag behind the unreinforced beam, which is not obvious at the initial stage of loading, but this phenomenon will become more significant when the load is large. The strain of the CFRP laminate of the reinforced beam without anchorage measure is small, which is mainly due to the spalling of CFRP laminate. In the case of better anchorage measures, the stress of CFRP laminate is relatively large, and the tensile properties of CFRP laminate are fully exerted, playing a very good role in strengthening.

(4) For the strengthened beams with anchorage measures, the crack development speed and width are obviously slower than those without or without anchorage measures. This shows that there are better anchorage measures, and the crack development and crack width control has a better inhibition.
