AI Technical Summary

Problems solved by technology

At present, domestic and foreign studies on the reinforcement performance of reinforced concrete columns are mostly focused on the stress-strain relationship, bending moment-curvature relationship, improvement of shear and bending resistance, seismic performance and ductility performance of a certain material after reinforcement. etc., but there are few studies on the situation of multi-material composite reinforcement

Embodiment Construction

[0010] Referring to the attached figure, the fiber-reinforced plastic (FRP) is pasted around the compression member with a fiber adhesive to restrain the lateral deformation of the concrete, and the four corners of the concrete member covered with fiber-reinforced plastic (FRP) are glued with building structures Attach profile steel 2, profile steel 2 directly bears a part of the load, so as to directly pass the bearing capacity of the compression member, and at the same time weld the steel panel 3 and profile steel 2 to form a steel skeleton system, and then integrate it with the concrete through bolts 4, that is Realize the reinforcement of concrete compression members.

Abstract

A method for reinforcing the pressure-bearing concrete member features that the fibre-reinforced plastics (FRP) is used to wrap the said concrete member and the shaped steel pressing on the FRP is fixed to it via fasteners. Its advantages include greatly improved mechanical performance, high load-bearing power and deformation resistance.

Description

technical field [0001] The invention relates to a method for strengthening concrete compression members. Background technique [0002] China has a huge construction market. In industrial and civil buildings, due to design and construction defects and factors such as damage, aging and disasters in the long-term use of many concrete structures, a considerable part of the components are cracked, the seismic performance is poor, and the bearing capacity Insufficiency and many other problems that affect safety and usability need to be reinforced. In addition, due to the requirements of adding floors to the building structure, the bearing capacity of the original structure is insufficient, and some method is needed to greatly increase the bearing capacity of the components. [0003] The usual reinforcement method for concrete compression members is to use newly poured concrete to increase the column cross-section or adopt outsourcing steel reinforcement method. The method of enl...
