Method for reinforcing structures through method of externally pasting reinforced concrete frame with ductility column energy dissipators

Abstract

The invention discloses a method for reinforcing structures through a method of externally pasting a reinforced concrete frame with ductility column energy dissipators, and belongs to the field of reinforcement of concrete structures. The reinforced concrete frame with the ductility column energy dissipators is externally pasted on the outer side of an original reinforced concrete frame structure. The intensity grade of the concrete and the intensity grade of the reinforcing steel bars of a newly added frame beam and those of a newly added frame column are higher than those of an original frame beam and those of an original frame column, and the intensity grade difference should not exceed two. The newly added frame beam and the newly added frame column are connected with the original frame beam and the original frame column respectively through an adhesively bonded anchorage mode. The adhesively bonded anchorage mode is achieved through the fact that embedded steel bar glue is implanted by drilling anchor bars to be fixedly connected with original frame concrete. The anchor bars and the newly added frame structure are cast in situ. Each reinforced concrete ductility column energy dissipator comprises a reinforced concrete ductility column and rigid supports at the two ends of the corresponding reinforced concrete ductility column. The intensity grade of the concrete and the intensity grade of the reinforcing steel bars of the reinforced concrete ductility column energy dissipators are identical to those of the newly added frame. The reinforced concrete ductility column energy dissipators and the newly added reinforced concrete beam are integrally cast in situ. The method is quite beneficial to reinforcement effects.

Description

technical field [0001] The invention belongs to the field of concrete structure reinforcement, and in particular relates to a reinforced concrete frame method reinforcement structure with ductile column energy dissipators. Background technique [0002] Reinforced concrete frame structures and bottom frame structures have been widely used in multi-story buildings due to their flexibility in spatial arrangement. Due to the different functions of the bottom frame structure, the structural layout is different, and it is easy to form a structural system with uneven rigidity and rigid top and soft bottom. There may be a serious lack of earthquake resistance, and tilting or collapse will occur during an earthquake, which will cause great obstacles and economic costs to structural repair and disaster relief. [0003] my country's "Code for Design of Reinforcement of Concrete Structures" (GB50367-2006) proposes a variety of reinforcement methods. For example, the method of enlargin...

Problems solved by technology

The combination of the existing structure and the external high-ductility reinforced concrete energy-dissipating column frame not only increases the energy-dissipating and shock-absorbing effect of the structure, but also solves the problems that the old and new concrete lack connections and cannot form a whole, and the stress-strain lag problem
