Description
Technical field：
The present invention relates to a kind of existing reinforced concrete structure reinforcing construction and its reinforcement means based on BRB.
Background technology：
In the violent earthquake that recent domestic occurs, the BEFORE SOME STRONG EARTHQUAKES that especially China has undergone since 2008, there is big dimension
Tendon concrete frame structure (Reinforced concrete, RC) collapses, and mainly building of tracing it to its cause lacks foot
Enough ductility and energy dissipation capacity.After 5 12 Wenchuan earthquakes, China is based on earthquake experience to original《Seismic design provision in building code》
(GB50011- 2001) is revised.Newly issue and implement《Seismic design provision in building code》(GB50011-2010 improves portion
The seismic fortification intensity of region-by-region, have adjusted classification of design earthquake, improve the Aseismic Design to concrete frame structure house
It is required that, add building aseismicity Performance Design principle.By during old Specification Design to the elastic-plastic deformation of structure under rarely occurred earthquake
Checking computations are normally only carried out for a small number of important features, and substantial amounts of general structure then relies primarily on conceptual Design of Earthquake Resistance and construction
Measure ensures the target of setting up defences of " no collapsing with strong earthquake ".Above-mentioned factor causes a large amount of existing reinforced concrete frame structures of active service to exist
Future, which meets with, has the risk collapsed under rarely occurred earthquake effect, and does not allow all to push over weight for economy and social cause
Build, therefore it is inevitable choice to carry out seismic hardening to it, the painful experience and lessons of all previous earthquake have also been declared publicly antidetonation before shake and added
Solid importance and urgency.
At present, the seismic strengthening technology of existing building mainly has：Increasing section method for strengthening, steel-encasing strengthening method, stickup
Fibrous composite（FRP）Method for strengthening, set up the methods such as shear-wall strengthening method, base isolation method for strengthening.These reinforcement means or
Taken a lot of work due to time-consuming, or due to the use and the influence of architectural appearance to space, or because cost is high, or because of excessive increasing
Plus dead load and the power performance for changing existing building, or because that the reason such as can not change after shake, all in the presence of certain limitation
Property.
