Abstract
The invention discloses a composite shear wall with FRP (fiber reinforced polymer) tubes and metal tubes arranged inside. The composite shear wall is characterized in that the FRP tubes are arranged inside the shear wall; the metal tubes are arranged in the FRP tubes; concrete is contained between the FRP tubes and the metal tubes. The FRP tubes and the metal tubes are utilized to restrain the concrete between the FRP tubes and the metal tubes to improve the strength and deformability of the concrete. Meanwhile, the metal tubes are restrained by the concrete and the FRP tubes, and the outward buckling modes of the metal tubes are inhibited, so that the buckling resistance of the metal tubes is obviously improved. The FRP tubes and the metal tubes are put in the positions, which deform more seriously or are compressed more seriously, of walls, such as one or more of positions including wall ends, the intersection of two wall columns and the intersections of a plurality of wall columns, so that the composite shear wall not only has the characteristics that the composite shear wall has strong deformability and the concrete in the compressive zone is not easy to crush, but also has obvious second-order rigidity; therefore the walls have the self-centering function during large deformation.
Description
Technical field
The invention belongs to reinforced concrete structure technical field, be specifically related to the compound shear wall of a kind of built-in fabric reinforced composite pipe and metal tube.
Background technology
Reinforced concrete shear wall is widely used lateral resistant member in modern tall and super-high building structure, be mainly used in bearing the horizontal loading that wind load or geological process cause, control structure rigidity, makes structure meet Structural Design Requirement in global displacement and relative storey displacement.Reinforced concrete shear wall is generally made up of wall body and edge member.According to different seismic behavior needs, edge member can be designed to structure edge member or confined boundary member.Generally increased ductility and the bearing capacity of confined boundary member by increase edge member vertical applied force muscle and stirrup, thus increase bearing capacity and the deformability of reinforced concrete wall entirety.
In ordinary reinforced concrete shear wall, owing to there will be obvious expendable plastic strain after reinforcing steel bar bear surrender, concrete material due to tensile strength lower, material softening (stress decrease) is there will be after compressive strength reaches, there is deformability difference in conventional concrete body of wall, the feature that ductility is lower, under strong horizontal load action (during as shaken greatly), may crack in tension be there is in reinforced concrete shear wall body of wall, the phenomenons such as crushing of concrete, overall structure is existed because crucial lateral resistant member is out of shape the risk that the excessive irrecoverable destruction caused even is collapsed.Although ratio of axial compressive force to axial compressive ultimate capacity of section or increase shear wall cross section size by controlling shear wall in structure design reach the object avoiding the problems referred to above, but thickness of wall body, length may be caused excessive, so not only increase construction costs, and building using function may be affected, cause structure design and architectural design to be difficult to the problem coordinated.For solving the problem, publication number is that the patent of invention of CN100434601C proposes to arrange concrete filled steel tube side column to increase bearing capacity, the anti-seismic performance of shear wall in the body of wall both sides of steel concrete.Above-mentioned patent utilization steel tube confined concrete has good deformability and prolongs row, and being placed on stressed larger wall end position can increase the deformability of body of wall and prolong row; But because after steel pipe surrender, the Self-resetting function (self-centering) of concrete filled steel tube entirety is more weak, after large shake still may there is the destruction of unrepairable in structure.For this reason, China Patent Publication No. is that CN102127941B and CN104088378B patent of invention proposes to utilize on the basis of concrete filled steel tube at wall end, at wall body, steel plate is set to increase the ductility and deformation behavior of wall body part further, this two patent is except the shortcoming that there is China Patent Publication No. CN100434601C, also there is the problem that steel using amount is larger, other utilize the shear wall of concrete filled steel tube (as China Patent Publication No. CN202380606U, CN104818784A, CN202380574U, CN203808295U etc.) also all there is similar shortcoming (namely without Self-resetting function).China Patent Publication No. is that the utility model patent of CN201459963U proposes to configure high tensile reinforcement in whole or in part at edge member and wall body, fiber-reinforced composite material rib makes body of wall have Self-resetting function when large shake; But this patent and unresolved large deformation time body of wall concrete in tension zone cracking and the problem of pressure zone crushing of concrete.China Patent Publication No. be CN201459963U utility model patent propose edge member part adopt concrete filled steel tube and built-in fabric reinforced composite pipe composition compound shear wall to increase stress performance and the deformability of structural entity, make structure have certain second order rigidity and Self-resetting function simultaneously; But the application of combinations thereof shear wall has certain difficulty, the horizontal reinforcement being mainly manifested in wall body part bonds more difficult with concrete filled steel tube, may reduce the integral working of compound wall, FRP pipe can not be guaranteed with the collaborative work of surrounding concrete simultaneously.
Above-mentioned discussion content object be to reader introduce may to below by the various aspects of technology relevant for the various aspects of the present invention be described and/or advocate, believe that this discussion content contributes to for reader with background's information, to be conducive to understanding various aspects of the present invention better, therefore, should be appreciated that it is discuss to read these with this angle, instead of admit prior art.
