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.
Background technology
Reinforced concrete shear wall is widely used lateral resistant member in modern tall and super-high building structure, it is mainly used in bearing wind load or horizontal loading that geological process causes, control structure rigidity, makes structure meet Structural Design Requirement in global displacement with 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. Ductility and the bearing capacity of confined boundary member is increased, thus increasing the overall bearing capacity of reinforced concrete wall and deformability typically via increase edge member vertical applied force muscle and stirrup.
In ordinary reinforced concrete shear wall, obvious expendable plastic deformation is there will be after surrendering due to reinforcing steel bar bear, concrete material is relatively low due to tensile strength, compressive strength there will be material softening (stress decrease) after reaching, there is deformability difference in conventional concrete body of wall, the feature that ductility is relatively low, under strong horizontal load action (during as shaken greatly), reinforced concrete shear wall body of wall is likely to occur crack in tension, the phenomenons such as crushing of concrete, overall structure is made to exist because crucial lateral resistant member deforms the risk that the excessive irrecoverable destruction caused even is collapsed. although structural design can reach to avoid the purpose of the problems referred to above by the axial compression ratio or increase shear wall cross section size controlling shear wall, but it is excessive to may result in thickness of wall body, length, so not only increase construction costs, and it would furthermore be possible to impact building uses function, cause the problem that structural design and architectural design are difficult to coordinate. for solving the problems referred to above, the patent of invention that publication number is CN100434601C proposes to arrange concrete filled steel tube side column to increase the bearing capacity of shear wall, anti-seismic performance in the body of wall both sides of armored concrete. above-mentioned patent utilization steel tube confined concrete has good deformability and prolongs row, and the wall end position being placed on stress bigger can increase the deformability of body of wall and prolong row, but, the Self-resetting function (self-centering) that after surrendering due to steel pipe, concrete filled steel tube is overall is more weak, and after big shake, structure is still likely to occur the destruction of unrepairable. for this, 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, there is also the problem that steel using amount is bigger, other utilize the shear wall of concrete filled steel tube (such 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 big shake, but the problem of body of wall concrete in tension zone cracking and compressive region crushing of concrete when this patent unresolved large deformation. the utility model patent that China Patent Publication No. is CN201459963U proposes to adopt concrete filled steel tube built-in fabric reinforced composite pipe to be grouped combination shearing wall to increase the overall stress performance of structure and deformability in edge member part, makes 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 is relatively difficult with concrete filled steel tube bonding, being likely to reduce the integral working of faced wall, FRP pipe can not be guaranteed with the collaborative work of surrounding concrete simultaneously.
Above-mentioned discussion content purpose is in that to introduce, to reader, the various aspects being likely to the technology relevant to the various aspects of the invention being described below and/or advocate, believe that this discussion content contributes to as reader with background's information, to be conducive to being more fully understood that various aspects of the invention, therefore, should be appreciated that it is discuss to read these with this angle, rather than admit prior art.
