Description
Technical field:
The present invention relates to a kind of novel shear wall, relate in particular to a kind of multiple-chamber type double steel plate combined concrete shear wall, belong to civil engineering structure technical field.
Background technology
In recent years, along with the fast development of China's economy, urbanization was accelerated greatly.A large amount of population is poured into city, and expanding economy, and land resources day is becoming tight.For relaxing people ground contradiction, house and commercial building etc. all presents the development trend of high stratification, superelevation, and this also has higher requirement to corresponding form of structure, and the one, it has good mechanical property requirement, as lateral deformation stiffness, ultimate bearing capacity etc.; The 2nd, it has good ductility and energy dissipation capacity requirement, so that whole building is under stronger seismic loading, can there is moderate finite deformation, more energy dissipates, thereby guarantee that structure does not collapse and significantly destroy, with effective guarantee people's life security and property safety; The 3rd, it has good application property, simple structure requirement.
In highrise building, conventional lateral resistant member has two kinds of framework and shear walls, and wherein the mechanical property of shear wall is better than framework, builds higher, shear wall application is more, and the shear wall of traditional form is in mechanical property, anti-seismic performance with more or less there is certain deficiency above construction simplification.
1) reinforced concrete shear wall and Profiled bar concrete combination shearing wall
Although reinforced concrete shear wall and Profiled bar concrete combination shearing wall rigidity large bearing capacity are high, all there is serious deficiency in ductility and energy dissipation capacity.
2) steel plate shear force wall
Steel plate shear force wall mechanical property or Hysteresis Behavior are all more satisfactory in theory, but due to the outer flexing of its easy generating plane, make its complex structure and utilize insufficient.
3) single steel plate concrete combined shear wall
Single steel plate concrete combined shear wall is hanging concrete plate on steel plate shear force wall, to prevent the outer flexing of face of steel plate.Correlation test shows, the purer steel plate shear force wall of the Hysteresis Behavior of the shear wall of this kind of form and mechanical property improves, but due to the large reason of concrete slab rigidity, concrete slab is easy to ftracture, make it can not effectively prevent steel plate flexing, also largely affect its comfortableness and applicability simultaneously, in addition, its also more complicated of constructing.
A kind of novel compound shear wall, i.e. double steel plate combined concrete shear wall have been risen the nineties in 20th century.This kind of compound wall is comprised of steel plate and the inner cast-in-place plain concrete body of wall of both sides, between steel plate and concrete, by a large amount of shearing resistance pegs, stiffening rib, vertical next door etc., be connected, to guarantee the collaborative work between the two, two block plates in plain concrete outside are by drawing the connections such as batten plate of welding on reinforcing bar, vertical baffle, stiffening rib, with the shearing outside resistance wall dignity and constraint concrete deformation, as Fig. 1.The experimental study of double steel plate combined concrete shear wall shows, its initial stiffness is large, and bearing capacity is high, and ductility is better, and hysteresis loop is full, and energy dissipation capacity is strong, without the flexing sound.In construction, wall outer side double steel plate is equivalent to template, and additionally formwork, and double steel plate outside framework can be processed in factory's modularization again, then welding at the scene, greatly reduces the difficulty of its site operation, has greatly accelerated speed of application.Aspect fire resistance, the fire resistance test of double steel plate combined concrete shear wall shows, the purer steel plate shear force wall of fireproof performance of this body of wall is good, because when being heated, the steel plate of wall outer side mainly plays heat is conducted to inner concrete effect, and heat can not accumulated on the steel plate of outside, even so, outside steel plate is still in direct exposed thermal field, and steel billet temperature is still higher, and its fire line still needs specially treated.In addition, double steel plate combined concrete shear wall is the same with other steel work, need to do special preservative treatment, to improve the durability of structure.
