The buckling-restrained shaped steel plate shear wall structure of soap-free emulsion polymeization part of the present invention, supporting capacity is strong, is not easily out of shape.
Description
Technical field
The present invention relates to a kind of shear wall structure, it is specifically related to a kind of buckling-restrained shaped steel plate shear wall structure of soap-free emulsion polymeization part.
Background technology
The rigidity of skeleton construction is relatively little, when the height of structure increases, when anti-side rigidity does not meet design requirement, can arrange lateral resistant member in the frame, it is to increase the anti-side rigidity of structure, and the side effectively reducing buildings is moved. Steel plate shear force wall structure is a kind of novel lateral resisting structure that eighties of last century grows up the seventies. Under lateral forces, after surrendering (thin plate) or surrender after filling out the bucking of plate in steel plate shear force wall, flexing (slab) can also continue bearing load, even when interior fill out plate tear, its performance degradation is also not obvious, have that initial side direction rigidity is big, hysteresis stable performance, energy dissipation capability is good, ductility is big, resist cyclic load under the advantages such as distortion ability is strong.
By the research of thin steel plate shear wall is found, there is following problem in thin plate wall: with the similar sound beaten a drum during (1) flexing, and is out of shape outside producing bigger face, and this means in bigger wind loading or earthquake action process, comfort level is undesirable, it may also be useful to property is not good enough; (2) after steel sheet flexing, formation draws position effect side column can be produced bigger additional bending moment, adds the stable burden of post; (3) hysteresis loop has Draw shrinkage in various degree, limits applying in its actual engineering.
Steel sheet wall is arranged suitable putting more energy into or adopt concrete faced wall, thin plate is divided into community lattice or out-of-plane buckling constraint that stress performance is similar to slab, not only can reduce the flexing noise of wallboard, moreover it is possible to improve the hysteretic energy of wallboard significantly. But put more energy into and it is connected with wallboard fillet weld, internally fill out plate welding and not only bring bigger unrelieved stress and residual set, reduce the lateral resistance of structure, and bond completely due to ribbed stiffener and interior embedding wallboard, participate in having resisted a part of horizontal force while constraint wallboard, stiffener buckling easily occurs, prior to the situation that entirety is destroyed, can not continue to play the function suppressing flexing. Adopting concrete faced wall, concrete slab cracking phenomena also occur, deactivate in advance, increase dead load simultaneously, increase seismic structural response, increase basis expense, research also finds that the setting of concrete faced wall or anti-buckling component reduces the ductility of component.
