Description

Steel and combined concrete shear wall and its construction method

Technical field

The present invention relates to building structure field, more particularly to a kind of steel and combined concrete shear wall and its construction method.

Background technology

Shear wall is important lateral resistant member in modern high-rise building.With constantly soaring, the shear wall of building height The load for being undertaken also increases therewith, is particularly at the shear wall of highrise building fundus, except need to have great bearing capacity Outside, should also have good ductile performance.And traditional reinforced concrete shear wall is no matter in mechanical property, or building Functionally all it is difficult to meet higher requirement.Steel obtains larger with the conditions of less section with combined concrete shear wall Bearing capacity and component ductility, be widely used in skyscraper.

At present, steel-concrete compound shear wall mainly include three major types, be respectively steel reinforced concrete shear walls, steel pipe mix Solidifying local soil type's combination shearing wall, steel plate concrete combined shear wall, but these shear walls are no matter in terms of mechanical property, or in construction Also there is certain deficiency in aspect.For steel reinforced concrete shear walls,《Reinforced concrete composite structure technical regulation》 (JGJ138-2001) way for specifying is that shaped steel (mostly I-beam) is arranged in confined boundary member, shaped steel mixing end Solidifying soil is divided into many parts, and the outer concrete for being particularly its flange area is very thin, and this causes the coagulation in confined boundary member region Soil be difficult perform to its due bearing capacity, furthermore as the section thickness of shear wall is limited, be also not easy to arrange shaped steel with Connector between concrete;Steel plate concrete combined shear wall either adopts single steel plate or double steel plate is both needed to set in plate face Put the construction measure being connected with concrete, common pin connection is clouded on whole face steel plate, greatly increased welding and Difficulty of construction, and steel plate outer surface need to carry out corrosion resistant and fireproof area is significantly larger than other kinds of compound shear wall, increase Construction costs;Effect of contraction of the shear wall framed with CFST columns due to steel pipe to pipe inner concrete, raising pipe that can be larger The comprcssive strength of inner concrete, internal concrete also delay steel pipe local yielding destruction occur.But it is main in Practical Project at present Two large problems to be had, first is to need to arrange shearing connecting piece between the concrete filled steel tube of end and wall body, and research shows that shearing connects Between the strong and weak and structural bearing capacity of fitting, relation substantially, which increases design and construction difficulty;Second is the constraint of shear wall Edge member length is relevant with wall limb length, axial compression ratio, seismic behavior, when confined boundary member is longer, common square steel tube Requirement can not be met, such as its effect of contraction to core space concrete can also be substantially reduced using rectangular steel pipe, and in steel pipe Wall sets up difficult with the connection measure of concrete.
