Description
Technical field
The utility model belongs to the combining structure of building field, relates to a kind of novel combining structure form, is specifically related to a kind of Semi-rigid Connection Steel Frame inside and builds in the steel frame that ductility high performance concrete (ECC) forms and fill out ECC shear wall combining structure.
Background technology
Along with economic prosperity and scientific and technological progress, highrise building has become the symbol of a city even a country.Advantages such as steel framed structure has flexible arrangement, and ductility is good, and the space is big are used more in highrise building.But the anti-side rigidity of steel frame is little, and distortion requires the turning power height to node greatly under rarely occurred earthquake.For improving the endurance and stiffness of steel frame, this combination construction system of steel frame concrete filled shear wall (SRCW) is developed.Steel frame bears most of vertical load and overturning moment in this system, fills shear wall and bears most of shearing, has effectively utilized the advantage of two kinds of materials to a certain extent.But because inner concrete shear force wall rigidity of filling is bigger, shear brittleness takes place easily destroy, concrete filled is in case cracking causes bearing capacity of wall body and rigidity to descend significantly, the shearing that this moment, structure was born is born by steel frame, makes structure reach collapse state rapidly.As seen, though steel frame concrete filled shear wall structure has increased the rigidity of steel framed structure, but fail to give full play to the advantage of steel and these two kinds of materials of concrete, seeking ductility is good, energy dissipation capacity is strong packing material, to improve the stress performance of this combining structure significant.
There are some researches show, ductility high performance concrete (ECC, Engineering fiber reinforced Cementitious Composites) is a kind of high tenacity concrete, has very big endergonic ability, can significantly improve the anti-seismic performance and the shear behavior of concrete shear force wall.Under the axial tension load, the load-deformation curve of ECC material shows tangible strain hardening feature, before test specimen destroys, present and many fine and closely woven cracks occurred, its limit tensile strain can reach more than 3%, is more than 100 times of ordinary concrete, is more than 10 times of reinforcement yielding strain; Be unworthy of under the situation of shear reinforcement, the ECC beam exceeds about 0.5 times than reinforcing bar normal concrete beams bearing capacity, and deformability improves more than 2 times; The ECC plate can show the buckling phenomenon as steel when being subjected to bend.This shows, the bending resistance of ECC excellence, shear behavior and steel comparison match, the ECC shear wall is used for steel framed structure, can increase the lateral rigidity of steel framed structure, improve the plastic deformation ability of shear wall, alleviate the destructiveness of steel frame node, improve structural seismic performance, have most important theories meaning and construction value.
Summary of the invention
