Description
Technical field

Background technology
Shear wall structure and frame-core tube Mixed Architecture are the form of structure generally adopted in high-rise and super highrise building at present.The beam of connection wall limb and wall limb, wall limb and frame column is called coupling beam.It is little that coupling beam generally has span, and cross section is large, the feature that the wall stiffness be connected with coupling beam is very large.Because building doors and windows punches or structure design demand; usually Coupled Shear Wall can be adopted; coupling beam and wall limb ratio of rigidity should be moderate, and it changes the couple that is made up of the bending resistance of each wall limb and wall limb axle power into resist horizontal force by the cross section bending resistance that only relies on of entity shear wall.Coupled Shear Wall reasonable in design mainly relies on bottom coupling beam end and wall limb and occurs that plastic hinge is to the seismic energy that dissipates, and coupling beam is introduced into surrender, coupling beam is as the main dissipative member in shear wall structure, because its internal force under geological process is larger, and comparatively large on the impact of wall limb, make it in the anti-seismic performance research of shear wall, have critical role.
Usual employing be still reinforced concrete coupling beams, when the rise-span ratio of conventional steel bar concrete coupling beam is less (being generally not more than 2.5), the shear failure in concrete rupture district can be there is in coupling beam after vertical muscle surrender, ductility and energy dissipation capacity poor, along with the increase of cutting pressure ratio, the ductility of coupling beam can reduce further, and increases the shear failure that stirrup can postpone coupling beam to a certain extent, but limited use.
In order to improve ductility and the energy dissipation capacity of the reinforced concrete coupling beams of small span-depth ratio, U.S. ACI318-08 specification and China's " seismic design provision in building code " regulation: when the span-depth radio of coupling beam is less than 2, intersection concealed bracings arrangement of reinforcement coupling beam should be used, although concealed bracings arrangement of reinforcement coupling beam of intersecting has had larger lifting than conventional steel bar concrete coupling beam in ductility and energy dissipation capacity, but load in the plain bars skeleton of coupling beam executing after man-hour requirement runs through two oblique cage of reinforcement mutually, construction bothers very much.In order to enable coupling beam effectively dissipate seismic energy, propose to adopt steel coupling beam to substitute the thought that reinforced concrete coupling beams carrys out connecting reinforcement concrete shear force wall.
Steel beam column is adopted usually to have two kinds as the way of Coupled Shear Wall energy-consuming parts: reinforced concrete coupling beams is replaced with steel coupling beam by (1); (2) reinforced concrete coupling beams is replaced with shearing type damper.Way (1) steel coupling beam as structural element, and can only remain on elastic stage under little shake, can not provide additional damping ratio for structure, the effect of its competence exertion energy-dissipating and shock-absorbing under middle shake or large shake; Way (2) is actually the additional energy-dissipating device of shearing type damper as structure under little shake, for structure provides additional damping, thus reduction geological process, but can not structural element be it can be used as, being coupled than the anti-side efficiency with structure of Coupled Shear Wall can be affected.
Utility model content
Technical problem to be solved in the utility model is exactly for existing coupling beam above shortcomings, one is provided to utilize shear plate yield displacement less, the feature that perforate bent stick yield displacement is larger, realize the steel coupling beam of the function of surrender power consumption of two stage, and the distortion of two energy consume mechanisms and bearing capacity separate, not only easily design, and structure is relatively simple again, do not need to increase extra constraint mechanism, better economy, ductility and energy consumption is excellent.
For achieving the above object and other relevant objects, the utility model provides a kind of two rank power consumption steel coupling beam, at least comprise endosternum, two pieces of coxostermums, upper and lower frange plate and polyliths put more energy into floor, described two blocks of coxostermums and endosternum are parallel to each other and are vertically connected between top flange plate and bottom wing listrium, described endosternum is arranged between two coxostermums, be provided with multiple horizontal bar-shaped trough in the middle part of described endosternum, described outer web outside longitudinal separation arranges polylith and to put more energy into floor.
Further, described coxostermum is the low yield point steel plate of initial yield intensity lower than 235Mpa.
Further, the initial yield intensity of described endosternum is greater than pleurosternal initial yield intensity.
Further, the length of described horizontal bar-shaped trough is 1/3 of endosternum length.
By above technical scheme, the utility model has following technique effect compared to prior art: the utility model greatly can improve the ability of building structure opposing horizontal earthquake action, improve the anti-seismic performance of structure, after avoiding the shake of ordinary concrete coupling beam, repair the shortcoming of difficulty; The shortcoming of additional damping can not be provided under improving the little shake of ordinary steel coupling beam; Its structure rationally, make use of shear plate yield displacement less, the feature that bent stick yield displacement is larger, can realize the function of surrender power consumption of two stage, and the distortion of two energy consume mechanisms and bearing capacity separate, not only easily design, and structure is relatively simple again, do not need to increase extra constraint mechanism, better economy, ductility and energy consumption is excellent, has good popularizing application prospect.
