The bearing wall high-rise buildings
(57) Abstract:The invention relates to the construction, namely the high-rise buildings with load-bearing monolithic walls. The purpose of the invention is the control of rigidity bearing walls at the height of the building, increasing the durability and efficiency (energy intensity) work the wall. Known wall with slits, the slits are adjustable in their position along the height of the building for the same stiffness. New in the proposed retaining wall high-rise buildings is the fulfillment of the walls with slits through the floor and variable stiffness in proportion to the plot of shear forces from seismic (wind) loads, while the slots are cut with protective layers and placed them in elastic-plastic elements. 3 Il. The invention relates to the construction and can be used in earthquake-resistant construction of multi-storey buildings.Known wall construction consisting of an elastic frame and prefabricated load-bearing wall elements with vertical slits connected to the frame. When the application of the horizontal load each element of the wall with slits works as hard frame design with great elasticity. Under the application of a large seismic array is closer to the proposed invention the technical essence is the construction of the wall of the building, made of precast concrete wall panels, with the device of cracks, pits, seams, voids, miamature zones. The connection of the panels with a rigid frame, with sufficient strength of the walls of the gap for normal loading conditions. Under seismic loading is the destruction of the weakened parts of the walls, after which there is a gradual decrease in the strength of walls and complete loss of strength of the walls occurs after a complete loss of strength of the supporting frame (application Japan N 45-24104, E 04 2/02, 1970).The disadvantage of the solution is low-strength sections peremychechnyj zones between adjacent vertical slots on the perception of vertical shear forces, a constant (the same) the stiffness of the wall height of the building. Running through slots reduces sound quality walls, and replacement of the slots on the weak unreinforced concrete (miamature) zone leads to their destruction, as fragile, without elastic-plastic deformations. The location of the slots on each floor limits the height of the cross section Paramakatoi zone and the height of the slots, which reduces the effectiveness of this structure, which is provided under the condition that the destruction of the walls between the slots danielzyk cost of reinforcing (strengthening).The purpose of the invention, the control of rigidity bearing walls at the height of the building, in proportion to plot horizontal shear forces, increase strength peremychechnyj zones and increasing efficiency (energy intensity) work walls on the perception of seismic (wind) loads.This objective is achieved in that the bearing wall high-rise buildings, including vertical slits within the height of the floor and shelves for bearing slabs made with vertical slots through the floor with different size steps, which have a maximum value in the lower floor and a minimum at the top, with the slot running across the width, the smaller the thickness of the wall, with the formation of protective layers and placed them in elastic-plastic elements, perceiving shear (along the slit) forces.The proposed solution meets the criterion of "significant differences" as the patent information search found no signs, similar to the distinctive.In the proposed technical solution is the new feature is the implementation of the walls with slits through the floor, and the step of slots is defined as the maximum in the bottom is ximala below minimum and above), in proportion to plot horizontal shear forces and increased strength peremychechnyj areas due to the increase of the cross section of the floor. Execution of the slots with the device protective layer with elastic-plastic elements for perception shift increases the quality of performance of walls and soundproofing. Increased flexibility of walls walls (between slits) in height increases the intensity of the wall due to the exclusion of concentration pliability and spread across the entire height of the wall in proportion to the plot of shear forces.Thus, when a new set of known solutions obtained qualitatively new solution wall with variable stiffness along the height and increased energy consumption, increasing efficiency, reliability and seismic stability of the wall reduces the seismic load and accordingly, the consumption of steel in its reinforcement.In Fig. 1 shows the bearing wall; Fig. 2 a fragment of the slits with reinforced protective layer; Fig. 3 a section along the section of wall with the slot.The bearing wall high-rise building consists of reinforced concrete walls 1, divided by the slits 2, across the floor, solid walls 4, with 3 shelves, bearing plates and floors. On the ends of the slits 2 the implementation of the bearing walls of multi-storey buildings is as follows: the walls are in krupnomolotoy or other formwork, in which through the floor elements installed inserts for education of the slots 2 of an elastic soft material, slightly resisting shear walls 1, the ends of the elements insertions (protective layer) installed wire mesh 5. After concreting the walls and resolubilize elements inserts remain in the body wall, the length (height) of the slots is taken across the floor height. A positive effect in comparison with the prototype is achieved by the fact that the vertical load from the floor and its own weight of the wall is perceived by a section of the wall, and the horizontal (seismic, wind) load is perceived by parts of the walls with slots, as more malleable, subject to shear deformation and absorb the energy of the seismic action. Given that the cross-section of walls walls with slits decrease the height of the wall in proportion to horizontal shear loads, energy absorption occurs uniformly (equally) over the entire height of the wall, which increases the energy intensity (efficiency) work the wall and consequently its reliability and seismic stability. Performing in places cuts reinforced protective layer provides elastic-plastic work in the perception versa wall of high-rise buildings, made with vertical slits within the height of the floor and having a shelf for supporting slabs, characterized in that the vertical slits placed through the floor with a consistent reduction of the spacing between the slits from the lower to the upper floors, and the slots are cut in the width, the smaller the thickness of the wall, with the formation of protective layers that have elastoplastic elements for perception directed along the slots efforts.

Wall ribs have rounded upper and lower edges and may stably swivel along grooves created in horizontal panels during earthquake, wherein said walls are arranged between the panels. Rounded wall and rib edges have varying curvature so that said curvature is used as engaging and disengaging links and limit large displacement along with retention of seismic force reduction properties of the walls. Building comprises independent ribbed walls installed on two levels and intermediate horizontal panel arranged in-between. The horizontal panel is solid or provided with orifices or is made as crossing beam system. Walls and ribs thereof have rounded edges with varying curvature, which create cylindrical rolling surfaces to increate mutual contact areas and decrease stress concentration in walls. Walls of each level may swivel only in longitudinal and transversal directions with respect to building orientation so that wall displacement vectors in upper and lower levels are transversal one to another.
EFFECT: increased seismic resistance and reliability, possibility to withstand broad frequency spectrum earthquakes, elimination of stress concentration.
