Definitions

  • THE present application describes dissipator panels for seismic reinforcement of building structures, including those consisting of resistant walls of masonry and wooden floors and heritage buildings, and relates to the respective constructive system.
  • the cage is comprised by triangular inner walls with pombaline front, also known as pombaline frontals or simply by front and by the wooden structures of floors and roofing. Besides the latching function of the resistant stone masonry exterior walls, the front used to serve as a floor support and as partition walls [1].
  • the dissipator panels referred to in the present patent object correspond to a system that allows improving the structural safety of buildings against seismic action, thus reducing damage resulting from the referred action over the buildings.
  • the new seismic protection systems allow maintaining the operability and functionality of constructions, immediately after the occurrence of high intensity earthquakes. They also ensure the protection of the contents, components, equipment and secondary structural elements of constructions [4,5].
  • the present application describes a dissipator panel that comprises the following elements:
  • the uprights of the dissipator panel are constituted by metallic or composite material profiles and are positioned vertically between the floors of the building.
  • the sleepers of the sink panel are constituted by metallic or composite material profiles and are positioned in the horizontal direction at the level of the building floors.
  • the uprights and sleepers of the sink panel form a square or rectangular flat structure, in which intersection of the diagonals the central dissipative device is placed and to which the diagonals, belonging to said sink panels, are connected.
  • the dissipator panel comprises a dissipator device connected to four diagonals, which in turn are articulated with the crossbars and the uprights by means of mechanical connections at the level of the floors.
  • the diagonals of the dissipator panel are positioned in the two diagonal directions of the parallelogram formed by the uprights and the crossbars.
  • the diagonals of the dissipator panel are built on metal or composite material.
  • the central dissipator device of the dissipator panel is hysteretic or viscous type.
  • the heat dissipator panel is fixed to the floors along its upper and lower contour.
  • the crossbars of the dissipator panel are placed symmetrically relative to the median plane of the structural system of the floors.
  • the present application further describes a seismic rehabilitation system of structures, comprising at least one dissipator panel as described above.
  • the present application further describes the building comprising at least one dissipator panel as described above.
  • This application discloses dissipator panels used for seismic reinforcement, allowing increasing significantly the energy dissipation capacity of the structures and hence improving the overall seismic behaviour of buildings.
  • the dissipator panels are comprised by a central dissipator device and by diagonals, uprights, crossbars and connections, the group of these elements forming an articulated flat structure.
  • the technology now presented reduces the seismic vulnerability of buildings.
  • the incorporation of dissipator panels on the structural system of the buildings is reflected in the reduction of the damages resulting from the seismic action.
  • the global seismic behaviour of the reinforced buildings relatively to non-reinforced shows a significant improvement, both in terms of effort, either in deformation, as well as an increase in the energy dissipation capacity.
  • dissipator panel enables significant improvements compared to the known solutions from the prior art, with regard to preserving the basic characteristics of constructions and safeguarding its historical and architectural value, in case of heritage.
  • the dissipator panels correspond to a slightly intrusive solution, compatible, easy to insert in the current structural systems.
  • the dissipator panels are slightly intrusive since they allow the realization of minimum interventions that are compatible and do not alter the original structural scheme, avoiding or minimizing the need for cutting or demolition of existing structural elements.
  • the dissipator panels constitute a solution with reversibility characteristics as they are installed so that they can later be removed or supplemented, if necessary, without great difficulty and without causing significant damage to the original construction.
  • the constituent elements of the dissipator panels that show any deformations can easily be replaced with new elements.
  • rehabilitation emerges as a relevant strategy, especially by allowing mitigation of impacts associated with interventions in existing constructions.
  • the rehabilitation makes it possible to reuse of existing buildings, mostly located in residential and/or urban areas urging to revitalize.
  • the social benefits also result from safeguarding cultural, architectural and historical values. Interventions should enable the maintenance of the buildings authenticity, without sacrificing all the relevant corresponding to the cultural and historical area from which buildings are part.
  • This application discloses dissipator panels used for seismic reinforcement, allowing increasing significantly the energy dissipation capacity of the structures and hence improving the overall seismic behaviour of buildings.
  • the dissipator panels are comprised by a central device dissipator and by diagonals, uprights, crossbars and connections, forming the group of these elements an articulated flat structure, such as illustrated in Figure 1 .
  • the uprights develop vertically between floors; the crossbars are positioned in the horizontal direction at the level of the floors.
  • the diagonals are connected to the central dissipator device and the other end thereof diagonals connections are established to the uprights and crossbars, at the level of the floors.
  • the dissipator panels are fixed to the floors along its upper and lower contour. Except in the case of buildings, whose structure of the floors does not allow it or if it is an end panel, the crossbars are double and are placed symmetrically in relation to the median plane of the thickness of the floors, pressing the constituent elements of these floors. The pairs of crossbars are thus connected together at the level of the floors.
  • the dissipator panels for seismic reinforcement constitute a prefabricated intervention solution, with behavioural characteristics well defined, easy to insert into current structural systems.
  • dissipator panels can be placed on one or more floors and in each floor can be placed one or more dissipator panels.
  • the dissipator panels can be annexed to interior walls. On the sites of interior bays, continuity may be ensured by small rigid elements.
  • the dissipator panels correspond to reinforcing elements slightly intrusive, reversible and consistent with the structural mode of operation of the constructions, thus allowing to meet the requirements that should respond to interventions in old buildings, in particular, reduced intrusiveness and extent of interventions, reversibility and compatibility with the existing. Throughout this patent application, it is considered that the dissipator panels show reduced intrusiveness because they are panels that are slightly intrusive.
  • the central dissipator device belonging to the dissipator panel is comprehended by a polygonal piece of well-defined geometry, obtained from metal or composite material, e.g., steel, stainless steel, properly protected against corrosion steel or other equivalent material.
  • the uprights used in the dissipator panel are comprised by building profiles of metallic or composite material, positioned vertically between the floors of the building.
  • the crossbars used in the dissipator panel are comprised by building profiles of metallic or composite material, positioned horizontally, at the level of the building floors.
  • Diagonals used in the dissipator panel are comprised by construction profiles of metallic or composite material, positioned in two diagonal directions of the parallelogram formed by the uprights and the crossbars. These diagonals are destined to make the connection of the central dissipator device to the constituent crossbars and uprights of said dissipator panel.
  • Dissipator panels are used in seismic reinforcement interventions of buildings, aimed at increasing its seismic safety and therefore reducing its vulnerability.
  • the panels correspond to an easy insertion solution on current structural systems and enable, simultaneously, to perform interventions with reduced intrusiveness and extension, reversible and compatible with the existing.
  • the panels are slightly intrusive, do not adulterate the basic characteristics of the constructions, are compatible with their original structural mode of operation and its installation is reversible.
