A system for building-specific multi-peril risk assessment and mitigation is disclosed. The system comprises a multi-peril hazard module, a processor, a database and a graphical network module. The multi-peril hazard module is configured to obtain hazard information and create a multi-peril event catalogue configured to generate intensity measures for multiple perils. The processor is configured to derive a peril vulnerability function and determine building-specific risk assessment results based on the hazard information and the peril vulnerability function. The database is configured to store the derived plurality of peril vulnerability functions. The graphical network module is configured to create probabilistic networks, wherein the probabilistic networks are connected to the determined building-specific risk assessment results of the peril vulnerability functions that have strong interdependencies and determine a multi-peril risk associated with the building.

System for building-specific multi-peril risk assessment and mitigation

A building structure including a plurality of elements extending from a ground surface with at least a first of the elements connected to a second of the elements by a coupling member, the coupling member including a damping element for damping vibrations in the building structure and a means for limiting the deformation of the damping element when the relative movement exceeds a maximum displacement at which damage occurs to the damping element.

Dual-phase vibration damping building coupling member with lock-up

A method for seismic loss assessment including receiving by a computer system computer-readable input data regarding a seismic hazard and building conditions, generating by the computer system one or more mitigation options and for each of the mitigation options, configuring the computer system to: determine a structural response, determine damage states from the structural response, determine an outcome of each of the damage states; and, output a representation of each of the outcomes for each of the damage states. The output is used in a seismic risk mitigation plan and/or design for one or more building structures.

System and method for earthquake risk mitigation in building structures

A building structure in an outrigger configuration having a building core, at least one perimeter column, and at least one outrigger beam having a main body portion connected to the building core, an end portion distal from the building core in a direction of the at least one perimeter column and a vane portion extending from the end portion. At least one damper having a high-viscosity fluid container connected is connected to the at least one perimeter column and the vane portion extends into the high-viscosity fluid container to couple the building core to the at least one perimeter column, such that when the building structure is subjected to lateral loads and the building core is displaced with respect to the at least perimeter column, high-viscosity fluid within the high-viscosity fluid container is sheared by the vane to damp vibrations and provide coupling in the building structure.

Viscous wall coupling damper

A building structure including a plurality of vertical elements extending from a ground surface with at least a first of the vertical elements connected to a second of the vertical elements by a coupling member, the coupling member includes a damping element for damping vibrations in the building structure resulting from relative movement between the first and second vertical elements due to lateral loads applied to the building structure. The damping element undergoes deformation due to the relative movement between the vertical elements causing the damping material to be activated in shear. At least one of a first and second fuse member is connected to at least one of first and second ends of the damping element respectively. The fuse member is selected from a material, and otherwise sized and dimensioned to exhibit semi-rigid behavior when the damping element undergoes deformation due to loads below a predetermined load limit and to undergo deformation without substantially increasing the load in the fuse and in the damping element when loads exceed the predetermined load limit, such that the damping element is prevented from deforming beyond its predetermined deformation limit and therefore avoiding any occurrence of damage that would reduce its ability to provide damping to the structure. First and second connecting means are also provided for rigidly connecting the first and second fuse members to the first and second vertical elements, respectively.

Coupling member for damping vibrations in building structures

A damping system including a first set of plates having one end thereof attached to a first vertically extending structural element, a second set of plates having one end thereof attached to a second vertically extending structural element spaced in a horizontal direction from the first vertically extending structural element, and arranged such that the first set of plates has a second end portion extending towards and overlapping with a second end portion of the second set of plates at an overlapping region, and further including an energy dissipating material provided in the overlapping region for connecting the first set of plates and the second set of plates.

Fork configuration dampers and method of using same

A new configuration damper, for interconnecting two elements of a structure that undergo relative movements and deformations, that increase the level of damping when the overall structure is subjected to a loading condition is disclosed. The new configuration damper aides in controlling displacements, velocities and accelerations under dynamic loading in structural systems.
