摘要:
A yielding fuse device is provided for use in association with a brace member in a bracing assembly for a structural frame. The device includes arms or elements that yield flexurally when a bracing member moves in an axial direction, with the bracing assembly under either tension or compression loading conditions. The device of the present invention is particularly useful as a mass customized cast device. The device is well suited for seismic bracing applications.
摘要:
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.
摘要:
A cast structural connector connects a structural member, such as a hollow structural section (HSS) or wide flange (W) section member, to a structural frame. The connector is particularly suited for lateral bracing and includes a first end configured to receive the structural member and be welded to the structural member, a second end for connecting to the structural frame, and an intermediate portion. The first end includes bevelling allowing compatibility with structural members of varying sizes and enabling complete joint penetration welding thereby developing the full axial strength of the structural member. The intermediate portion provides for transmission of forces as the frame deforms, for example, under severe seismic conditions, and can include a flexural plastic hinge portion. The connector can be welded to the structural frame or connected by a standard fabricated end connection, such as a gusset plate. Casting manufacturing allows for mass production of the connector.
摘要:
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.
