Member-to-member laminar fuse connection
A member-to-member planar connection bracket that includes multiple repeated fuse element configurations that each provide a pre-determined inelastic load-carrying capacity and a reliable inelastic deformation capacity upon development of one or more inelastic hinge locations within the fuse elements. The fuse configurations are interconnected in series such that the total deformation accommodated between first end of the bracket and second end of the bracket is the sum of deformations accommodated by the individual fuse configurations. Multiple brackets are configured in laminar configurations and interconnected to create a connection assembly that provides increased strength or increased deformation capacity as compared to an individual bracket. The connection assembly is used to connect a first structural member and second structural member. The pre-determined maximum inelastic load-carrying capacity of the assembly is less than the elastic load-carrying capacity of the first structural member and the second structural member.
ACTIVE INERTER DAMPER
This disclosure relates to an active inerter damper configured to be disposed on or in a building structure. The active inerter damper includes a base, a lead screw, a rotational mass block, a driving device and a controller. The lead screw is movably disposed above the base along an axial direction. The rotational mass block is engaged with the lead screw so as to be rotatable with respect to the base. The driving device is connected to the lead screw. The controller is electrically connected to the driving device, and the controller is configured to activate the driving device to move the lead screw along the axial direction so as to rotate the rotational mass block via the lead screw.
Building, in particular a multistory building, and use of a damper in such a building
The invention relates to a building (1), in particular a multistory building, which has a supporting structure (5), and a facade (3) which is operatively connected to the supporting structure and exposed to the wind, wherein the facade (3) has a plurality of facade elements (7), wherein the facade elements (7) are designed to move relative to the supporting structure (5) in reaction to a torsion of the supporting structure (5). It is proposed that at least some facade elements (7) are operatively connected to a number of dampers (13), wherein the dampers (13) are designed to damp a movement of the facade elements (7) relative to the supporting structure (5).
Earthquake stabilization device
A stabilization system for a building includes a weight assembly configured to be coupled to a floor structure of the building, a seismic sensor configured to provide measurement data relating to a seismic event, and a controller. The weight assembly includes a track defining a track path, a weight slidably coupled to the track, and an actuator coupled to the weight and configured to move the weight along the track path. The controller is operatively coupled to the seismic sensor and the actuator and configured to (a) determine a target response of the weight assembly that mitigates the effect of the seismic event on the building based on the measurement data, and (b) control the actuator to move the weight along the track path according to the target response.
Impulse tuned mass damper for tall, slim structures
An impulse damper device, which is specifically provided for the construction or the dismantling of tall, slim constructions, in particular towers and preferably towers of wind turbines, in order to minimize or eliminate undesired vibration states, which often occur during the construction or taking apart and lead to large increases in the vibration amplitudes of the vibration system. The impulse tuned mass dampers are preferably provided for temporary mobile use, but, in principle, are also suitable for permanent use.
