Damping Systems

Structural control systems, including passive, semi-active and active damping systems, are used to increase structural resilience to multi-hazard excitations. While semi-active and active damping systems have been investigated for the mitigation of multi-hazard excitations, their requirement for real-time controllers and power availability limit their usefulness. This work proposes the use of a newly developed passive variable friction device for the mitigation of multi-hazard events. This passive variable friction device, when installed in a structure, is capable of mitigating different hazards from wind and ground motions. In wind events, the device ensures serviceability, while during earthquake events, the device reduces the building’s inter-story drift to maintain strength-based motion requirements. Results show that the passive variable friction device performs better than a traditional friction damper during a seismic event while not compromising any performance during wind events.

Composed wall with site laying reinforcing rib is composed of reinforced concrete rib, girtstrip and filling brickwork. This kind of wall is energy-saving, environmental-friendly and of good earthquake resistant performance. It is suitable to village building structure. In this paper, the load carrying capability and failure mode of this kind of composed wall under the effect of vertical load, the maximum bearing capacity of the wall and its influencing factors are mainly introduced.
