Abstract

See full text

The present invention relates to a variable friction energy dissipation prefabricated seismic-damping partition wall-frame structure and a construction method therefor. The variable friction energy dissipation prefabricated seismic-damping partition wall-frame structure includes a peripheral frame, prefabricated seismic-damping partition wall panels, rubber pads, a friction seismic-damping layer, horizontal force transfer members and a steel angle restraining members. The sliding friction of the partition wall can be significantly improved with increase of an inter-story drift, so that the partition wall has a larger hysteretic area and a higher energy dissipation capacity and can provide the structure with a relatively high additional damping ratio, so as to alleviate a seismic action. In addition, integral damage control of the partition wall can be better achieved, and the energy dissipation capacity of the partition wall under bidirectional seismic actions can be guaranteed.
