| Abstract: |
Safety during earthquakes should be a human right and shall be accessible not only to those who can pay for proprietary high-tech devices but to everyone. Based on that, this paper presents a low- cost, low-tech seismic energy dissipation device. Its experimental behaviour under seismic loading is assessed. The device is classified as buckling-restrained brace (BRB) and, according to its characteristics, it is suitable for new and existing, medium- to low-rise structures. First, the device composing parts are presented. Then, its structural response, in terms of hysteretic behaviour, ductility, and dissipated energy – as obtained from experimental tests – is shown. Experimental results show an excellent behaviour. As a result, it can be said that the device is reliable and its use is recommended for new and existing structures. Design recommendations are also provided. |
