Abstract

<p> To ensure the seismic resilience of bridges with a low-cost solution, a novel friction isolation system has been developed based on the traditional friction pendulum system. The proposed system possesses a spherical flat-inclined concrete surface with the aid of three-dimensional (3D) printer. Concrete surface was lubricated with resin material to prevent abrasion from multiple-input ground motions. In this study, size effect on the dynamic behavior of the proposed bridge under bidirectional ground motion was investigated by shaking table test. Experimental results demonstrate that independent of specimen size, response acceleration reduction and small residual displacement could be observed due to the combination of flat and inclined shapes. In addition, simplified method to estimate seismic demand (i.e. maximum response displacement and residual displacement) of proposed system was presented.</p>
