three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

Abstract Applications of sandwich composites are increasing as they continue to develop. The reason for the growth in development and rising demand numerous industries is due its ability achieve high stiffness strength, while simultaneously being lightweight comparison traditional materials. 3D printed plastic hollow core were focused on this study where a bioplastic, Polylactic Acid (PLA), was...

Wood–plastic composite (WPC) materials are mainly used as flooring in buildings or structural load-bearing plates, and will undergo creep deformation during use, resulting failure safety problems. Therefore, this work adopted the orthogonal test method to carry out tests on wood–plastic composites. We range variance analysis process data analyze influence of load, temperature, relative humidity...
