Polyurea coating helps improve the ductility and toughness of structural members. A fiber-reinforced polyurea (FRPU) composite\nprovides high load-carrying capacity and is applied by simply spraying it onto the member surface. Unlike existing reinforcement\napproaches, the FRPU coating method can prevent the ductility of concrete beams from deteriorating and the concrete surface\nfrom debonding.............................
In the freight railway bridge, the increase of the train running speed and train axle loads can enlarge dynamic response (DR) of the\nrailway bridges, which leads to excessive vibration of bridges and endangers the structural safety.........................
The Bohai Sea is the sea area with the worst ice condition in China, and the ice loads significantly threaten the safety of structures\nin the sea. The intense vibrations of the pile-supported bridge under stochastic ice loads will increase the fatigue damage of a\nbridge structure and reduce the fatigue life of a bridge structure.............................
A new type of explosion-resistant biomimetic layered honeycomb structure was designed based on the natural mechanism and\nbiological inspiration, which was mainly composed of a sacrificial layer and a bearing layer...........................
The effects of Reynolds number (Re) and surface roughness on the wind pressure coefficient on a MAN type dry gas tank were\nanalyzed in detail by wind tunnel tests. A wind load calculation model was then established, which is suitable for the wind resistant\ndesign of the gas tanks................................
