Mechanical behavior and failure of carbon fiber-reinforced composite sandwich structure inspired by curved-crease origami

Thomas Keller

Origami offers a novel design possibility for periodic sandwich cores. The curved-crease origami is adopted to enhance the anti-buckling performance and reduce the abrupt change of the carbon fibers in the origami sandwich cores. CFRP curved-crease origami ...

The Deformation Capacity of Lap Splices in RC Walls: From Experimental Testing to Numerical Modelling

Danilo Tarquini

Field observations as well as experimental tests have shown that both the strength and displacement capacity of reinforced concrete (RC) members might be significantly reduced by the presence of lap splices. This degradation applies in particular if the lo ...
