Experimental investigation of mechanical behaviors of EPS foamed concrete-filled pultruded GFRP sandwich panels

Pultruded sandwich panels (PSPs) usually possess lightweight but high load-carrying ability. One of the shortcoming is the low transverse shear resistance. To overcome this deficiency, Expanded Polystyrene (EPS) foamed concrete was designed, fabricated and filled into the web-core of the PSP. Flatwi...
