Experimental study of columns partially filled with concrete under compressive axial loads Etude expérimentale des colonnes partiellement remplis par le béton sous charge axiale

摘要: In the present work, results of tests conducted on thin welded steel-concrete stubs are presented. A total 24 an I steel section were tested under axial compression at 28 days after date casting, 4 empty, filled with normal concrete, 8 columns had shear connecters along centreline web, and rods between tips opposing flanges both sides spacing transverse link 100 mm 50 mm. The main parameters studied were: heel height, type connector strengthening. From test results, it is confirmed that walls more sensitive to appearance local buckling length profiles has a significant effect bearing capacity failure mode. was increased addition strengthening connectors.
