Experimental Analysis of Axially Loaded Aerated Mortar Filled Tubes
Keywords:Aerated mortar filled steel tube, Buckling mode, Yield strength and Energy absorption capacity, Compressive strength, Compression test
This study present, an experimental work on axially loaded aerated mortar filled steel tube in axial compression. The main objective is that to determine maximum load carrying capacity of aerated mortar filled steel tubes and detailed study on the behavior of steel tubes. From the experimental investigation, it was concluded that an empty tube shows concertina mode of failure where as in normal
mortar Euler buckling mode failure was observed. It is concluded that Energy absorbing capacity of steel tubes is increased by filling the tubes with aerated/normal mortar and the order of increase is about 64% when filled with aerated mortar and as high as 176% when filled with normal mortar.
