Analytical study on pad footing foundation design usingcold-formed steel lipped channel section

This paper presents the structural performance of the proposed prefabricated pad footing foundation using BRC as reinforcement and Cold-formed Steel Lipped Channel Section as permanent formwork. Steel bars or mesh has been used traditionally in reinforced concrete. Cold-formed Steel has the advantage of higher yield strength as an effect of cold working, plus its pre-galvanised metal has high resistance to corrosion. However, the use of Cold-formed Steel Lipped Channel Section for prefabrication of pad footing structures is yet to be established. Investigation has been carried out by examining the structural performance of both the proposed and typical footings. Experimental tests of 3 typical and 3 proposed pad footings were carried out in Structural and Material Lab, UTM. Comparison on the failure mode and ultimate load was made between the two set of specimens. The results shown that the proposed pad footing performed better compared to typical footing. It is concluded that pad footing foundation designed using Cold-formed Steel Lipped Channel Sections is feasible for construction.
