Cold-Formed Steel-Concrete Beams
Abstract: Light weight
material usually be chosen as a material for earthquake resistant building in
order to reduce inertia force of the building. In comparison with others
section, a cold-formed steel section is a lighter section and makes this
section is categorized as a light weight material. During reconstruction of
Yogyakarta earthquake of 27th May 2006 some housings were
constructed by using cold-formed steel sections. However, investigation on the utility
of cold-formed steel section for structural elements was very limited. Two
experimental programs of cold-formed steel-concrete beams were carried out. One
of the experiment used normal weight concrete and the other used light weight
concrete. In the experimental programs, the normal weight concrete had the
compressive strength of 23.53 MPa, while the light weight concrete had the
compressive strength of 12.91 MPa. This paper tried to analyze and compare
those experimental programs. The comparison showed that the cold-formed steel beam
with normal weight concrete gave higher load capacity than the cold-formed
steel beam with light weightconcrete. However, if the comparison was taken with
respect to the ratio of compressive strength to density, the cold-formed steel
beam with light weight concrete might give more promising bending elements for
earthquake resistant building.
