Cyclic Behaviour Of Double Skinned Concrete In-filled Beam-Column With Outer Cold Formed Square section and Inner PVC Circular Sections

Abstract

Study is done to compare the lateral load capacity, ductility and weight of double skinned light gauge in filled
column with outer square and inner PVC section and concrete filled light gauge steel tubes. The test is done with the help of
lateral load testing frame. The reversed lateral loads have to establish so that the frames experiences substantial inelastic
deformation in tension and compression in the presence of axial compressive loads. Specimens are in filled with M30 grade
concrete. Four specimens are tested, out of two are control specimen and rest two are testing specimens. Control specimens
are those with concrete filled light gauge steel tubes and test specimens are double skinned light gauge concrete in filled
column. Height of the column are 1000mm and of 100mm×100mm size. Based on the test results lateral load capacity of test
specimen increased by 10.6% compare to control specimen, ductility increased by 13.77% compare to control specimen and
weight decreased by 16.07% compare to control specimen. So the double skinned light gauge sections are more economical
ad can be effectively use in seismic regions due its improved characteristics.
