COMPARATIVE STUDY OF INNOVATIVE CORRUGATED HOLLOW COLUMNS AND CONVENTIONAL COLUMN

Civil Engineering

In many situations, lighter steel structures are used to the heavier alternatives such as reinforce concrete or prestress concrete. With the development of steel as a construction material, the varieties of steel sections were also increased. Among these sections, the Hollow structural sections (HSS) or Structural hollow sections were the most reliable one. Extensive research has been carried of corrugated web beam and girders, but fewer amounts of research for corrugated column and its utilization and advantages is available. In current project, five types of innovative hollow steel section (HSS) column are designed; fabricated and tested. The present work is divided in two broad parts such that in the first part, the study of the behavior of the innovative corrugated steel column under axial loading using UTM was conducted, this part being called experimental work. In the second part, the results of the practical experiments are checked with theoretical results which are obtained by analytical method by using computer software ANSYS. The results obtained from experimental testing and computer analysis are compared and validated. The comparison of corrugated hollow column with conventional hollow column is done to know the advantages of innovative column over conventional column. Keywords: Corrugated hollow column, computer software, thin walled structures, innovative column, and conventional column.
