direction, whereas it keep its rigidity in the other direction. Corrugated steel is a type of building material composed of sheets of hot-dip galvanized mild steel, cold-rolled to produce a linear corrugated pattern in them. The corrugation shape increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them. Corrugated steel is lightweight and can easily be transported.

Abstract - In many situations, lighter steel structures are

used to the heavier alternatives such as reinforced concrete or prestressed concrete. With the growth of steel as a construction material, varieties of steel sections were also increased. Among these sections, the Hollow structural sections (HSS) or Structural hollow sections were the foremost reliable one. Hollow structural section is manufactured from a type of metal profile which consist of a hollow tubular cross section. The wide use of thin-walled steel structural systems in the construction industry is greatly indebted for their high strength to weight ratio attributes and remarkable fabrication versatility. Corrugated plates comes under this category have a wide range of application in various engineering fields. They are lightweight, economical, and have much higher load carrying capacities than flat plates, which make sure their popularity and have attracted research interest since they were introduced. In current project, corrugated columns are placed in different positions to determine the best and worst model in performance wise and then the worst model is strengthened externally and internally to improve their seismic performance. This project is done by using ETABS software.

1.1 Corrugated plate Corrugated steel is a building material consists of sheets of hot-dip galvanized mild steel, which is cold-rolled to produce a linear corrugated pattern. The corrugated plates are also known as self-strengthened plates. They are regularly produced from flat plates. The corrugation shape increases the bending strength of the sheet in the direction which is perpendicular to the corrugations, but not parallel to them. Normally each corrugated sheet is manufactured longer in its strong direction. The profile of a corrugated plate may have different shapes: triangular, trapezoidal, sinusoidal and rectangular

1. INTRODUCTION

The corrugated plates are regularly produced from flat plates. The most common profiles used for corrugation are trapezoidal and sinusoidal profiles. In this research, trapezoidal profile is chosen because it exhibits more ductility and higher bearing capacity compared to sinusoidal profile. Trapezoidal corrugated plates used in this study. The geometry dimension of corrugated plate is given in Table 1

Nowadays steel structures becomes more popular than concrete structures. Light weight steel or cold-formed steel seeks more attention from researchers as it is easy to handle, economic and have higher load carrying capacity than concrete. With the increased use of steel, the varieties of steel sections are used. The Hollow structural sections (HSS) or Structural hollow sections were most valid one. Members of hollow structural sections can be circular, square, or rectangular in sections. Corrugated plates fall under this category and also have a wide range of application in various engineering fields. The main advantages of corrugated plates are, they are lightweight, economical, and have much higher load carrying capacities than flat plates, which ensure their acceptance and have attracted research interest since they were introduced. The corrugation shape provides stable and continuous stiffening which permits the use of thinner plates. A corrugated plate can be effortlessly bent in one
