This study examined structural behaviors of grout filled composite steel tube member, since grout-filled steel tube can improve its structural load resistance from enhancing strength, stiffness, and confining effect. To evaluated the effect of grout filling in the steel tube on its structural behaviors and strength, grout-filled steel tube specimens were fabricated and lateral loading tests were conducted. From lateral loading tests, their lateral loading resistance and stiffness were examined.
