Abstract |
The purpose of this study is to experimentally evaluate the structural behavior of built-up type column consisted of angles and y-shape steel sheet forms for filling concrete. This column for minimizing form working and reinforcement placing is able to improve capacity of construction and reduce the term of works. Thirteen 1/3 scaled columns were fabricated. The main variables are 1) effect of angles and y-shape steel sheets of fabricated columns, 2) slenderness of column, 3) eccentricity of column. The results show that the experimental capacity of built-up type column is similar to theoretical one by reinforcement concrete design code. The maximum loads increase according to the rate of angle to cross section of column.
