The Effect of Using Composite Column for Enhancing Structural Stiffness

Abstract

The aims from this study is to determine which story has the greatest effect on the structure by using a structural column from composite material that is consist of steel and concrete combined together. Using the help of MIDAS GEN software to do the structural analysis. 5 models were made to capture the lateral displacement due to earthquake loading using linear dynamic procedure. Model 1 is a steel only structure followed by next model using composite materials starting from the bottom 2 floors (model 2 ), 4 floors (model 3), 6 floor (model 4), all floors (model 5). From all of the models that is used, we can conclude that the bottom 2 story is the one that has greatest impact in lowering the lateral displacement.
