Steel column planning using the American Institute of Steel Construction (AISC) 2010 method

Abstract

The latest SNI rules for steel structure building has been published namely SNI 1729-2015 which refers to the AISC 2010. In AISC 2010, there is a new design method called Direct Analysis Method (DAM) as an alternative to the Effective Length Method (ELM). The aim of the study is to plan steel columns using the AISC 2010 method and calculate and also analyse the steel column capacity. In this study, ETABS computer analysis program that have been whole integrated includes the modelling, analysis and design were used, so as to produce safe and economical modelling, analysis and design. The results of trial and error showed that dimensions for the 1st and 2nd floor columns WF profile, 3rd and 4th floor columns used WF 250x250x9x14 profile, and the 5th floor column used WF 175x175x7.5x11 profile. The load that applied was only dead load and live load. ETABS analysis results obtained output in the column design in the form of axial force (P) 1688,971 kN, moment (Mux) 60,257 kN.m, moment (Muy) 23,009 kN.m. The calculation results of steel column design analysis using DAM method obtained the value of the ratio of the strengths of columns 1st and 2nd floors for 0.42, columns 3rd and 4th floors for 0.33 and the 5th floor for 0.15. The steel column material requirements for each 1st and 2nd floor are 352.66 kg, 2nd and 3rd floors are 271.35 kg, and the 5th floor is 150.75 kg. The design of steel columns by means of DAM results in a higher profile capacity, so that the profile designs used can be more economical.
