LRT is an alternative means of mass transport modes of rail aims to reduce the number of vehicles on the highway. LRT planned structure has a height of 9-13 meters above the ground by using U-Shape Girder consisting of two lanes with a width of 9.45 meters and a span length between spans 30 meters. LRT planning structure begins with the collection of technical data needed such as span length, the width of the road and the load acting on the structure of the LRT. Then proceed with the basics of the structural design of the LRT which refers to the Ministerial Regulation No. 60 Year 2012 and SNI T-12-2004. In the early stages of planning to do modeling circle column design and continued analysis of the load acting on the structure LRT C1TM137-C1TM140, then the calculation results of the analysis carried C1TM139-C1TM138 column structure with landscape and the different dimensions of the design of the original plan, the work load analysis calculations used computer applications. The results obtained have different column structure that spans different cross sections and dimensions affect the structural reinforcement of the column. The final results obtained in the form of a square column dimensions rise to circle column dimensions of 21.395% for diameter ?2300mm and amounted to 1.201% of the diameter of a square cross-section ?2100mm and column dimensions 1850x1850mm more effective in reinforcing the structure of the column. The results obtained have different column structure that spans different cross sections and dimensions affect the structural reinforcement of the column.} }
