Abstract
Planning Truss rafter-shaped curves that support the placement of pints and roller-joints will affect the magnitude of the member forces and behavior of each member. In this paper, to find the magnitude of the member forces in each type of placement is to use the SAP 2000 V15 auxiliary program. The implementation procedure of this research is to collect data on each type of placement with the same load, so that the results of the member forces can be used as a reference for analysis. From the analysis and data processing, it can be concluded that for the placement of the roller-joints with right angle dimensions 2×60.60.6 and 2×50.50.5 do not meet the requirements, it is necessary to change the dimensions to 2×80.80.8, 2×70.70.7, 2×60.60.6 and 2×50.50.5. The placement of pints with 2×60.60.6 and 2×50.50.5 in right angle dimensions meet the requirements. But on the implementation, need to be mounted support beam between the trusses, caused at the bottom of the member, there is a compressive press force that resulted in the Kip, while the top side of the kip has been retained by rafter. For truss with roller-joint placement, no need to add the support beam because the tensile force occurs on the bottom.
