Analisis Destruction Test Tower Sutet dibandingkan dengan Software Ms Tower dan SAP 2000

The transmission line system which is currently growing rapidly in Sumatra, requires a reliable interconnection network to meet the electricity demand for West Sumatra region. PT. PLN as provider of businesses Indonesia conducted planning and destruction tests design new model Extra High Voltage Transmission Line (SUTET) tower with specification 66.6 meters height, slim type tower, 275 kV, lattice BB+15, quadrapole zebra (435/55 mm2) 2 cct. This research aims study collapse behavior caused by working loads, analyze compare suitability level deformation natural frequency among MS Tower, SAP 2000 space truss analysis, frame analysis test results. shows that unstable Leg section. mode shape close value deviation 30%. occurred due imperfection geometry on legs section, resulting global collapse. Improvements form adding equal angle hip bracing were carried out, result was able withstand load case 9870 up 100%. Space closer this can be seen from values approach each other two analyses.
