Structural Condition Assessment of Steel-Framed Maintenance Plant in Muara Badak, Balikpapan, East Kalimantan

Abstract:

Structural condition assessment was conducted to a single-story, steel-framed maintenance plant. The assessment procedure aimed to ensure safe and sound operation of the existing structure, to determine its remaining service life as well as to propose the appropriate remedial actions for the existing structure. The assessment was performed through visual observation, Non-Destructive Testing (NDT), field load testing, also by carrying out structural analysis upon verified structural model. Corrosion and buckling are the main types of deterioration found within the structure owing to high salinity and slender steel sections. Structural analysis gave maximum stress ratio of 0.374. Static load testing resulted in deflection value of 17 mm, while dynamic load testing resulted in dynamic amplification factor of 1.06. In conclusion, the existing structure is considered to be structurally safe and sound with remaining service life of approximately 36 years and subjected to structural maintenance and strengthening.
