Assessment of the structure of public elementary school 28 Air Tawar Timur Padang

Abstract

The Public Elementary School 28 Air Tawar Timur Padang was built in 1982. The current condition of the school building is damaged, such as cracks, spalling, deflection, and shaking floors. This study aims to provide recommendations for the repair or maintenance of the building. The assessment method used in this study is the Non-Destructive Test method by using a Rebound Hammer, Rebar Locator, and Calliper. Testing the building geometry and deflection slabs using Total Station and Laser Measurement. The building structure was analyzed using the SAP2000 Version 16. The results of the concrete compressive strength test (FC) are 20.40 MPa on the column, 22.23 MPa on the beam, and 23.43 MPa on the slab. The results of visual observations of the building are categorized as severely damaged with a proportion of damage above 20%. The proportion level of column damage is 32%, beams 20.35%, and the floor court is 65%. The results of the building structure evaluation show that all elements are categorized as unsafe except Beams 3, 4, and Column 2. The maximum deflection of the slab as high as 73mm exceeds the allowable permit, which is 18.9mm. The recommendation for the repair of the school is building renovation.
