STRUCTURAL REDESIGN OF BETHANY YESTOYA CHURCH BUILDING MALANG USING COMPOSITE STEEL–CONCRETE SYSTEM

Abstract

Bethany Yestoya Church building is a place of worship located in Malang City. Bethany Yestoya Church building is planned using reinforced concrete structure. Structural modifications are planned using steel – concrete composites. Modifications are planned to make the smaller and more practical structural dimensions, so that they will increase the aesthetic value of the building. Calculation analysis carried out on the modification of the composite steel concrete structure obtained results for the secondary structure, plate design with a wave steel deck with a plate thickness of 15 cm, the small beam profile was used WF 390.300.10.16 and the bordes beam WF 250.125.6.9. The structure produced in this plan is obtained by main beams using the WF 500.200.10.16 profile and columns using the WF 450.200.9.14 steel profile covered in concrete with dimensions of 600 mm x 600 mm. The redesigned and modified structure has required safety standards and is deemed safe for occupancy or building.
