Abstract
Gedung Olahraga Setara Marabahan is one of the sports facility buildings built in Marabahan, South Kalimantan. During the construction of the Gedung Olahraga Setara Marabahan, the construction experienced inaccuracies, which resulted in the installation of steel columns. The steel column is not installed parallel to the centroid axis of the concrete column, which causes the concrete column to experience an eccentric load. The eccentric load can be divided into two types of loads: the centric axial force Pn and the bending moment Mn. The eccentricity of a cross-section has a significant impact on the load applied to that section; the eccentricity of the load also allows the column to deform in shape and position, such as the emergence of lateral deflections. Because it will have an impact on column collapse, which is a critical matter that needs to be taken seriously because column collapse will have fatal consequences for the construction that has been built. The analysis uses the planned and existing conditions of the building. The column cross-section size is 50x50 cm, the reinforcement used is 19 mm in diameter as the main reinforcement, and the stirrups are 10 mm in diameter with a spacing of 150 mm. The data used in this study used test and measurement data from the laboratorium structure and laboratorium survey FT ULM. The laboratory data is then processed using 3D analysis software to obtain the internal forces that occur at the structure's cross-section, followed by theoretical calculations. To get the crack pattern, FEM (finite element method)-based software is used. From the results of the analysis of the planned and existing building conditions, it is clear that the eccentricity that occurs in the existing conditions of the building experiences a greater moment increase compared to the planned building conditions. The increased moment results in a deflection, and as the axial load and eccentric distance increase, the resulting deflection increases.
