ANALISIS STRUKTUR KOLOM PADA GEDUNG PARKIR RUMAH SAKIT DI SEMARANG

The parking building of Hospital Semarang is a space frame system that is assumed to be on soft soil (SE) and analyzed based on the Special Moment Reinforced Concrete Frame System (SRPMK). With quality concrete, fy=25 MPa, reinforcing steel quality, fy=420 MPa, and reinforcing steel quality, fy=280 MPa. Load analysis refers to SNI 1726 – 2019, and concrete regulations refer to SNI 2847 – 2019. Based on the results of the dynamic response analysis obtained from the program ETABS v19.1.0 follows the requirements of the variety of motion, with mode 1 showing the direction of translational motion X direction, which is 49,9%, mode 2 shows the translational movement in the Y direction which is 71.24%. Mode 3 shows the movement of the structure in the rotation, which is 57.72%. Dynamic base shear,  2393,984 kN, and  2743 4332 kN have met the requirements, reaching 100%. The earthquake direction applied was in the orthogonal direction with a redundancy factor value (ρ) of 1.3. There is no deviation between levels that exceed the allowable limit. P-Delta checking of the structure concluded that the structure remains stable. The results of the analysis of the cross-sectional capacity of the column obtained from the spColumn v6.00 program can be concluded that for a column with dimensions of 600x800, it is not strong enough to withstand the working load, because the minimum load is within the design strength of the interaction diagram. The maximum load is outside the strength of the interaction diagram plan. While the column with dimensions of 600x600 is still vital to withstand the working load because the minimum and maximum loads are in the strong interaction diagram plan.
