ANALISIS KINERJA KOLOM HOLLOW PRATEGANG BETON NANO SILIKA DENGAN KOMBINASI BEBAN SIKLIK DAN AKSIAL

Hollow columns offer material efficiency and mass reduction, which are crucial factors for the seismic resistance of bridge infrastructure in Indonesia. This study evaluates the performance of prestressed hollow columns based on nano-silica concrete under cyclic loading through finite element method simulation using ANSYS software. Secondary data were used to model variations in tendon diameter for specimens NS-1 (17.8 mm), NS-2 (15.2 mm), and NS-3 (14.3 mm). Simulation results show that the NS-1 model has the highest maximum lateral capacity of 376,283 kN (compression) and -386,247 kN (tension). Although NS-3 produced the greatest energy dissipation of 21,437,668 kN·mm, NS-1 generally outperformed in lateral strength and initial stiffness. All three specimens met the high ductility demand category with ductility values above 4. It can be concluded that an increase in tendon diameter directly contributes to the structure’s capacity to resist lateral loads. The use of nano-silica concrete with a compressive strength of 45.23 MPa, achieving a maximum drift ratio of 5%, demonstrates the material’s significant potential as a robust structural element solution for complex seismic loads.
