PERILAKU KOLOM HOLLOW PRATEGANG BETON GEOPOLIMER DENGAN KOMBINASI BEBAN SIKLIK DAN AKSIAL

---

Indonesia is located in a region with high seismic activity; therefore, earthquake-resistant structures are strongly recommended. This study evaluates the behavior of prestressed hollow columns made of geopolymer concrete under combined cyclic and axial loading through finite element method simulations using ANSYS software. The study utilizes secondary data in the form of geopolymer concrete material properties with a compressive strength of 22.85 MPa and variations in prestressing tendon diameters of 17.8 mm (GC-1), 15.2 mm (GC-2), and 14.3 mm (GC-3). The simulation results indicate that model GC-1 exhibits the highest maximum lateral capacity of 269.675 kN (push) and -277.740 kN (pull). Model GC-1 also shows the highest stiffness and energy dissipation compared to the other models, with stiffness reaching 6.04 kN/mm and cumulative energy dissipation of 7189.418 kN·mm. However, GC-1 demonstrates the most brittle behavior, with a ductility value of 5.095. It can be concluded that increasing the diameter of prestressing tendons generally improves the column’s performance in resisting lateral loads, but results in a reduction in ductility. The use of geopolymer concrete with a compressive strength of 22.85 MPa can achieve a maximum drift ratio of 5%, indicating its strong potential as a durable and environmentally friendly structural material for seismic applications.
