Concrete Filled Plastic Stub Columns Strength under Axial Compression

The development of Concrete Filled Plastic Tube (CFPT) Stub Columns, is commonly used in the areas where concrete structures interact with marine and saline environments, compared to regular columns. Several CFPT stub column samples were prepared investigate their behaviour under certain loading conditions. main objective this study was conduct an experimental investigation observe effect using different diameters on final strength In order achieve target, two types conditions applied, including separate load combined plastic tube simultaneously. revealed a significant improvement compressive columns (70 - 100 150 mm). Overall results show that use provides better mechanical performance ordinary An evaluation available calculation methods predict load-carrying capacities CFPT. suggested situations common may cause issues related its deterioration disintegration response severe weather
