The apparatus is equipped with a set of columns made of different materials and dimensions, enabling evaluation of all parameters affecting column behavior. It includes suitable end pads to simulate various boundary conditions, such as simply supported, cantilever (fixed-free), and fixed-fixed configurations. High-quality linear bushings are used in the load transmission mechanism to minimize friction and ensure accurate application of axial load on the column. The applied force is measured by a 200 kgf load cell with an accuracy of 0.5% and displayed via a portable digital indicator (STI-50). The indicator supports bridge output configuration (mv/v) and allows adjustment of load cell parameters, including calibration, nominal capacity, and measurement accuracy.
