Özet

In practice, deflection problems are commonly encountered in beams and slabs. These deflections can prevent the operation of sensitive machinery or lead to a decrease in the stiffness of the section due to cracking. If deflection reaches excessive levels, cracks can propagate to larger extents, significantly reducing the load-bearing capacities of the elements. This study aims to explain the basic principles of total deflection calculations prescribed in TS500 and EUROCODE2. It uses four scenarios of various parameters to understand the methodological differences between the regulations and compare their results.

The effect of changes in various parameters on the selected simple beam was investigated. These parameters include the span length of the beam, ratios of tensile reinforcement, ratios of compression reinforcement and different concrete classes. The influence of each parameter's variation on the magnitude of short-term and long-term deflections according to TS500 and EUROCODE2 standards was investigated. These calculations were carried out based on the fundamental principles specified in both regulations, and the results obtained were compared.
