Evaluation of the Effect of Sheet Thickness on Reinforcement of Floors with Steel Sheet in Timber Structures Using Modal and Static Analysis

Abstract

Steel sheet applications, which are widely used in the reinforcement of timber floors encountered in rural and historical buildings today, may reduce the rigidity of the structure and may cause structural instabilities when applied unconsciously. This study systematically evaluates the effects of the change in steel sheet thickness on the timber floor behavior through modal analysis and static deflection studies. Eight different steel sheet thickness scenarios ranging from 0.1 mm to 20 mm were analyzed on the finite element model created using SAP2000 software. The first mode period value, mode shape and maximum deflection amount were evaluated for each model and the effects on the structural rigidity were compared. The findings showed that thin sheets such as 0.1 mm reduce rigidity and cause torsional mode; while the deflection values increase significantly due to the added mass at thicknesses of 5 mm and above and negatively affect the structural performance. The most efficient sheet thickness was determined between 0.2 mm and 0.5 mm both dynamically and statically. As a result of the study, it was revealed that the understanding of “the thicker the sheet, the stronger the structure” seen in unconscious timber floor reinforcements is invalid. It is emphasized that optimum sheet thickness should be determined based on engineering data in steel sheet reinforcement applications in timber structures. These findings reveal the importance of engineering-based reinforcement approaches in making traditional structures safer and more durable.
