“…Therefore, detecting and analyzing cracks are essential for structural safety [3]. One way to detect cracks is to use vibration-based methods, which measure how cracks affect the local stiffness, natural frequency, and mode shape of the structures [4]. Many researchers have used different models and methods to study cracks in the various structures.…”

Different solid materials are widely used in various constructions due to their availability and low cost. However, cracks or conversions in the structures can affect their stiffness and vibration signatures. This research aims to evaluate the load distribution, deformation, and the effects of the cracks on the natural frequencies and deformations of iron, steel, and titanium beams. A finite element-based model and COMSOL Multiphysics software were employed to measure and compare the frequencies and strengths of the beams. The results showed that the frequencies increased with the load, and titanium beams had the highest frequencies and deflections, while steel beams had the highest stress resistance. This frequency analysis can help to detect very small cracks (less than 0.05 mm) in the beams. The study concluded that steel is the most suitable material for construction due to its elasticity, availability, and low cost.

This research examines the behavior of Spiral Reinforcement Columns (SRCs), an innovative structural system consisting of concrete-filled steel tubes augmented with spiral springs, under diverse loading scenarios. Utilizing Finite Element Analysis (FEA), the study evaluates the impact of varying spiral spring diameters on the SRCs' performance. The findings reveal that springs with an 84 mm diameter significantly improve suspension efficiency over those with diameters of 64 mm and 80 mm. Springs with larger diameters demonstrate enhanced resistance to deformation, diminished bending, and lower stress levels. As a result, SRCs equipped with larger diameter springs exhibit superior stiffness, strength, ductility, and energy absorption capabilities compared to their counterparts with smaller diameters. The outcomes support the potential of SRCs with spiral springs as an effective seismic-resistant structural alternative.
