Castellated and common cruciform steel columns under axial and lateral cyclic loading
https://orcid.org/0000-0003-2532-5488
Abstract A numerical study has been done on the strength and hysteresis behavior of castellated and common cruciform steel columns under axial and lateral cyclic loading. The main feature of the castellation method is to make the I-sections stiffer by increasing the web height and reaching the higher moment capacity from the initial axis of the same weight of plain webbed members, and optimizing the use of heavy and costly constructional steel material and providing access to appropriate services. The effect of types of steel sections, web and flange boost of steel section, and length variations of specimens have been investigated and deformation, bearing capacity, hysteresis loops, ductility, and energy dissipation capacities have been discussed. Finite element analysis is performed based on initial geometric imperfection and geometric nonlinearity. The results of finite element analyses are close to the experimental results and showed that load carrying capacity of castellated cruciform steel columns was significantly higher and more suitable than common cruciform steel columns. Numerical results show that castellated cruciform steel columns have higher shear strength, good ductility and excellent energy dissipation capacity compared to conventional cruciform steel columns. The study evidenced that CPE steel sections can be used in seismic region. This study could provide a preliminary review for practical engineering applications and design specification for CPE steel sections.
