Special Issue Information

Dear Colleagues,

Construction materials play a critical role in building modern infrastructures, representing an enormous investment in raw materials, energy, and capital, with the result being significant environmental burdens and social costs. In recent decades, novel advanced construction materials and their structural applications have emerged with the support of continuously developing innovative technologies. To achieve higher-performing construction materials and advanced construction technologies, further research has drawn great attention from researchers and the interest of technicians.

After the success of the Special Issue of Materials on “Experimental Study, Numerical Simulation & Structural Applications of Construction Materials”, we are delighted to open this second edition.

This Special Issue of Materials invites original research articles and comprehensive reviews regarding experimental studies, numerical simulations, and structural applications of construction materials.

Abstract

High-strength steel (HSS) members with welded sections exhibit a notably lower residual compressive stress ratio compared with common mild steel (CMS) members. Despite this difference, current codes often generalize the findings from CMS members to HSS members, and the previous unified residual stress models are generally conservative. This study focuses on the membrane residual stress distribution in Q690 steel welded box sections. By leveraging experimental results, the influence of section sizes and welding parameters on membrane residual stress was delved into. A larger plate size correlates with a decrease in the residual compressive stress across the section, with a more pronounced reduction observed in adjacent plates. Additionally, augmenting the number of welding passes tends to diminish residual stresses across the section. Results showed that membrane residual stress adhered to the section’s self-equilibrium, while the self-equilibrium in the plates was not a uniform pattern. A reliable residual stress simulation method for Q690 steel welded box sections was established using a three-dimensional thermal–elastic–plastic finite element model (3DTEFEM) grounded in experimental data. This method served as the cornerstone for parameter analysis in this study and set the stage for subsequent research. As a result, an accurate unified residual stress model for Q690 steel welded box sections was derived. Full article
