🌟 Exciting Project Update! 🌟 I'm thrilled to share insights from our recent study on shear walls with staggered openings. These walls play a crucial role in resisting lateral loads during dynamic events like earthquakes and windstorms, helping to minimize structural damage and maintain the integrity of buildings. Our analysis utilized four verification models based on both characteristic and design values in accordance with Eurocode 1992-1-1. We employed two advanced methods: the Compatible Stress Field Method (CSFM) and the Drucker-Prager Plasticity Model (DPPM). 🔍 Key Highlights: CSFM: Focused on maximum principal concrete stress and reinforcement stresses, considering tension stiffening effects but neglecting concrete tensile strength. DPPM: Evaluated internal friction, tensile and compressive strengths, and post-critical behavior through damage parameters. Both methods used detailed numerical models with unique approaches to loading and constraints. This comprehensive study involved scaled-down models with precise geometric and material specifications, tailored assumptions for each method. Special thanks to our incredible team for their dedication and expertise. Your hard work made this in-depth analysis possible. Looking forward to exploring the practical applications of these findings and continuing to push the boundaries of structural engineering! #StructuralEngineering #ShearWalls #EarthquakeSafety #Innovation #Research #EngineeringExcellence #IDEAStatiCa #ABAQUS #

Reinforced concrete is one of the preferred methods of bridge construction worldwide, safely transporting millions of people each day. Behind the scenes, engineers are exploring new technologies to more accurately inspect these vital structures and ensure their continued structural integrity. Recently, 3D radar imaging has proven to be a promising tool that effectively identifies defects, even underneath the steel mesh cores of reinforced concrete.

💡PolyColumn Handles Second-Order Effects!💡 Second-order effects are the additional forces and deformations that occur when a structure displaces under load, impacting overall stability. ⚖️ Why does this matter? These effects can significantly influence the safety and reliability of your structures. 🛠️ PolyColumn includes second-order effects in its calculations, providing accurate and reliable results for your structural designs in line with Eurocode standards. ✅ #PolyColumn #Engineering #StructuralDesign #Eurocode #Innovation #Safety

Development of codes and standards for the structural analysis of ultra-high performance fibre reinforced concrete (UHPFRC) elements is still at infant stage because its use is still limited to few developed countries; and it’s hard at the moment to accurately design UHPFRC beam containing coarse aggregate (UHPFRC-CA) against shear loading. To contribute in solving this structural problem, an equation was developed in this paper for use in designing/predicting the shear capacity of UHPFRC-CA/UHPFRC beam.

📣📣Publication Alert: I am thrilled to publish a theoretical study (analytical model) that is able to track the entire nonlinear flexural behaviour of deficient multi-span structures and strengthened using externally-bonded strengthening techniques up to failure. The model has a potential capacity to determine the failure mode, the location of plastic hinge, the rotational capacity/curvature, moment redistribution ratio between the critical sections, and the load carrying capacity of the structure in question among others. Most importantly, the calculation of the mid-span deflection considering the external strengthening (ex: FRCM or FRP) is advantageous in this model, the matter that is often overlooked in the national and international standards. I would like to thank Dr. Ahmed El Refai, Ph.D., P.Eng. for such great and fruitful collaboration. Do not hesitate to contact me, should you have further question/discussion. The article link:

The Tenth International Conference on Steel and Aluminium Structures (ICSAS24) was held in Rio de Janeiro, Brazil, from June 5-7, 2024. Our Chair was represented by Anna-Lena Bours and Professor Markus Knobloch. Anna-Lena Bours presented her paper entitled "STABILITY VERIFICATION OF TWO-SPAN STEEL CHANNEL MEMBERS". Full paper will be available soon at https://lnkd.in/gRQqp3xt #Abstract: The competitiveness of steel structures in structural engineering is supported by the use of slender members, which, however, require a stability verification. Currently, worldwide research concentrates on single-span members with doubly symmetric cross-sections. Only a few design rules exist for mono-symmetric sections, like channels. Further, the normative verification models do not entirely exploit the potential of structural systems in engineering practice. Therefore, this paper provides experimental, numerical, and analytical studies on the stability behavior of two-span members with steel channels under combined loading. Five-point bending tests were conducted to analyze the lateral torsional buckling behavior and the influence of various parameters. A comprehensive numerical simulation model, validated with the experimental results, was used to define requirements for the design of two-span channel members at central support to assume ideal fork conditions. Based on a comparative study, an extension of the scope of the stability verification of EN 1993-1-1:2022 Annex C.2 is proposed, including modified design rules for two-span channel members to improve consistency and efficiency. #steelstructures #steel #girder #verification #buckling #civilengineering #analysis #channelsection #structuralengineering #research
