I'm excited to share that our latest work, titled "Aeolian Sand Challenges in Desert Rail Infrastructures, Overview of Iran’s Experience and Advancement," has been published in the #Journal_of_Construction_and_Building_Materials. This research explores the primary challenges faced by railways in the deserts of Iran, including how they affect civil works, track superstructure, rolling stock, and signaling systems at both ultimate and serviceability limit states. We also examine the measures implemented in Iran to mitigate these challenges based on the source, transport, or deposition areas of sand dunes. Additionally, we classify the performance of Iran's desert railways based on wind sand activities and have created a distribution map of sand accumulation in the main desert lines.

In order to reduce costs in the top-down method and solve the problem of fabricating integrated diaphragm walls in urban areas and for small projects, an innovative approach has been used by #Iranian engineers that eliminates the integrated diaphragm wall and top-down construction with the use of a sequential peripheral wall (SPW). The SPW approach uses peripheral columns instead of peripheral walls. The link to our newly published paper entitled “Innovative Top‑Down Construction Method with a Sequential Peripheral Wall” by presenting a case study is given below for those who are interested in this subject: Expressing sincere gratitude to #Dr. Mahdi Rojhani for his cooperation.

I am pleased that my article reached 600 reads in ResearchGate. Achieved on January 21, 2023 Article: Hollow Reinforced Concrete Bridge Column Systems with Reinforcement Details for Material Quantity Reduction: I. Development and Verification January 2014, Journal of the Earthquake Engineering Society of Korea 18(1) DOI: 10.5000/EESK.2014.18.1.001 Abstract: The purpose of this study was to investigate the performance of hollow reinforced concrete bridge column systems with reinforcement details for material quantity reduction. The proposed reinforcement details have economic feasibility and rationality and make construction periods shorter. A model of hollow reinforced concrete bridge columns was tested under a constant axial load and a quasi-static cyclically reversed horizontal load. As a result, proposed reinforcement details for material quantity reduction were equal to existing reinforcement details in terms of required performance. The companion paper presents the experimental and analytical study for the performance assessment of hollow reinforced concrete bridge column systems with reinforcement details for material quantity reduction. https://lnkd.in/gXNG2bsS

Application of CFRP strips to concrete beams as strengthening in shear.

One of the fascinating activities of my life was conducting geotechnical shaking table test (on my M.Sc thesis) at the Physical Modeling and Centrifuge Laboratory at the School of Civil Engineering, College of Engineering, University of Tehran to validate the #seismic response of the optimized-design numerical #GRS wall model with modular-concrete block facing. This shaking table was 1.2-m wide and 1.8-m long, with one freedom degree. The model holder, screwed onto the table, was 0.8-m wide, 1.82-m long, and 1.23-m high. It was made of rigid transparent plexiglass sheets to observe the wall behavior and deformations. To do this, a fully-equipped reduced-scale model of the #GRS_MB wall was built on #Firuzkoh sand. In addition, scaling rules and #soil_spatial_variation were considered for this model. Moreover, the #ground_motions_data derived from #Iran_Iraq time-series history was applied to the model. If you would like to gain more insight on this field, refer to the following publications: https://lnkd.in/eGbVR_cw "Shaking table test on a geosynthetic reinforced soil modular block wall based on response surface method for reliability analysis" Authors: RA Nazari, S Jalili, H Sharafi, H Jafari Journal: Arabian Journal of Geosciences 15 (23), 1703

My paper, "Seismic Performance of Masonry-Infilled RC Frames and Its Implications in Design Approach: A Review", published in the journal “Practice Periodical on Structural Design and Construction” explores behaviour of RC frames with or without masonry walls and also critically discusses the implication of the consideration of masonry walls on the design of RC frames. This work has important implications for structural design. Check out the full paper here: https://lnkd.in/ef8fQRFM. #research #published

Happy to share that our paper on "Design of Slender Built-Up Back-to-Back CFS Channel Columns with Pinned Warping-Free Ends" is now published in Journal of Structural Engineering. https://lnkd.in/gz_TFNYq. This is the next research study that I and Prof Mahen Mahendran conducted on the applications of built-up cold-formed steel channel members and solutions for related questions from CFS building engineers in Australia. Other papers on this topic can be found here: https://lnkd.in/g5-guFFV Highlights · Investigated the behaviour of built-up back-to-back channel (BC) compression members with pinned warping-free ends. · Torsional and flexural-torsional buckling modes are not critical. · The capacity of BC compression members could be significantly higher than twice that of their individual members. · Arrangement and characteristics of screw connections could have considerable effects. · BC members with pinned warping-free ends have lower compression capacities than those with pinned warping-fixed ends. · Proposed a reliable DSM based design method and recommendations.

Dr Jawed Qureshi presents detailed worked examples on the design of doubly reinforced concrete beams according to Eurocode 2. This video is a vital addition to the Eurocode 2 Concrete Design lecture series and includes two comprehensive tutorial examples. Designing doubly reinforced concrete beams involves adding steel reinforcement on both the tension and compression sides to handle higher loads. The process begins with determining the loads the beam will support, followed by selecting initial beam dimensions. Next, calculate the required areas of tension and compression steel using bending moment formulas and Eurocode 2 concrete design standards. Ensure the concrete and steel stresses are within permissible limits to maintain safety. Finally, detail the reinforcement with proper spacing and anchorage. This design approach enhances the beam's capacity and ensures structural safety and efficiency under significant loads. 📚 Whether you're an engineering student or a seasoned professional, this video is packed with valuable insights and practical knowledge that will enhance your understanding and skills in concrete design. 🔗 Watch the full video here: https://lnkd.in/eXVetQs2 I am passionate about sharing knowledge, adding value, and making an impact through education. My goal is to empower engineers, promote inclusion, diversity, and social mobility, and prepare the next generation for Industry 5.0.

I am happy to share our latest review paper published on "Engineering Structures". Dowel action is one of the shear transfer mechanisms(STM) in reinforced concrete. Our recently published paper uses the Beam on Elastic Foundation(BEF) theory and concrete fracture mechanics to analytically model the dowel splitting process. This work can provide new insights into the role of dowel action in the shear failure of reinforced members without shear reinforcement. I'd like to thank my copromotor Prof. Yuguang Yang and my promotor Prof. Max Hendriks. This work cannot be done without their guidance and support. The paper can be found at the following link: https://lnkd.in/eAwfgh8X

I'm pleased to share the recent publication of our research paper in "Structural Concrete" journal by fib ��� International Federation for Structural Concrete – Fédération Internationale du Béton, entitled "A Holistic Life Cycle Design Approach to Enhance the Sustainability of Concrete Structures." This paper, written in the framework of SmartincsEU project, was co-authored together with Liberato Ferrara, Matteo Parpanesi (DICA department, Politecnico di Milano), and Nele De Belie (Universiteit Gent). Our work represents a pioneering effort, marking a significant advancement in the integration of sustainability analyses, specifically Life Cycle Assessment (LCA) and Life Cycle Costing (LCC), with Durability Assessment-based Design (DAD) for innovative cementitious materials. Such an innovative approach reshapes the way we conceptualize sustainable structural design. The case study of a basin made with Ultra High Performance Concrete (UHPC), containing geothermal water and subjected to XS2 and XA3 exposure classes has been investigated for the specific purpose.
