Author Biographies

His expertise encompasses a wide spectrum of innovative and sustainable construction materials, including fly ash concrete, rubberized concrete, hybrid fiber-reinforced systems, and ultra-high-strength lightweight hybrid composites. He has also explored unconventional materials such as egg-cell powered concrete, glass fiber composites, rice husk ash concrete, and the partial replacement of animal bone as coarse aggregates—demonstrating a commitment to circular economy principles and eco-efficient infrastructure solutions. His core research areas include Ultra-High-Performance Concrete (UHPC), Lightweight Concrete (LWC), Geopolymer Concrete (GPC), and Strain-Hardening Cementitious Composites (SHCC), including Engineered Cementitious Composites (ECC). Furthermore, he is actively engaged in pioneering applications such as cementitious-based batteries and supercapacitors, cold-formed steel structures, and green building systems. Mr. Behera’s work extends to modern construction techniques including 3D printing, prefabricated and modular systems, and rapid-deployment materials for disaster resilience. His interests also span the study of fire-resistant and insulating materials, corrosion-resistant alloys, self-healing concrete, phase-change materials, and nanomaterial-enhanced cementitious composites. Leveraging advanced characterization methods such as SEM, XRD, and non-destructive testing (NDT).

Mr. Aman Mola Worku Debre Berhan University, Debre Berhan, Ethiopia Email: amanmola512@gmail.com ORCID number 0000-0003-4802-7440 My name is Mr. Aman Mola Worku, lecturer at Debre Berhan University, civil engineering department. I obtained my Bachelor of Science in Civil Engineering from Debre Berhan University in 2017 and Master’s degrees in Civil Engineering (Structural) from the National Taiwan University of Science and Technology in 2021. My work focuses on advancing the understanding and predictive capabilities of how structures behave under extreme loading conditions, particularly seismic events. A significant highlight of my academic contributions is the publication titled “An improved first-mode-based pushover analytical procedure for assessing seismic performance of special moment resisting frame building structures,“ published in the Journal of Structural Engineering. This work proposes an improved analytical framework that refines first-mode-based approaches for evaluating the seismic demands on special steel moment frames, leading to more accurate and efficient performance assessments in engineering practice. Driven by a commitment to innovation in performance-based earthquake engineering, I continue to explore ways to improve design methodologies that account for complex nonlinear behaviors, supporting the development of safer and more sustainable structures.
