“During the poster session, I had the opportunity to present my research on integrating remote sensing, deep learning, and restoration models for post-disaster damage assessment and recovery predictions following tornado events. The main findings demonstrated that by utilizing these advanced technologies, large-scale damage maps can be generated rapidly and accurately. This approach improves recovery time estimates and supports more efficient resource allocation in post-disaster scenarios. I chose this topic because of its potential to enhance community resilience and emergency response efforts. Several attendees expressed interest in the details of data processing and the training of machine learning models, as well as the practical applications of my methodology and its potential expansion to other domains. My advice for students preparing for their poster sessions is to focus on clearly communicating the key contributions of your research and to remain open to new perspectives from the audience.” – Abdullah Braik, Graduate Assistant – Research (CVEN) PI: Dr. Maria Koliou

 

“My research is about conducting community resilience analysis under natural hazards using an agent-based modeling approach. As all the entities involved in the community recovery process are generated in the agent-based model, with their characteristics and behavior clearly defined, the recovery process can be simulated in a detailed manner. The greatest challenges I face during my research is how to code the program to achieve the agent-based simulation. I took some Python lessons and attended Python tutorial lectures online. Through many rounds of trials and errors, I was able to make my Python code run. Another takeaway from doing my research is how to use the powerful HPRC platform at Texas A&M to save computation time to a great extent. In the future I would like to use the agent-based modeling approach on a wide variety of testbeds associated with a wide spectrum of natural hazards.” – “Xu Han, Postdoctoral Researcher (CVEN) PI: Dr. Maria Koliou

 

“Presenting at the 2024 CIR Poster Session provided me an invaluable opportunity to speak with my fellow researchers and other industry professionals about how I can ensure that my research has both intellectual and practical merit to civil engineering. I strongly believe that while developing more advanced methods to model and design civil engineering projects is important, as researchers we cannot afford to lose sight of the practical effects and applications that our research will have on the field. My research involves testing full-scale bridge supports for TxDOT to examine how current detailing practices can be improved while simultaneously improving constructability, which poses a challenge in finding an appropriate balance between the theoretical and the practical nuances. My experiences during the poster session gave me a great deal to think about moving forward in my research about how I can model these complex processes while also generalizing my conclusions so that the average engineer can understand and implement my improvements. I strongly encourage my fellow students to be bold in their ideas and to take the opportunity to share them at these poster sessions because oftentimes our best ideas are inspired by the thoughts of others.” – Joshua Henson, Graduate Assistant (CVEN) PI: Dr. Kinsey Skillen

 

“Our research funded by the Texas Department of Transportation on re-examining minimum shear reinforcement requirements in prestressed concrete girders identified that current design provisions may not fully address girder performance under low shear reinforcement conditions, with significant implications for structural integrity and shear failure prevention. Feedback from CAP Board members emphasized the value of the two methodologies we developed, particularly the simplified approach, which was praised for its practicality and ease of implementation in updating design codes. Inspired by the aging bridges in the U.S. and the growing demand for safer prestressed concrete bridges to replace them, we overcame challenges such as designing large-scale tests and resolving conflicting design provisions through a mechanics-based approach. The High-bay Lab at the Center for Infrastructure Renewal supported large-scale experimental tests, offering advanced facilities for simulating shear conditions in prestressed concrete girders. This enabled accurate analysis and validation of our revised shear reinforcement guidelines. This research offers a pathway for updating shear reinforcement guidelines that better balance safety and efficiency, and it has allowed me to sharpen skills in experimental design, computational modeling, and project management. Moving forward, the plan is to finalize these findings and engage in discussions with TxDOT regarding the application of these provisions in real-world projects. For students preparing for their first poster session, I recommend confidently presenting the practical implications of their work while ensuring that key findings are explained clearly and concisely to make the greatest impact.” – Nikhil Potnuru, Graduate Assistant (CVEN) PI: Dr. Petros Sideris

 

“At the recent advisory meeting, I presented my research on “Enhancing Performance-Driven Mix Design: A Comprehensive Tool for Durability Assessment of Bridge Deck High-Performance Concrete Mixtures.” The feedback was highly encouraging, with attendees taking the time to explore the nuances of the work, asking insightful questions, and recognizing the value it brings to advancing performance-driven mix design. Our research addresses the need to shift from prescriptive to performance-based concrete mix design that optimizes mixtures’ selection to meet the durability/ service life performance for its application and exposure conditions. Our research led to the development of the “TxDOT Tool” – a simplified, user-friendly Excel-based Tool (spreadsheet) for DOT practitioners and contractors to conduct rapid & comprehensive durability-based performance evaluation of cast-in-place High-Performance Concrete (HPC) bridge deck mixes. Moving forward, we aim to extend the Tool’s application to other concrete applications (e.g., pavements, etc.) and incorporate a wide range of SCMs (e.g., natural pozzolans, waste glass, etc.) rapidly emerging in the construction industry. For first-time poster presenters, on three key aspects: the research topic, key findings, and why it matters. Use engaging visuals (and less text) to create a compelling narrative that engages the audience.” – Pravin Saraswatula (TTI) PI: Dr. Anol Mukhopadhyay

CIR Welcomes CyBe RC 3D Printer: Modernizing the Development of Sustainable & Resilient Construction Methods

by

Last year, the Center for Infrastructure Renewal (CIR) welcomed the arrival of the CyBe RC (Robot Crawler) 3D printer. Thanks to its robotic arm and “crawling” mechanism, the CyBe RC can move freely, unlike more stationary 3D printers currently on the market, and is capable of printing entire houses. Due to its extended range of motion and ease of maneuvering, the CyBe RC can print both vertically and at an angle while navigating different locations within the building plan.

Dr. Petros Sideris, from the Texas A&M University (TAMU) Civil Engineering department, leads the research conducted with the CyBe RC. His research group focuses on constructing buildings using 3D printing methods and assessing how these structures perform under various climates, conditions, and natural disasters. Dr. Sideris explains, “We explore the development of new structural systems that can withstand gravity, wind, and earthquake loads, leveraging the capabilities and limitations of this technology. Alongside these systems, we develop novel design methodologies, which we validate through computer models and material testing on a larger scale.”

The group’s structural designs emphasize integrating resilience and sustainability while minimizing the construction’s carbon footprint. One approach involves using natural materials as the printing medium, replacing less sustainable materials that have a higher carbon impact. Hempcrete, studied by Dr. Sideris’ research team, serves as an eco-friendlier option that still performs well under environmental conditions, similar to traditional concrete.

The primary objective of their work is to facilitate widespread adoption of construction 3D printing by developing design methodologies and computational tools. Essentially, they aim to create a blueprint for this innovative construction method. Additionally, they hope to address the national demand for affordable housing, especially during the ongoing housing crisis, and apply these methodologies to various construction projects, including bridges, buildings, and other infrastructure.

Collaborating with other Texas A&M University colleagues, such as Dr. Anand Puppala, Dr. Zachary Grasley, Dr. Maria Koliou, Dr. Manish Dixit, Dr. Wei Yan, and Dr. Jeffrey Bullard, these research efforts have attracted sponsorship from the U.S. Department of Housing and Urban Development  (HUD), U.S. Department of Energy (DOE), U.S. Department of Education (DOEd), and the U.S. Army Corps of Engineers (USACE). Their combined efforts contribute to advancing sustainable and resilient construction practices.
