In the quest to build more sustainable and cost-effective structures, a groundbreaking study has emerged from the Construction Engineering and Management Department at Pharos University in Alexandria, Egypt. Led by Momen M. Ali, this research could revolutionize the way large halls are constructed, particularly in the energy sector, where expansive spaces are often required for facilities like power plants, warehouses, and manufacturing units.
The study, published in the journal ‘Academia Materials Science’ (which translates to ‘Academia of Materials Science’), focuses on optimizing the design of reinforced concrete portal frames. These frames are crucial for supporting large, open spaces, and their design can significantly impact the overall cost and environmental footprint of a project.
Ali and his team investigated various configurations of portal frames, aiming to identify the most efficient design that minimizes material use and reduces bending moments under load. “The goal was to find a structural system that not only saves on materials but also reduces the carbon footprint,” Ali explained. “By doing so, we can contribute to a more sustainable construction industry.”
The researchers used advanced 2D finite element simulations with SAP2000 software to model different portal frame configurations. They tested frames with spans of 12 meters, 20 meters, and 28 meters, incorporating internal struts, broken girders, and horizontal ties. After analyzing 51 case studies, they found that a portal frame featuring a broken girder with a horizontal tie was the most economical.
The results are impressive. For a 12-meter span, this design could reduce material usage by 33%, leading to substantial cost savings. Even for larger spans of 28 meters, the savings, though slightly less, still amount to a significant 23%. “This approach can lead to a more sustainable and cost-effective construction process,” Ali noted. “It’s a win-win for both the environment and the economy.”
The implications of this research are far-reaching, especially for the energy sector. Large halls are a staple in energy infrastructure, from power generation plants to renewable energy facilities. By adopting this optimized portal frame design, energy companies can reduce their construction costs and environmental impact, aligning with global sustainability goals.
Moreover, this study opens the door for further innovations in construction technology. As Ali suggests, “The findings can inspire more research into optimizing other structural elements and materials, leading to even more efficient and sustainable construction practices.”
The construction industry is on the cusp of a significant shift, driven by the need for sustainability and cost-effectiveness. This research from Pharos University is a testament to how innovative thinking and advanced technology can pave the way for a greener, more efficient future. As the energy sector continues to evolve, such advancements will be crucial in building the infrastructure of tomorrow.
