A groundbreaking study on the traditional Dhajji-Dewari structures has emerged from the University of Engineering and Technology (UET) Peshawar, shedding light on how numerical modeling can enhance the seismic resilience of these unique timber-braced masonry buildings. Led by R. Sheheryar, a Master’s student in Structural Engineering, the research offers a fresh perspective on optimizing bracing configurations to improve lateral strength while minimizing timber use.
Dhajji-Dewari structures are characterized by their distinctive construction using vertical and horizontal timber posts, diagonal bracings, and random rubble masonry, often seen in the earthquake-prone regions of Kashmir. Known for their impressive lateral deformability, these buildings have stood the test of time, but with the increasing frequency of seismic events, there is a pressing need to innovate and reinforce their design.
In the study, published in ‘Numerical Methods in Civil Engineering’, Sheheryar and his team developed a numerical model utilizing the finite element-based software SeismoStruct. This model evaluated the in-plane force-deformation capacity of Dhajji wall panels under various bracing configurations through static pushover analysis. “Our goal was to create a reliable numerical framework that not only reflects the actual behavior of these structures under seismic loads but also aids designers in making informed choices about bracing configurations,” Sheheryar explained.
The research findings indicate that by carefully selecting bracing configurations, structural engineers can significantly enhance the lateral strength and deformability of Dhajji walls. This optimization could lead to reduced timber consumption, translating into lower construction costs and a more sustainable building practice. “This approach could revolutionize how we think about traditional construction methods, making them more resilient and economically viable,” he added.
The implications of this research extend beyond academic interest; they have the potential to reshape construction practices in regions prone to earthquakes. By adopting these numerical modeling techniques, construction professionals can better prepare for seismic events, ensuring that buildings not only meet safety standards but also preserve the cultural heritage embodied in the Dhajji-Dewari design.
As the construction sector increasingly embraces technology and data-driven solutions, studies like this one pave the way for a future where traditional building methods are enhanced through modern engineering principles. The research from UET Peshawar could serve as a blueprint for similar initiatives across the globe, reinforcing the need for innovation in preserving architectural heritage while ensuring safety and sustainability.
