In a significant advancement for coastal infrastructure resilience, a recent study has assessed the vulnerability of school shelter buildings to seismic and tsunami threats, specifically focusing on the SDN 02 Sasak Ranah Pasisia elementary school in West Pasaman Regency, West Sumatera, Indonesia. The research, led by Fauzan from the Department of Civil Engineering at Andalas University, highlights the critical need for retrofitting existing structures to enhance their durability against natural disasters.
The shelter building, constructed in 2010 yet still incomplete, underwent a thorough structural assessment that revealed alarming deficiencies in its ability to withstand the working loads imposed by both seismic and tsunami forces. “Our findings indicate that several columns were inadequate for supporting the required loads, which is a serious concern for the safety of students and staff,” Fauzan stated. This revelation underscores the urgent need for intervention in buildings that serve as safe havens during emergencies.
To address these vulnerabilities, the research team designed a retrofitting solution using concrete jacketing, a method known for its effectiveness in reinforcing structural integrity. The study also developed fragility curves to evaluate the building’s performance before and after the retrofitting process. The results were promising: retrofitting reduced the probability of complete damage from earthquake loads by 18% at a peak ground acceleration (PGA) of 0.520 g, and similarly, it decreased the likelihood of tsunami damage by 20% at a wave height of 5.00 meters.
The implications of this research extend beyond academic interest; they resonate deeply within the construction sector. With natural disasters becoming increasingly frequent and severe, the demand for resilient infrastructure is surging. Contractors and builders can leverage these findings to advocate for retrofitting existing structures, ensuring compliance with updated safety standards and enhancing community safety. As Fauzan aptly noted, “Investing in retrofitting not only protects lives but also secures the future of our educational facilities, which are vital for community resilience.”
This research, published in the Journal of the Civil Engineering Forum, reinforces the importance of proactive measures in construction and urban planning, particularly in coastal areas prone to natural disasters. As the construction industry grapples with the dual challenges of aging infrastructure and climate change, studies like this one provide a roadmap for effective mitigation strategies, fostering a culture of safety and preparedness.
