Resiliency Assessment on the Structural Durability of Selected Concrete Buildings in Virac, Catanduanes

This study investigated the structural durability of selected public or government concrete buildings in Virac, Catanduanes. It examined the socio-economic profile of construction professionals, assessed the durability of different building types, evaluated rehabilitation measures, and analyzed structural damages. It used descriptive method to gather both quantitative and qualitative data. Primary data were collected through interviews and survey questionnaires. Descriptive statistics, including frequencies, percentages, ranks, and weighted means, were used to analyze the data. The study revealed that school and health facilities exhibited high durability having weighted means ranging from 3.60 to 3.87 (very durable) while other concrete buildings showed varying degrees of resilience with a mean rating of 3.33 (durable). Typhoons primarily affected non- structural elements like windows and roofs showing that these elements have weighted ratings of 4.70 and 4.03, and respectively indicating a descriptive rating of very severe damage while the structural elements, like walls, posts and beams, show slight damage with mean ratings ranging from 1.40 to 2.13. Rehabilitation measures, such as structural reinforcement with retrofitting and column jacketing, deemed most effective with mean ratings of 3.67 and 3.80, respectively. Key factors influencing building durability included construction quality, material quality, and environmental factors. The study emphasizes the importance of high-quality materials, disaster resilient design, and efficient construction practices to enhance building resilience against typhoons which can serve as basis in updating the NSCP to address the increasing intensity of typhoons as effect of climate change. Recommendations include improving construction quality by promoting the use of high-quality materials, strengthening building codes, promoting awareness on disaster resilience, and addressing project delays by streamlining bureaucratic processes, improving access to construction materials, and enhancing project coordination and communication.
