In 2019 alone, Temerloh district located in central Peninsular Malaysia has been hit by unpredictable wind storms in localised areas which damaged more than 185 rural homes. This research set out to assess the structural vulnerabilities of damaged rural houses to severe winds in Temerloh and lessons learned from windstorm damage through field surveys of damaged homes between March 2019-August 2019 and supplemented by district-level post-windstorm reconnaissance reports prepared by Malaysia Civil Defense Force (APM) and other information gathered from local government. Results indicate poor performance of structural and non-structural building components in resisting high wind loads due to inadequate design, under-strength of failed building materials and defective construction details. The results of this study could have important implications for government agencies, NGOs, builders, and engineers in assisting rural communities in reconstructing windproof resistant homes and planning for future windstorm risk management efforts specially catered to homeowners in Temerloh.Keywords: Rural housing; Windstorm; Resilience; Malaysia eISSN: 2398-4287 © 2019.

Internal flow induced acoustics is commonly noticed in corrugated pipes that provide both flexibility and strength in offshore flexible riser system. This phenomenon is commonly known as whistling when flow passes through the corrugated pipe at high pressure and high velocity. This paper evaluates the effect of corrugated pipe bending on the whistling behavior using 2D numerical simulation. It is found that the bending angle will have an effect on the peak-whistling Strouhal number (Sr p-w ). By incorporating the bending effect = 360 360 − in characteristic dimension, such that ( + ) rather than (W + r up ) which was proposed in literature resulted in smaller variation of Strouhal Number, Sr p-w . Hence, provide more accurate prediction of the phenomena and further enhance the practicality of the modified characteristics length in predicting the peak whistling Strouhal Number.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
