ABSTRACT
Evolving climate conditions continue to intensify typhoon winds, whose threats and damage to civil structures usually result in heavy economic losses and casualties. Despite this, most low-rise structures continue to receive less inadequate considerations on lateral forces; hence, failure still occurs on these buildings during typhoons, and most of the damages are attributed to the phenomenon named vortex shedding. As low-rise buildings comprise the largest class of vulnerable structures, they likewise need to be adequately designed to resist wind forces as induced by vortex shedding. Hence, this study aims to analyze and develop a typhoon-resistant low-rise structural model, which will be tapered to reduce across-wind responses, through Computational Fluid Dynamics (CFD) Simulation. Po-Lite panels were considered in creating initial low-rise models, whose vortex shedding, and natural frequencies have then been identified through CFD using SimScale software and Finite Element Analysis (FEA) using MSC Patran and Nastran, respectively. The CFD simulation results indicate that the Circular Tapered Model showed the lowest mean lift and drag coefficients and lowest vortex shedding frequencies for each meter height interval as compared with other models. Similarly, Modal Analysis in FEA yielded values on the models' natural frequencies and modal shapes, and only the Circular Tapered Model showed no coinciding vortex shedding and natural frequencies, indicating that no structural collapse occurs during the simulated typhoon winds. As a result, the study considers this geometry to be the governing low-rise Po-Lite model that can resist and adapt to the increasing intensities of typhoon wind loads. To better address other limitations, the study recommends that future studies employ wind tunnel tests, investigate medium- and high-rise structures, and apply different wind loading conditions, and consider the surrounding buildings in the analysis.
