The Central Coast of Vietnam has had a long history of severe typhoons and flooding. Efforts have been made to minimize the effects of these natural disasters on both people and properties. There are many approaches in minimizing the effects, including early warning and better evacuation plans, helping local residents prepare better for typhoons and living with them while a typhoon is going through an area, and building more resilient systems.
This project focuses on analyzing the effects of a Type 13 typhoon on a single-family house commonly found along the Central Coast of Vietnam. The design of the winner of ISET’s Resilient Housing Design Competition was selected to be constructed and analyzed in SAP2000 (version 15), a structural analysis software. The ASCE 7-05 Design Manual and particularly Chapter 6-Wind Loads were consulted in determining the wind pressure distribution on the house of a wind generated from a Type 13 typhoon.
After constructing the model in SAP2000 and running the analysis, several conclusions were drawn from the model. The dead load effects, including the dead weight and the gutter loads, dominated over the wind loads. This was not the expected results. The maximum deflection on the model occurred at the connection between the top of the lower roof and the bottom of the emergency access window. The maximum stress concentration occurred at the exterior horizontal girder at the back of the house (where the upper roof tips down).
