Numerical investigation the influence of solid and porous parapets on wind loads on low-rise buildings.

Resumo

Several studies have shown that parapets mitigate the damage and economic losses due to wind action on buildings. Therefore, in this work, a computational analysis of the influence of different parapet geometries and heights on the wind flow on the roofs of low-rise buildings has been developed using the Ansys Workbench software. Solid and porous parapets were considered, and a decrease in the external pressure coefficient was observed as the height of the parapet increased, as well as a greater efficiency of porous parapets than solid ones.
