Wind Loads in Low-Rise Buildings with Parapet: A Systematic Review

Abstract

A relevant analysis for the design of buildings is wind-induced loading. Although this has led to numerous studies, there have been relatively few investigations on the effects of parapets on wind loads. This systematic review addressed quantitative and qualitative behavior of wind loads in buildings with parapets in the Web of Science, ScienceDirect, SCOPUS, and Compendex databases. Using alternative methods such as citation searches and websites were selected 6 research articles were and added 6 papers. The results treat the influence of parapets on the behavior of the wind on roofs of low-rise buildings, especially wind loads, and its correlation with the building's geometric characteristics and parapets. The results identified pressure increases on roofs for low parapets (h<1.0 m); however, the dates vary according to the h/H ratio. Also, in general, the higher the parapets, the highest the reduction in the intensities of the pressure coefficients. Still, the porous and cantilevered parapets are more efficient and economically viable as a device to mitigate wind loads when compared to solid parapets in low buildings. Finally, for an open canopy, the height of the parapet is the main parameter, although the length of the building is also relevant.
