Ponding Effect on Flat Roofs

Structural Engineering International: Journal of the International Association for Bridge and Structural Engineering (IABSE), 2000
If a flat roof is relatively easily deformed, excessive accumulation of water on the roof can give rise to the ponding effect, whereby autoexcitation of the deformation occurs, possibly leading to collapse. This article examines the conditions under which the ordinary limits for deflections of roofs under variable loads are sufficient to withstand the ...

Convex Flat-Roof Resonator

Applied Optics, 1969
Lo studio del risonatore "flat-roof", tetto piatto, da noi estesamente sviluppato in precedenza è esteso al caso di "tetto" convesso, di interesse per le applicazioni. Con la procedura numerica iterativa ed usando anche un metodo perturbativo si sono valutati modi, phase shift e perdite, in un numero di casi.

Ventilated flat roofs: A simplified model to assess their hygrothermal behaviour [PDF]

open access: yesJournal of Building Engineering, 2019
The hygrothermal behaviour of the opaque building envelope (facades and roofs) is a topic worthy of investigation for the scientific community, especially in consideration of changes in construction techniques and lifestyle habits.

Pitched and Flat Roofs

1999
Both flat and pitched roofs can conveniently be subdivided into two main sections for purposes of measurement, that is, construction and coverings. The order of measurement of these two sections varies in practice, but on balance it is probably better to take the construction first since this follows the order of erection on the site.
