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 ...

LCA comparison of roofing materials for flat roofs
Smart and Sustainable Built Environment, 2015Purpose– The environmental performance of several flat roof systems with different materials and insulation thicknesses is compared using life cycle assessment (LCA), with the aim to determine the roofing materials with the highest environmental performance.

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.

Maintenance programmes for flat roofs in existing buildings [PDF]
Property Management, 2017 Purpose The purpose of this paper is to propose a maintenance programme for flat roofs in existing buildings, based on the inspection of 26 buildings in-service conditions, located in the Lisbon region, in Portugal. A proactive maintenance of flat roofs

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

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.

Unstable Region in the Flat-Roof Resonator
Applied Optics, 1967Applicando il metodo numerico iterativo, già usato in un nostro precedente lavoro, abbiamo dimostrato che questo tipo di risonatore può avere regioni di instabilità dove sono presenti alte perdite. Applicando un metodo di perturbazioni successive, abbiamo dimostrato che esistono zone di inversione fra il modo fondamentale e il secondo modo pari.

A microwave or laser resonator with flat-roof mirrors is discussed from a theoretical point of view. When the angle of the roof is extremely small, on the order of 10−3 rad for microwaves or 10−3–10−6 rad for optics, this resonator has some features in common with the confocal resonator.
