Experimental Study of the Stage-Discharge Relationship for an Upstream Inclined Grid with Longitudinal Bars

2013

AbstractIn this paper, the outflow process of an upstream inclined grid with longitudinal bars is studied by using the dimensional analysis and the incomplete self-similarity theory. Next, the theoretical analysis shows that a power equation can be used for establishing the stage-discharge equation. The coefficient and an exponent of the power equation depend on the slope angle and the void ratio. Finally, this new stage discharge is tested by using measurements obtained by laboratory runs conducted in this investigation.

The methods for the durability evaluation of pitched roof

2010

The research carried out by the Unit of Palermo, “Planning and experimental evaluation methodologies of discontinuous roofing class durability”, becomes part in the more general picture of evaluation and control of the technological quality of complex products for the building and in particular of durability, fundamental to reach the quality in building (ISO 8402, UNI 10838), cause it regards maintenance over time of the performances owned at the moment of the entrance in exercise and the modalities in which them decay during time. For the research result fundamentals the normative contributions, in international field of CIB W80/RILEM 175 (Service Life Methodologies) and ISO TC59-Buildings…
