D1/D2 SINGLE-SIZED AGGREGATE DEAD LOAD

D1/D2 SINGLE-SIZED AGGREGATE

Granulat l mentaire D1/D2

Building Materials

A grain that passes fully through the sieve D2 and that is fully retained by the sieve D1; this definition is purely theoretical ( D1 and D2 being two successive main dimensions in the standardized table).

Hydraulic Work; Civil Engineering Structure

1. A barrage built to cut off partly the current of a river.

2. Cutoff (cofferdam, sluice, etc.) built on a waterway to stop the flow and temporarily divert the water in order to do construction on dry land.

3. A barrage built through a river to low rate of flow in order to raise the level upstream from a certain distance.

4. Syn. with BARRAGE; WEIR

Syn. with STORAGE RESERVOIR

DAMAGE Endommagement

Strength of Materials

A phenomenon of fatigue and progressive degradation that impairs a structure (or a test specimen) subjected to a variable loading in the course of time and especially, to a cyclic change (periodical). This structure is damaged before breaking. The definition of the injury (or damage) can be, physical and qualitative, or empirical and well defined. On the other hand, the injury of a piece not broken, but having undergone cycles of fatigue, reflects physical property variations of the material, such that it's state of cracking.
