Subject: End-effect loads Добрый вечер! Как вы думаете, как следует перевестиEnd-effect loads ? (тема Supporting structures). Нагрузки концевых эффектов? нагрузки влияния концов? |
| perevod2009per, а Вы можете дать полное предложение? |
| эффект концевой нагрузки. |

If owing to the circumstances of the terrain or for economic reasons it is not possible to secure an entire natural terrain unit, the unprotected flank should be heavily tapered back in the downward direction. This is to ensure that the lower structures are not damaged by avalanches descending immediately adjacent to the defense structure. To hinder adjacent snow slab avalanches from spreading into the defense zone, additional structures may be placed at the edge of the zone. These should be positioned in the gap between the normal structures (distance L) and have a total length of at least 2 DK Separation walls arranged in the line of slope at the side of the structure should have a vertical height of approx. HK/2 to prevent full-depth avalanches spreading to the structure. They substantially reduce the end-effect loads as shown in Section 45. Also, to prevent damage to the supports, the separation walls should be extended down to the downslope foundations или End-effect loads With finite width of the supporting surface in the contour line, incremental end-effect loads occur by virtue of the fact that the snow can flow laterally around the surface, so that a lateral restraining effect occurs. The end-effect loads are dependent not only on the factors determining the snow pressure on an infinitely wide surface, but also on the dimensions, shape and surface roughness of the grate, and even more so on the glide factor. The basic snow pressure distribution is shown in Fig. 17. For practical calculations, the end-effect force is substituted by an equivalent, constant, force per meter run S'R acting over the length Д1 (see Section 5.5.2.4). |
