echanical characteristics of the column

[hhm1020]

Column is an integral part of building components. Housing construction in the cross-sectional dimensions of width and thickness smaller height relatively large blocks, called columns. Pillars supporting beams or plates, mainly under pressure, subjected to axial load. Sometimes also subjected to lateral loads. Such as floor and roof pillars, frame columns, column bent like. Sectional shape of fence split rail and picket a square pillar column, rectangular column, circular column, T-shaped column, I shaped column, L-shaped column, ten shaped column, two limbs column, a tubular column and the like. Column dimensions and mechanical characteristics of the column, and the supporting role of point of load conditions.

Under axial load, the material column section reaches ultimate compressive strength and damage, known as a short column. Material column section does not reach ultimate compression strength, buckling due time member (instability) and damage, called long column. Failure characteristics in between the two circles, known as the long column. Practical engineering reinforced concrete columns generally fall in long columns. Construction of the main building --- wall. In housing construction, the firm are larger width to height and size, and the relatively small thickness member, called the wall. The main wall to withstand strong parallel to the wall of the load. But also withstand the vertical wall or parallel to the wall of the horizontal load.

Such as load-bearing walls, shear walls, mixed walls, partition walls, etc. Sectional shape of the wall with a single material solid walls, hollow walls and a best composite decking brand variety of material combinations composite wall. In addition to the function of the wall structure to withstand the load and pass the foundation, but also serves as external wall insulation, insulation, water, noise, building envelope and other functions, also serves as interior partition, soundproofing purposes, and should have a moisture barrier, decorative features . Some partition walls made of activities, so that the flexible use of interior space.

Be still my denim-loving heart. While I've never been Nautilus-on-a-strap guy, there's no questioning that the casual-yet-elegant design of the Nautilus works well with the combo. The ref. 5980R was a secondary market darling, especially with the rose gold bracelet, the watch on a leather alligator strap still had a pretty high demand. I'll be curious how the market will react to a more casual version of the watch. https://is.gd/FZMh0w
