6.22), the deck plate, deck beam and truss upper (lower) chord are replaced by a continuously welded plate/beam system. The plate carries the direct loads along its span while it functions as top flange of the deck beam and the main girder system. Two-way deck-covering designs generally ...
Joist and beam cantilevers must not exceed ¼ the length of the joist or beam span. Joists must not exceed the below lengths based on its dimensions, joist spacing, and design plan (with or without cantilevers). Guidelines are for southern pine lumber projects. Deck Joist Spacing Joist Spa...
span pier of the trestle; double station steel is arranged at the top of the spiral welded pipe and is used as a trestle distributive girder; an open groove for limiting the trestle distributive girder from becoming a main member is formed in the spiral welded pipe; the bailey beam is ...

Most GoM platform rigs supplied by drilling contractors would have 40 ft skid beam spacing. Use of cantilevers to gain additional deck space is also commonplace. Most efficient cantilevers are achieved when these are about one half the lengths of the deck spans. Therefore, 80 ft by 80 ft ...
(not Home depot or Lowes) will also carry 14’ and even 18’ and 20’ lengths. So as such it is not practical to construct a 16’8” deep deck as 16’ joists will not make it, and you would have to opt out for paying a premium to longer boards or adding another beam. The ...
Evolution beams are designed for long spans between support columns. Measuring 2 inches by 11 inches, the rectangular beams can be either a single or double, depending on the load and span. They can also function as either drop or flush beams. The longest beam span on this deck was 15 fe...
support wall 4, 5 to the expansion joint, and b the distance from the first support wall to the second support wall, it can be seen that the maximum moment M is sustained by the beam 8 over a length 2a, and that the shearing force V=M/b acts on the beam over the two lengths b...
Finally you can install the decking. The siding above should terminate slightly above the surface of the decking to allow air into the space. Just remember, if water gets into that intersection it’s now going to follow the plane of the drip cap and be pushed out away from the house. If...
conducted a numerical simulation of a ship fire after the cable pylon of the Vasco da Gama bridge was hit by ships and obtained the temperature field and fire resistance time of the main beam section of the cable-stayed bridge under such a fire scenario. Bennetts et al. [5] conducted a...
