load capacity of timber decking

Specification for Deck Boards | Timber DeckingThe higher strength classes, typically C18 and C24 should be specified where smaller component sections, longer spans or commercial deck performance design considerations are required. For decks below 600mm in height the use of C16 timber is also recommended. Note: (i) Do not exceed the recommended load and span for each strength class refer to span tables in TDCA/TRADA timber decking: The ...

Timber Bridges - Forest Products Laboratory - Forest ServiceLongitudinal stress-laminated deck superstructures consist of a series of lumber laminations that are placed edgewise between supports and are compressed transversely with high-strength prestressing elements. (Figure 9-1). The bridges are similar in configuration to glulam or nail- laminated longitudinal decks previously discussed; however, with stress- laminated decks the load transfer between laminations is developed totally by compression and friction between the laminations, ...

How to Build a Deck - Softwoods12 Apr 2011 ... The load that you put onto your deck can at times be very large indeed, so correct calculations of the stiffness and strength of the internal timbers of your deck are essential. The flexibility of timbers and their strength is taken into account in the Australian timber framing code that is used to create span tables for both Bearers and Joists. Selecting the correct timbers and the layout of your deck is relatively simple once you are able to interpret these tables which are based ...

Boral Decking | BoralA hardwood timber deck provides a way to enhance any home, garden, commercial or retail property. A hardwood timber deck creates a comfortable, attractive and flexible feature that can be added to any kind of flat, sloping, wet or even waterside site. Boral timber's commercial decking is ideal for applications such as boardwalks, pedestrian and light vehicle bridges, loading docks and grandstands. The 135 x 32mm sized boards boast a greater load capacity.

STRUCTURAL TIMBERS | Products | ProductsThe rating and profile of structural components relies most importantly on spans and loadings. Material used on the deck, location and landscape, design and deck related bushfire risk are also key considerations. Treated softwood (H3, H4 and H5) structural timber is used in most decking situations with Hardwood and Engineered beams also consistently used. Span tables are available here. For alternative sizes, spans and stress grades or for members supporting roof loads, refer to ...

Calculate Deck Load Capacity - Tributary Area - DecksGoWhat a great question. The issues around deck load capacity is one I receive often from visitors asking how much weight they should design their deck for. The discussion quickly leads to the overall strength of the framed structure. But that is only one part of it. That's because any analysis of what load a structure may bear upon itself and its foundation must involve the support post network and soil bearing capacity.

Types of Timber Bridges - Forest Products Laboratory - Forest Servicethe beam, deck (slab), truss, arch, and suspension superstructures. The substructure is the portion of the bridge that transmits loads from the superstructure to the supporting rock or soil. timber substructures include abutments and bents. Abutments support the two bridge ends, while bents provide intermediate support for multiple-span crossings. Figure 2-1.- Basic components of a timber bridge. This chapter provides an introduction to the many types of timber bridges currently used in ...

Deck Load Calculator - DecksGoThis calculator determines the size of each tributary area of your deck. It then determines the total load from each tributary area based on the design load of your deck. Default is 50 psf which you can change. The total load for each tributary area is then divided by the area of each footing in order to determine the load psf imposed on the soil. This value must not be greater than the bearing capacity of the soil. If it is, you must increase the size of the footing to spread the weight out over a ...
