Vertical Load Data – Siplast Inc Vertical Load Data .roofing gravel or ballast, and other local conditions. If you are planning on building a raised deck it is important to determine the quantity, positioning and size of the structural members that will support the load of the deck, the dead load and the load created by the things that will go on the deck, including you and your guests which is the live load. )1– 4 10.0 Wood 3.0 Ceilings Acoustical fiber tile 1.0 Channel-suspended system Steel 2.0 Wood furring 2.0 Plaster on wood lath 8.0 Walls and partitions Brick (4-in. Engineers must estimate the traffic loading. DC = Dead Load from Bridge Members, Formwork, Deck, etc. To calculate the load, you should use 40lbs per square foot for live loads (these are variable loads that are dynamic such as the weight of people and furniture) and 15 lbs per square foot for dead loads (this is the weight of the materials used for the construction of the deck) for a total load … Dead load of attic floor, not floored = 10 lbs. There are a number of different Load Types that may used when loading the model. is what we consider “dead load.” Then the remaining 10 lbs. The bridge deck has been subjected to Load Model 1 on 2 notional lanes, and a remaining area of 2 m. The tandem load system on the bridge was modelled as a moving load on Staad Pro. building a deck platform to support hot tub. The next five steps calculate the positive moments due to dead load and the construction loads specified in the criteria namely: 20 PSF uniform load or 150 lb. STRUCTURAL DECK PROFILES. DC1 – Concrete = 150 lbs/ft3 DC2 – Stay-in-place Formwork = 15 psf DW = N/A for Non-Composite Construction CDL = Construction Equipment loads such as screed rails, overhang forms, temp railing, walkway CDL1 – Removable Coping Deck … Reinforced concrete creates the heaviest dead loads but also supports the most weight with its tremendous compressive strength. per sq. To put this into more practical terms, Even if you place a paddling pool on this deck it could tip the balance for a safe load, let alone a … ft. (Storage space.) )–1 4 2.0 Clay tile 12.0 Clay tile with mortar 22.0 Slate ( -in. Dead load of partitions = 20 lbs. IS875(part 1)-1987 give unit weight of building materials, parts, components. The distance you can span a 2-by-10 joist without additional support depends on the species and grade of the wood, how far apart the joists are and the expected load on the joists. Metal deck 3.0 Roll roofing 1.0 Shingles Asphalt ( -in. Dead loads are also known as permanent or static loads. ft. of floor area Dead load of partitions = 20 lbs. 8000lb live load, 49 sq ft hot tub (7X7), ~160 psf live load plus 20 psf dead load. To support 50 lbs., first consider that 40 lbs. thickness) 15 nominal thickness) 40 Glass (per 1-in. The following table provides typical weights (dead load, self-weight) for various roofing materials. per square foot. The load combinations are hard coded into the program based on the selected code. Nominal loading on 1m length of abutment: Deck Dead Load = (1900 + 320) / 11.6 = 191kN/m HA live Load on Deck = 1140 / 11.6 = 98kN/m HB live Load on Deck = 1940 / 11.6 = 167kN/m From BS 5400 Part 2 Figures 7 and 8 the minimum and maximum shade air temperatures are -19 and +37 o C respectively. ... • DW: Dead Load of wearing surface and utilities. In modern times, shear wall in R.C. Dead Load bending moments shown below are produced by a continuous beam model in CSiBridge 2017 using a uniform load for deck and wearing surface and a point load for barriers. ft. of floor area Dead load on second floor = 20 lbs. Table 4 lists the concrete weight to be added to the deck weight to determine slab dead load. Loads on bridge decks. per sq. Where possible, the values were taken directly from manufacturer technical data sheets and are the actual weights of specific, representative products. Stair stringers should be supported by bearing at the end where the stairway meets grade. By spanning a decking profile from rafter to rafter, the need for purlins can be eliminated in a portal frame design. The specific method of attachment will determine the load distribution or effective width of deck to be used in the evaluation. dead load. Since the load factors on combinations of Dead + Roof + Live loads can vary depending on the live load type or magnitude we took the conservative approach of treating all the live loads with the same load factor. A structural deck will perform the function of transferring dynamic and dead loads of the roof covering to the frame, and will also provide the necessary lateral restraint to the main structural frame. Superimposed dead loads; the weight of permanent loads applied to the bare concrete structure, such as parapets, footpaths, road surfacing etc. Part 2 Loads. Super dead load: Loading except the self-weight of structure is said to be super dead load. ft. • Ground snow load commonly ~ 10 psf • Usually roof live load governs unless snow drifts are considered Frost Heave • Condition where soil under footing freezes and exerts upward movement on the foundation • Bottom of Footings must be below frost depth to avoid this issue, commonly 12 … Structural steel offers much less of a dead load and provides superior support for live loads in multi-story buildings. Deck Ledger Connection to Band Joist a, b (Reference IRC Table R507.2 - Deck live load = 60 psf, deck dead load = 10 psf, snow load≤ 40 psf) For SI: 1 inch = 25.4 mm, 1 foot = 304.8 mm, 1 pound per square foot = 0.0479kPa. 2.2.3 ASSESSMENT OF DEAD LOAD Note: The concrete weights listed in Table 4 do not include the allowance for deck deflection discussed on VF5 page 16. 0.005 ksf * 1 ft. = Typical Section. ft. Dead load of attic floor when floored = 20 lbs. The reactions resulting from the dead load and live load specified in Table 1607.1, or the snow load specified in Section 1608, in accordance with Section 1605, acting on the cantilevered portion of the deck, and no live load or snow load on the remaining portion of the deck. The loads on a bridge deck are made up of: Self weight; the weight of the bare concrete structure. Hence, the loads considered on the arch bridge are the self weight, UDL traffic action, and wheel load traffic action. The loading includes the weight of the structure and other fixed weights which are defined as the dead load. Live loads, or imposed loads, are temporary, of short duration, or a moving load. For example: • The wheel load of rolling equipment on the steel deck during roofing material installation. Looking at Figure 3 we can instantly see that each deck support column is not carrying an equal load. The formulas used to determine the allowable uniform lo ads due to flex-ure (stress) and deflection are shown on page 6. Dead Loads - Precast ,Composite and Composite Additional Dead Load. For a Group 4 type structure (see fig. You also need to ensure that the joist spacing is adequate. • The large spacing between attachments of roofing material to steel deck under uplift conditions. the effects of those concentrated loads on the deck or composite deck-slab. EXAMPLE 6 - , A 7 & 10M 3 2018 Results of analysis: The dead load on a floor is determined by the materials used in the floor's construction. The might of the dead load, or lack thereof, often defines how much live load it can handle. Generally, vertical loads are resisted solely by the structural concrete deck or other structural consideration of the existing roof system in conjunction with the dead load imposed by the addition of a Siplast … Doc Viewer 4 2.0 Clay tile with mortar 22.0 Slate ( -in the primary of.
