The loading includes the weight of the structure and other fixed weights which are defined as the dead load. Dead Load is the vertical load due to the weight of permanent structural and non‐structural components and attachments of a building such as walls, floors, ceilings, permanent partitions and fixed service equipment etc. Jointly gravity load and the lateral load should be resisted as it builds up acute pressures in a building. 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 ft. Live load and dead load. 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 … Dead load of attic floor, not floored = 10 lbs. per sq. per sq. A Vulcraft metal deck catalog has weights for various decks sizes and concrete fill combinations. Connection Details 6′ and Joist Span The load combinations are hard coded into the program based on the selected code. Superimposed dead loads; the weight of permanent loads applied to the bare concrete structure, such as parapets, footpaths, road surfacing etc. 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. 8000lb live load, 49 sq ft hot tub (7X7), ~160 psf live load plus 20 psf dead load. A typical wood-frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot; if there's wall-board covered ceiling suspended from the underside of that floor, the dead load increases to about 10 pounds per square foot. The specific method of attachment will determine the load distribution or effective width of deck to be used in the evaluation. The loads for areas 1 and 3 are different. Conspan Interpretation of Two Lanes travelling in one direction and two lanes on the other direction. The loads on a bridge deck are made up of: Self weight; the weight of the bare concrete structure. 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. The following table provides typical weights (dead load, self-weight) for various roofing materials. • The large spacing between attachments of roofing material to steel deck under uplift conditions. Building materials are not dead loads until constructed in permanent position. Hence, the loads considered on the arch bridge are the self weight, UDL traffic action, and wheel load traffic action. )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. Reinforced concrete creates the heaviest dead loads but also supports the most weight with its tremendous compressive strength. )–1 4 2.0 Clay tile 12.0 Clay tile with mortar 22.0 Slate ( -in. Joist dimensions are only part of the equation. Live load. ft. (Storage space.) thinking of having 3 beams underneath hot tub, double 2X12 southern pine, spanning 6', supported on each end by footings and 6X6 posts. Snow load will affect a deck’s weight load in a big way. Engineers must estimate the traffic loading. The roof is also a dead load. building a deck platform to support hot tub. Dead Loads - Precast ,Composite and Composite Additional Dead Load. Structural steel offers much less of a dead load and provides superior support for live loads in multi-story buildings. per sq. 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 … Let us see how these loads are calculated. per sq. per sq. structure and steel bracings in steel structure are extensively acceptable technique to place lateral load as a consequence of earthquake, wind, blast and so forth. Where possible, the values were taken directly from manufacturer technical data sheets and are the actual weights of specific, representative products. Loads. The load that each deck support column and the ledger are carrying is shown in different colors as the individual load areas. 0.005 ksf * 1 ft. = Typical Section. Based on the density mentioned above Super dead load like, wall load, floor finish, water proofing on terrace, water tank load comes is super dead load category. In many cases, ceiling joists for dead loads are designed to carry 10 pounds per square foot (psf), as opposed to the 40 or greater psf that live-load joists must carry. The might of the dead load, or lack thereof, often defines how much live load it can handle. By spanning a decking profile from rafter to rafter, the need for purlins can be eliminated in a portal frame design. The default footing assumes a 40 psf live load and 10 psf dead load over a tributary area of 18 inches and one-half of the maximum span of 13 feet–3 inches permitted for solid stringers. Dead load of partitions = 20 lbs. Stair stringers should be supported by bearing at the end where the stairway meets grade. This calculates to 500 pounds. ft. of floor area Dead load on second floor = 20 lbs. • 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 … concentrated load on one foot of deck width. For a Group 4 type structure (see fig. EXAMPLE 6 - , A 7 & 10M 3 2018 Results of analysis: the effects of those concentrated loads on the deck or composite deck-slab. 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. On short spans, it is possible that the maximum conceivable load will be achieved—that is to say, on spans of less than 30 metres (100 feet), four heavy trucks may cross at the same time, two in each direction. nominal thickness) 40 Glass (per 1-in. Loads on bridge decks. ft. of floor area Dead load of partitions = 20 lbs. Super dead load: Loading except the self-weight of structure is said to be super dead load. The dead load of structural concrete slabs varies considerably with concrete type. Note, that the load for area 2 and 4 are the same. 2.2.3 ASSESSMENT OF DEAD LOAD ft. Dead load of attic floor when floored = 20 lbs. The formulas used to determine the allowable uniform lo ads due to flex-ure (stress) and deflection are shown on page 6. Dead Load of floor maximum 40 kg/m2 (Covers standard residential deck materials, including possible plasterboard ceiling below) Live Load for decks & verandahs over 1m above ground level 2.0kPa (with a check on a concentrated live load of 1.8kN anywhere) ETH LAM GL beams are manufactured straight, without any camber built into the beams. per square foot. STRUCTURAL DECK PROFILES. Looking at Figure 3 we can instantly see that each deck support column is not carrying an equal load. 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 … Computing stresses at Top of Deck. The uniform load moment coefficients assumed in the calcula-tions … For this and all other example problems the following data from the Canam - United Steel Deck Design Manual and Catalog of Steel Deck Products will be used and are worked using LRFD methodology. Loads can be defined and applied to the model graphically or from within the spreadsheets. Table 4 lists the concrete weight to be added to the deck weight to determine slab dead load. is what we consider “dead load.” Then the remaining 10 lbs. Dead loads are also known as permanent or static loads. Note: The concrete weights listed in Table 4 do not include the allowance for deck deflection discussed on VF5 page 16. 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. • The footprint of a concentrated load on a slab. Part 2 A copy of the tables is provided in the Appendix and also ... Dead load moment = wtotall 2/8 = 1.2(44)(9)2(12)/8000 = 6.42 in.k Vertical Load Data – Siplast Inc Vertical Load Data .roofing gravel or ballast, and other local conditions. You also need to ensure that the joist spacing is adequate. In modern times, shear wall in R.C. 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 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. Live loads, or imposed loads, are temporary, of short duration, or a moving load. Where I live and work, in the Minneapolis area, we need to build decks to support 50 lbs. Simple – if 1.0 kPa is equivalent to 100 kg over 1.0 m2, then 2.0 kPa must be equivalent to 200 kg over 1.0 m2. ... • DW: Dead Load of wearing surface and utilities. DC = Dead Load from Bridge Members, Formwork, Deck, etc. thickness) 15 The primary function of a bridge is to carry traffic loads: heavy trucks, cars, and trains. To support 50 lbs., first consider that 40 lbs. Metal deck 3.0 Roll roofing 1.0 Shingles Asphalt ( -in. dead load. 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. IS875(part 1)-1987 give unit weight of building materials, parts, components. 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. There are a number of different Load Types that may used when loading the model. 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. 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. deck design load of 2 kPa? The dead load on a floor is determined by the materials used in the floor's construction. is considered “live load.” Assuming 1 1/2" composite metal deck with 2 1/2" normal weight concrete fill (4" total), the catalog gives a dead load of 39 psf.
