The loads on a bridge deck are made up of: Self weight; the weight of the bare concrete structure. 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. Building materials are not dead loads until constructed in permanent position. ... • DW: Dead Load of wearing surface and utilities. concentrated load on one foot of deck width. The load that each deck support column and the ledger are carrying is shown in different colors as the individual load areas. per sq. For a Group 4 type structure (see fig. Connection Details 6′ and Joist Span per square foot. ft. of floor area Dead load on second floor = 20 lbs. 0.005 ksf * 1 ft. = Typical Section. 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 … 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. Where I live and work, in the Minneapolis area, we need to build decks to support 50 lbs. ft. (Storage space.) Hence, the loads considered on the arch bridge are the self weight, UDL traffic action, and wheel load traffic action. 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. nominal thickness) 40 Glass (per 1-in. Where possible, the values were taken directly from manufacturer technical data sheets and are the actual weights of specific, representative products. For example: • The wheel load of rolling equipment on the steel deck during roofing material installation. The uniform load moment coefficients assumed in the calcula-tions … Let us see how these loads are calculated. 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. Joist dimensions are only part of the equation. dead load. 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 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. 2.2.3 ASSESSMENT OF DEAD 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. 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 following table provides typical weights (dead load, self-weight) for various roofing materials. Part 2 The dead load of structural concrete slabs varies considerably with concrete type. is considered “live load.” thickness) 15 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. ft. 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. building a deck platform to support hot tub. per sq. 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. EXAMPLE 6 - , A 7 & 10M 3 2018 Results of analysis: Engineers must estimate the traffic loading. Note, that the load for area 2 and 4 are the same. 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. 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. • The large spacing between attachments of roofing material to steel deck under uplift conditions. ft. of floor area Dead load of partitions = 20 lbs. Dead load of partitions = 20 lbs. Loads can be defined and applied to the model graphically or from within the spreadsheets. Dead loads are also known as permanent or static loads. ft. Dead load of attic floor when floored = 20 lbs. 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. The might of the dead load, or lack thereof, often defines how much live load it can handle. Dead Loads - Precast ,Composite and Composite Additional Dead Load.
