Concentrated Loads A line load running parallel to the span should be treated as a series of concentrated loads. Slab on metal deck analysis and design (both composite and form deck) per SDI and ACI 318-99. Roof deck installation drawings shall be submitted to the project architect and engineer for approval prior to the manufacture of materials. No longer just a division between space. 6RF (LRFD) and 1. Typically, piles for residential use are hot-dipped galvanized steel (Figure 2). EVALUATION AND MODIFICATION OF OPEN-WEB STEEL JOISTS AND JOIST GIRDERS MARLON W. Slab on metal deck analysis and design (both composite and form deck) per SDI and ACI 318-99. Inspect the equipment's securement points for wear and damage. For the ultimate point load applied at 27 inches above the floor, the steel requirement would increase further for each strip. Point and impact loads Metal decking may mark if subjected to extreme point or impact load. We've run into this problem in the past, but to see the actual ribbed profile of the deck you simply have to revise a few options in the deck itself to make it show up. The profile may also be used as a permanent shuttering. If the deck is rated per sq foot or per square meter, structurally, it is assumed that the load is distributed within that span. The load combinations in Table 3. Design Load or Tested Load? Design loads specified in the code are often different from testing loads especially with wood. Braces are designed to transfer the horizontal loads to the base. Steel Deck. The beam would buckle in the lateral plane and deflect in the vertical plane. Draw the line load on the beam for clarity of what we are designing. STRUCTURAL ANALYSIS The addition of a green roof to the SLCC imposes additional gravity loads on the structure. EXAMPLE CALCULATIONS 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. In this example we used the ConstructionCalc Wood Beam Calculator to make the calculations for us so our deck doesn't collapse. These should be 16Ga with a 3/8" hole in them. Steel roof deck shall be placed in accordance with approved erection drawings.
