How thick is concrete metal deck?
Dimensionally, a concrete deck is typically thicker with a minimum thickness of 3 1/2” accounting for the roof deck and concrete thickness over the top. Steel deck can be up to 2 1/4” thick for a roof deck/Resindek® system or as little as 1/4” thick with a floor plate system.
What is slab on metal deck?
Slab Mixes and Fresh Concrete Properties for Pumpable Decks Oftentimes, a hybrid of synthetic fibers and steel reinforcement is an integral component of a warehouse slab on metal deck design due to the crack minimization provided. Pumpability and finishibility are the main drivers in developing the concrete mix design.
What is the minimum bearing for metal deck?
1-1/2″
A minimum of 1-1/2″ of end bearing should be provided for metal roof decking or metal floor decking. If there is less than 1-1/2″ of bearing, additional fastening should be provided and the deck end load capacity should be checked.
How far can pan deck span?
composite deck, typical spans are 10 ft to 15 ft. “When you use a dove- tail profile, you can span 15 ft., but you have to shore it,” notes Abbata.
How do you build a composite slab for a steel deck?
The steps in the design of profile metal decking for composite floors are;
- Determine the effective breadth of the concrete slab.
- Calculate the moment capacity of the section.
- Evaluate the shear capacity of the section.
- Design the shear connectors.
- Assess the longitudinal shear capacity of the section.
- Check deflection.
What is a concrete pan deck?
Pan decking is a corrugated sheet metal designed to have structural concrete poured over top it. It’s a stay in place form that will support the concrete while it cures.
How far can corrugated metal decking span?
Based on a standard profile of about 2 in. to 3 in. composite deck, typical spans are 10 ft to 15 ft. “When you use a dove- tail profile, you can span 15 ft., but you have to shore it,” notes Abbata.
Is steel decking structural?
What is Steel Decking? Metal deck is a key Structural Building Component in steel construction. Metal Deck is made by rolling steel coil to corrugated rolled to a specified geometry. Thus, deck is made by cold forming structural grade steel coils into a pattern of flutes and ribs into various shapes.
What is a steel deck floor system?
Steel deck designs maximize the efficiency of steel’s properties, resulting in high strength-to-weight ratios. Because fluted decks displace concrete, a composite steel deck floor system uses less concrete compared to conventional flat plate slabs, meaning: smaller primary structures and foundations.
How far can you span concrete deck?
Capable of open spans of up to 60 feet and beyond, composite steel joist and steel deck long-span composite floor systems provide design flexibility while introducing a range of cost and performance enhancements.
How do you calculate a concrete slab for a metal deck?
The concrete volume, in cubic feet per square foot, is equal to the concrete thickness above the flutes divided by 12 plus Cv. V = t / 12+Cv.
How do you load a structural deck profile?
Click in the Structural Deck layer and the Structural Deck Properties are available. Select a new deck profile. If a standalone deck is required, specify it under Deck Usage. Otherwise, click OK twice to apply the new deck profile.
How far can concrete span without support?
Reinforced concrete allows a wide range of structural options and provides cost-effective solutions for a multitude of situations—from residential buildings with moderate live loads and spans of about 25 ft, to commercial buildings with heavier live loads and spans ranging from 40 ft to 50 ft and beyond.
What is the width of steel deck?
Standard deck width varies with the product used but full sheets are usually 12”, 18”, 24”, 30” or 36”.
How thick should a concrete beam be?
There is a certain rules and guidelines, As per IS 456:2000, minimum depth/thickness of a RCC beam should not be less than 9″ (230mm), hence minimum depth/thickness of RCC beam is 9″ (230mm) thick, provided minimum size 9″×9, use of M20 grade of concrete with 2nos of T12 at bottom as tension bar and T10 at top.
