Specifications. 3.2 Bending stress in the deck shall not exceed 0.6 times the yield strength with a maximum of 36 ksi. (250 MPa) under the combined loads of wet concrete, deck, and the following construction live loads: 20 pounds per square foot uniform load. (1 kPa) or 150 pound concentrated load on a 1'0 wide section..
Loads greater than 10 kPa (200 psf) are commonly the result of large concentrated moving loads. In such cases, contact Westform for additional design information. The steel deck provides the positive reinforcement for the simply supported composite slab and no additional reinforcing steel is required. To control shrinkage..
Oct 19, 2011 . The composite deck system is a slightly cheaper alternative to the one-way slab; however, it increases the depth of the floor system, therefore decreasing the clearance for bus travel. The thick slab and deck combination provides sufficient shear capacity for the concentrated loads put forth by the busses, the
Mar 5, 2002 . 2. Limit State of Strength. The strength of a composite slab is usually limited by one of the following resistance limit states: (a) shear-bond; (b) flexure of an under-reinforced section; (c) flexure of an over-reinforced section; and (d) punching shear with concentrated loads. 3. Loads and Safety Criterion
Point Loads on Composite Deck-Reinforced Slabs. The behavior of composite deck-reinforced floor systems under concentrated loads is described. Laboratory experiments show that these floor systems may have a considerably larger capacity to support concentrated loads than indicated by existing design techniques
ABSTRACT ii. Load Distribution on Timber-Concrete Composite Floors capable of predicting the percentage of load received by each beam in timber-concrete composite slabs when subjected to concentrated loads. This percentage is a function of the span, the beam position at the slab and the thickness of the concrete..
To describe the design of one-way spanning composite slabs, formed using profiled steel sheeting and a concrete topping, including consideration of ultimate and serviceability limit state design according .. Shear stresses between the steel and concrete increase in the zone between the concentrated load and the support

The criteria states, "Additional concrete dead load due to deflection of the deck shall be considered in calculations." 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. concentrated load on one foot of deck width

The goal is to apply the insights of the research to the assessment practice for reinforced concrete slab bridges subjected to composite dead load and live loads. Therefore, the application to existing slab bridges is studied. Additional attention is paid to the horizontal load distribution of concentrated loads on slabs,..
Sep 29, 2017 . I-section profiles. Initial studies on the slab durability and its behavior under concentrated loads have also been performed . As this slab system is lighter and slenderer as compared to conventional reinforced concrete slabs, it becomes necessary to verify its behavior under dynamic loading. J. Compos
Bulk retail projects require robust floor systems capable of sustaining high floor loading including concentrated loads from racking systems. STEELDECK: Design Guide for Concentrated Loads on Metal Deck Slabs (SCNZ - 11:2006) has been prepared to assist structural engineers design metal deck slabs for this and other..
Design reinforcement at openings in slab. Check composite slab and design reinforcement. For composite beams: Determine shear connector layout and design transverse reinforcement. Consider: Fire resistance period. In-service loading, e.g. solid partitions, concentrated loads. Temporary construction loading, e.g. from
Q: Can we use a scissor lift on the slab? Where can I find information related to concentrated loads on slabs? The slab must be designed with the required capacity to support anticipated loading, such as a scissor lift. The Structural Engineer of Record (SER) is responsible for the design of slabs on steel deck and should be..
