Shear strength - 80% of solid deck slab Deflection - Similar to solid slab Weight - 40% below solid slab Fire Resistance 65% of solid slab. Bubble Deck slab belongs to a biaxial voided concrete slab in which high density polythene hollow sphere substitute the incompetent concrete in the middle of concrete slab.
Flat slab is a reinforced concrete slab supported directly by concrete columns without the use of beams. Flat slab is defined as one sided or two-sided support system with sheer load of the slab being concentrated on the supporting columns and a square slab called drop panels. Drop panels play
different between solid slab and ribbed hollow Comparison between Ribbed Slab Structure using Lightweight. Comparison . What is the difference between waffle slabs with solid heads and waffle slabs.
The solid slab was generated as a thick shell of pure concrete while the Bubble deck slab was designed as a layered shell. For simplicity in the Bubble deck model, a rectangular layer of HDPE was sandwiched in between two layers of standard concrete
Deck vs Slab for observatory construction. changing mounts and/or adding different mounts by using production tripods/portable piers. so far and a solid slab
Solid slab 100 Bubbledeck slab 75 Table 7. It is calculated to 81% compared to solid slab. Shear strength of slab mainly depends on effective mass of concrete. due to use of plastic bubbles, the shear resistance of bubbleDeck greatly reduces in comparison of solid slabs 10 Bending Strength and Deflection Behaviour In % of a solid deck
Deck is basically an open outdoor platform without a roof which extends from the house. A deck could be composed of materials such as metal or plywood. While slab on the other hand is an outer extent of the diaphragm within a building, a slab section can be utilized for modeling a simple floor or roof slab.
Structural behavior of bubble deck slab. This study showed that bending stresses, deflections, and shear resistance are slightly different than those for solid slab systems, in the range of 5
Deck slabs can be precast. Poissons Ratio 0.18 Plastic HDPE Modulus of Elasticity E 1035 MPa Density 970 Kg/m3 Poissons Ratio 0.4 slab. 5. ADVANTAGES OF BUBBLE DECK Material And Weight Reduction The prevailing beneficial of a Bubble Deck slab is that it uses 30-50% less concrete than normal solid slabs.
Different Types of concrete slabs in construction:-There are 16 different types of Slabs in Construction. Some of them are outdated and many of them are frequently used everywhere. In this article, ill give a detailed explanation of each slab where to use particular slab. Below are the types of concrete slabs.
The design principles of a solid slab bridge deck may be illustrated by the following illustrative example: Illustrative Example 1 : Design a solid slab bridge superstructure having a clear span of 9.0 metres and carriageway of 7.5 metres with 1.5 metres wide footway on either side for a National Highway.
The ultimate concrete formwork system to form bridge-decks and large slabs, adaptable to different configurations. solid or hollow Bridges of variable deck
Millions of square feet of suspended concrete slabs are placed every year in the U.S., much of it on a structural steel frame and metal deck. When the designer specifies these slabs, there is sometimes a misconception that it can meet the same requirements as a slab on ground. It cant. The
different between solid slab and hollow slab Hollow-core slab - Wikipedia, the free encyclopedia This makes the slab much lighter than a massive solid concrete floor slab of equal , The slabs are typically 120 cm wide with standard thicknesses between 15 cm , of
Solid slab deck type solid concrete with no metal deck -- For the Solid Slab deck Type, specify the Slab Depth tc not including the height of the metal deck,and the Shear Stud Diameter, Height hs after welding and Tensile Strength Fu .
Bubble deck slab is a method of virtually eliminating all concrete from the middle of a floor slab, which is not performing any structural function, thereby dramatically reducing structural dead
Analytical Study of Solid Slab with Different Types of Cavity Mrs. Kavita Golghate1, reduces the concrete more than cobiax and the bubble deck slab system.
A Comparative Design of Reinforced Concrete Solid Slab Bridge for Different Spans Bridge Deck Behavior by E. C. Hambly.
difference between precast slab and composite deck. 6,000 psi mix design and the deck slab concrete may different between solid slab and ribbed hollow slab.
Typically, the slab and/or beam thickness is determined first to ensure that the deflection requirements of ACI 318-05, Section 9.5 are satisfied. For solid, one-way slabs and beams that are not supporting or attached to partitions or other construction likely to be damaged by large deflections, Table 9.5 a may be used to
The durability of bubble deck slab is not fundamentally different from ordinary solid slabs. The concrete is standard structural grade concrete and combined with adequate bar cover determined in accordance with EC2 or BS811O 5 provides most control of durability commensurate with normal standards for solid slabs.
