What are double tee used for?

Double tees are used as both horizontal and vertical load-bearing members. The double tee is a suitable system for swimming pool roof framing. It offers superior corrosion and fire protection in comparison to steel joists.

What is the flat 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’.

What is Shell beam?

Stresscrete Shell Beams can be used in ductile moment resisting frames. They offer many advantages in building construction: Midspan propping can be eliminated to reduce dead load continuity moments and reinforcing steel congestion at beam to column joints. Less skilled labour is required onsite.

What are Shell beams?

Stresscrete Shell Beam floors are an innovative answer to one of the oldest problems – how to speed up and simplify floor construction without compromising effective engineering and building practice. They can be used in ductile moment resisting frames, and offer many advantages in building construction.

What are four different types of slab?

Concrete Slab Types – Construction, Cost, and Applications

• One-Way Slabs on Beams.
• One-way joist slab (Ribbed slab)
• Waffle Slab (Grid slab)
• Flat Plates.
• Flat Slabs.
• Two-way Slabs on Beams.
• Hollow core slab.
• Hardy Slab.

What is a solid slab?

Solid Slabs are fully customizable concrete slabs of varying width, length and thickness. Solid Slabs can be designed and produced with mild reinforcing or by adding prestressing strands. Solid Slabs can be cast with specialty inserts for lifting, mounting or connecting hardware.

What is the advantage of T-beam?

T-beam casting with slab as we know so Its flange takes compressive stress and that mean It will resist more sagging moment of beam. Depth of beam is reduced as compare to ordinary beam so better headroom advantage. Over longer span T-beam is used rather than ordinary beam for reducing the deflection of beam.

Where are T sections used?

A T-beam (or tee beam), used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a T-shaped cross section. The top of the T-shaped cross section serves as a flange or compression member in resisting compressive stresses.

What are precast concrete double tees used for?

Precast concrete double-tees are commonly used for long- span floor systems in buildings and parking structures throughout the United States. Such systems are quick to erect, economical in cost, and help to resist lateral forces during seismic events.

What are the two parts of a double tees?

The two vertical leg sections are called webs or stems and the horizontal section is known as the deck or flange. Double tees are generally manufactured on pretensioning beds ranging from 200-500 ft long, although some producers use beds of different lengths.

What type of reinforcement is used for double tees?

For these systems, reinforcing bars are used to provide con- tinuity over the double-tees. As an alternative, systems con- sisting of a mechanical connection (category III) embedded in 4-in.-thick (100 mm) pretopped double-tee flanges are used.

What are the dimensions of a prestressed double tees?

Typical dimensions of prestressed double tees are: 1 Stem depth: 12-34 in. (up to 5 ft) 2 Flange width: 8-10 ft (up to 15 ft) 3 Span length: 25-55 ft (up to 80 ft or more)
