Ch.12 Structural Systems Flashcards
Type of structure consisting of steel, concrete, or timber column supporting a grade of beams on which the flooring is applied. Country concrete structures may consist of concrete columns supporting concrete for slabs. Solid concrete walls are typically used as a lateral sheer walls to transfer lateral mode, such as wind and seismic forces, to the foundation. In areas were building code require a seismic design iMessages California, diagonal steel bracing is often used in place of water in addition to concrete walls for lateral seismic support.
Post and beam construction
What are the two most common steel structural systems
beam and girder and open web steel joist
In the structural system large members, call girders, span between columns, and smaller beams are framed into them. Girders fan shorter distances because they carry the water weight of the beams. The beam spans the longer distances and are framed into the girders. Typical spans for the system or 25 feet to 40 feet, with the beam spaced about 8 to 10 feet on center. The steel framing is usually covered with a steel decking, which bands between the beams. A concrete topping is poured over the decking to complete the floor slab. This type of construction is commonly found in mid to high rise office buildings
Beam and girder system
Joists stay in between beams or bearing walls, also shown in the figure. Various types of open Web joists and span from 20 feet up to 140 feet. Depth range from 8 inches to 72 inches. joists are typically spaced 2 to 6 feet on center. As with a beam on girder system, steel decking span between a joist, and concrete slab is poured on top of the decking.
Open web steel joist system
Where are open Web steel Joyce typically located
In one story or low rise buildings with a wide calm spacing.
What are the two primary types of concrete structural systems
Precast and cast in place
But this time concrete structural system concrete is poured into forms red hardens before the forms are removed.
Cast in place
What this type of concrete structural system components are usually formed in a plant and shipped to the job site, where they are set in place and rigidly connected to. Form the structure
Precast
Steel cables within the concrete or tightened after the concrete sets, creating extra compression forces in the beginning or slab. 
Post tensioned 
What are the five basic cast in place systems
Beam and girder system, concrete joist system, flat plate construction, flat slab construction, and waffle slab system
This concrete system functions in a manner so similar to a steel system in which the slab is supported by intermediate beans, which I carried by larger girders. The slab is poured integrally with the beams
Beam and girder system
This concrete system is compromised of concrete members page 24 or 36 inches apart, running in one direction, which frame into larger beams. The slabs of support integrally with the joist. Because their choice are close together, it is more difficult to drill holes for small pipes and conduits.
Concrete joist system
This type of concrete system consists of a floor slab is designed and reinforced to transfer loads directly to the columns, which generally do not exceed 25 feet spacing. This type of construction is commonly used in situations where floor to floor height must be kept to a minimum. Because of the closely space reinforcing required, it is often difficult, but not impossible to drill these types of floors for electrical Service or small pipes
Flat plate construction
With this type of concrete construction it is similar to flat plate, except the drop panels are used to increase strength. Sometimes the truncated pyramids or cones are used instead of drop panels.
Flat slab construction
This type of concrete system can provide support for heavy loads at slightly longer spans than flat slab system. These slabs are often left exposed, with lighting integrated into the coffers.
Waffle slab system
What are the precast concrete shapes
Single tee, double tee, hollow core slab
Popular forms of precast construction because they can simultaneously serve as beam and floor decking in our easy and fast to erect.
Single and Double tees
What type of construction is commonly found in industrial buildings, one and two-story commercial buildings, and parking garages
Double tee 
In contemporary construction, this is generally limited loadbearing walls. This includes a brick and concrete block, but due to high cost of brick, nearly all of this type of structure walls are both of concrete block. Rick is generally limited to use as a veneer Overwood schedules or over concrete block walls.
Masonry
 what are other names for concrete masonry unit
Concrete block, concrete unit masonry, CMU
What is one of the most common sizes for CMU
8 x 8 x 16“ which is actually 7 5/8 wide and 15 5/8 long
These type of war support loads from above. These include live loads, such as people in furniture and dad but such as weight of the structure itself. This type of war maybe concrete, masonry, or wood framing. Because if their nature is structural support, these type of walls cannot be moved were removed and can only be pierced for doors and other openings if the top of the opening it’s framed with an adequately engineered lintel or beam
load bearing wall
