Integration with Building Systems and Construction 25% (Structural Systems) Flashcards
Load Bearing
Elements capable of bearing a structural load
Walls that carry the weight
Non Load Bearing
Elements that ONLY support iteself
Does not help the structure stand up
Dead loads
Static Loads
Non movable loades
Floor, pillars, roof
Live loads
AKA Dynamic Loads
Non permanent loads, movable
People, furniture, equipment.
Gravity loads
- Dead load
- Live loads
Loads that exert downwards force
Lateral Loads
Load force from natrual occurrences
Wind, earthquakes, explosions
Dynamic loads
Impact loads
Loads created from impacts of moving/stopping objects
Elevators, snow loads, car
Change more quickly
Structural Systems
Open Web Steel Joist
Steel Structure
Open webbing of joist, provide light struture that is easily penetrated by mechanical systems
Found in one story or low-rise bldg
Structural Systems
Post & Beam
Steel Structure
Consists of steel, concrete or timber columns (posts) supporting a grid of beams (flooring)
Used for bldgs of 3 stories or less
Structural Systems
Beam & Girder
Steel Structure
Girders
* Main horizontal supports
Beams
* Connected to girders and carry floor loads/transfer loads to the girders
Can be made of concrete or steel
Used: Mid-high rise office bldgs
Structural Systems
Post Tensioned
Concrete System
Stretched steel cables within the concrete
Should not be penetrated for pipes or conduit
Structural Systems
Flat Plate (Cast in Place)
Concrete System
- Low to med. rise construction
- Moderate spans most economical floor system
- Minimum thickeness
Hotels, motels, dorms, condos, hospitals
Structural Systems
Flat Slab (Cast in Place)
Concrete System
- Best for suppporting heavy loads
- Economical for live loads more than 150 psi
Warehouse, industrial stuctures, parking structures
Structural Systems
Waffle Slab (Cast in Place)
Concrete Structure
- Columns with drop panels
- Longer two-way spaces
- Heavy load capacity
Warehouses, industrial structures, parking structures
Structural Systems
Precast Concrete
Conrete Structures
- Cured off-site and shipped
- Similar to LEGOS
- Short lead times/increase durability
Low to mid rise buildings, apartments, offices, hotels
Structural Systems
Concrete Block
Masonry
- Load bearing walls
- Made up of stone, bricks or blocks
Glass blocks
When you have minor movement in walls, what kind of joint should be used?
Slip joint
When you have major movement in walls, what kind of joint should be used?
Expansion joint
Where are control joints used?
When masonry shrinks
