Chapter 3: Structural Design Features Flashcards
The direction of force is from loads acting on the interior of structural members is expressed as?
Stress
One common type of reaction is a_____within a horizontal structural component that is loaded vertically.
Bending moment
Stressors within a material are classified according to the direction of force.
Tension
Compression
Shear
The total structures within a structural member must be lower than the_____of the material for the structure to remain intact.
Failure point
A____load is not fixed or permanent.
Live load
A____load is fixed and location and quantifiable.
Dead load
_______Loads are steady or are applied gradually.
Static load
__________Load involve motion and are capable of delivering energy greatly in excess of the weight of the object involved.
Dynamic load
Wind may produce a suction affect on the downside of the building resulting in outward pressure, what is this referred as?
Negative pressure
An____is a curved structural member with primarily compressive interior stresses.
Arch
_______Are frame structural unit made up of a group of triangles in one plane.
Trusses
The top and bottom members of a truss are called?
Chords
__________are three dimensional trust structures.
Space frames
_________Are commonly place at the exterior of a structure, but they may also include internal walls.
Load bearing walls
Bearing wall structures use walls to support spanning elements, including?
Beams
Trusses
Precast concrete slabs
What type of roof trusses have curved top chords,that are unavoidably subject it to bending stresses?
Bowstring truss
And steel stud wall construction studs are placed 12 to how many inches apart?
