Chapter 2 Concepts of Construction Flashcards
The force per unit area that produces a deformation
Stress
A term meaning 1000 pounds is used in engineering calculations where the number would be so large as to be unwieldy
KIP
The actual percentage of elongation that occurs when a material is stressed
Strain
These occur within a building member when opposing forces pull the member in opposite directions and are often the result of wind loads
Shear forces
The weight of the building itself and any equipment permanently attached to it or built in
Dead load
Loads that are delivered in a short time
Impact loads
Loads that are applied intermittently
Repeated loads
These are installed in buildings to resist lateral loads from wind and earthquakes
Shear walls
The term _________ refers to a force causing rotation of the structural member around a fixed point of connection where the force is applied some distance from the fixed point
Moment
Heavy riveting of girders two columns from top to bottom of the frame
Portal bracing
_________ floors are designed to stiffen the building against the wind and other lateral loads such as earthquakes
Diaphragm
Externally braced buildings are known as _________
Tube construction
A force that is perpendicular to the plane of the section but does not pass through the center of the section
Eccentric load
A _________ is made by sandwiching a piece of steel between two wooden beams
Flitch plate girder
A 1 X 4” Beam spanning 6 feet can carry _________
533lbs
