What are the two main good qualities of steel?

What is the composite of a Frame?

What are the main type of Structural elements?

Which condition leads to the total loss of strength of steel structure?

Thirty-six kips per square inch (ksi) is equal to 250 MPa

There will be permanent deformation when steel is loaded below its yield point?

Steel breaks when loaded beyond its 'failure point.'

When steel is so loaded that it goes into its 'strain-hardening' range, it becomes brittle.

The modulus of elasticity of steel varies according to its yield strength (Fy).

What is the allowable shear stress for a steel with Fy=32ksi?

Which part of the steel section resists shearing stress in beams?

What is the formula associated with axial stress?

What steel section is composed of several plates that are welded together?

What is the meaning of LRFD?

Compression members are found in trusses.

Which range of stresses in steel will not result to permanent deformation?

A steel flag pole is a 'bi-athlete' structural element

What formula is associated with beam design?

Which one is the 'bi-athlete' structural element?

Using our understanding of how cantilevers reduce interior moment and deflection, we could create a series of cantilevers with hanging spans in a continuous system to maximize the use of materials. This combination of beams, referred to as?

Simplest from consists of two vertical poles with a horizontal pole spanning between them.

A vault created by a series of arches

A rotated arch; enclosed volume of space

Has the potential to become load-bearing; the space is not as flexible

Joists, rafter, girder, beams, transfer beams, plate girders, large built-up sections

the same members which have bending about two axes and compression or tension all at the same time

hangers

stress is directly proportional to the strain

Increase strength but loss of ductility

No permanent deformation

Deformation is permanent beyond

Rupture; breaking of the material

ASTM

Used for fabricating special members or to make gusset plates, stiffeners, and bearing plates

Is measured relatively to the yield strength

The ability of the wire to flow or yield under the constant stress created; can undergo plastic deformation after being stressed beyond elastic limit; opposite of brittleness

Are forces acting on a structural component and are represented as uniform on varying forces or points.

Permanent loads generated by the constructional system

Primarily horizontal but can induce vertical forces when blowing over surfaces

Forces acting horizontally or having a component which acts normal

Most common elements used in structures; primary bending members

Purely axially loaded member

Carries pure compression

Designed to work primarily as simply supported, uniformly loaded beams

Produced in av variety of shapes corresponding to the 3 basic construction method

Lateral stability provided in joists system

Structural components that are subjected to loads or components of loads which acts as perpendicular to their axis

A combination of Beams

The failure of web in pure compression

A state in which the web of the member will actually buckle under high localized loading

Used on the most ordinary buildings in the form of lintels

A type of built-up beam since it is fabricated by cutting an I and W shape along the web

Typically welded, but may be bolted or riveted to the flanges

Axially loaded members in compression

Focuses on the moment of inertia; the longer the column, the weaker it gets

AISC

Pure compression elements

Primarily gravity loads but in some instances. they may cause forces which act in some other direction

Works as deep as horizontal beams; rigid or flexible
