9. Steel Construction Flashcards
During the alloying process, elements are combined to produce an end result they can be used for a specific purpose.
Name these three alloys and their attributes:
Molybdenum- strength
Vanadium- strength and toughness
Manganese- resistance to abrasion

One common structural steel is ASTM A36 which includes:
Manganese, carbon, silicon

Steel expands as it is heated. The amount of expansion for slender members, such as beams and columns, can be determined through a property known as the:
Linear coefficient of thermal expansion

The most commonly used spray applied fire resistant materials (SFRM) are:
mineral fiber or expanded aggravate coating such as vermiculite or perlite.

Gypsum board containing additives to increase its fire resistance. Is usually required where a specific fire resistance is desired.
Type X

Within this connection type, sufficient rigidity exists between the beam and the column so that no change occurs in the angle between the beam and the column as the loads are applied.
Design to resist the BENDING forces resulting from the supported loads and lateral forces
Rigid frame

Reinforced walls located between columns and beams to brace the laterally.
Sheer panels

This can carry loads across greater spans more economically than beams can.
Steel truss

The top of a rigid frame is known as the _____ and the points were the incline members intersect the vertical members are known as the_____.
Crown
Knee
