Beams, Joists, Girders, and Floors Flashcards
Vernacular term for Beam
Biga
Vernacular term for Joists
Suleras
Vernacular term for Girder
Guililan
Rigid structural member that carries and transfers transverse loads across space to supporting elements
Beams
“Biga”
any of a series of small, parallel beams for supporting floors, ceiling, or flat roofs
Joists
“Suleras”
a large principal beam that supports concentrated loads at isolated points along its length
Girder
“Guililan”
beams having a single span w/ a support at each end
Simple Beams
beams supported at one end only
Cantilever Beams
beams resting on more than two supports
Continuous Beams
Material for beams, girders, and joists that has a steel plate
Flitch Plate
compressive stresses is resisted by the ____ and all the tension resisted by the ____
Concrete
Steel
the section of a beam at w/c the bending moment changes from positive to negative
Point of Inflection
handles the diagonal tension at beam supports
Stirrups
300M x 400M Beam
Rectangular Beam
Type of RC beam where a reinforced concrete floor slab and is supporting beam are built at the same time
T-Beams
used when the cross-sectional dimensions of the beam are limited so that there is an insufficient concrete area for the compressive stresses
Beam w/ Compression Reinforcement
Doubly Reinforced Beams
beams supported at one end only
tensile reinforcement is located on top of the beam and inverted U-stirrups are provided
Cantilever Beams
double reinforced beams used for long spans
Hollowed center to reduce dead load
Diaphragms provided at intervals
Hollow Box Girders
short beam extensions from columns used to support rafters or trusses
Beam Brackets / Corbels
ideal type of steel Beam
I-Beam
a beam composed of a wide plate (__) at the top and bottom of w/c are riveted angles and plates
Simplest type (a web, 4 flange angles)
Plate Girders
web can be reinforced against buckling by angles riveted to its sides
Stiffener Angles
a built up beam in w/c more than 1 web plate is used
Box Girders
lightweight, shop fabricated steel members having a trussed web
permits the passage of mechanical services
Open Web Steel Joists
has a web consisting of a single bent bar, running in a zigzag pattern bet, the upper and lower chords
K-series Joist
thin steel sheets manufactured from cold forms sheet or strip steel
an economical floor system that is lightweight, non combustible, and damp proof
Light Gauge Steel Joists
may be built up of angles and plates riveted together for long spans and for unusual cases of very heavy loading
Girder
