Composite Properties (for composite design)

SettingDescription
Concrete Thickness This is the concrete thickness that exists above the flutes of the metal deck. The thickness is shown for the left and right side of the beam in case differences occur.
Unit Weight of Concrete This is the weight of the concrete. The weight is given for the left and right side of the beam in case differences occur.
f'c This is the strength of the concrete. The strength is given for the left and right side of the beam in case differences occur.
Decking Orientation This is the angle of the metal deck span, measured in degrees, from the referenced beam. The angle is given for the left and right side of the beam in case differences occur. The deck span will be considered "Parallel" with a beam if it is oriented within 10 degrees of that beam.
Decking Type This is the type of deck that was selected by the user. The deck type is given for the left and right side of the beam in case differences occur.
beff This is the effective concrete flange width used in the composite design of the beam.
Y bar This is the distance from the bottom of the steel beam to the neutral axis of the composite section used for deflection calculations.
Seff This represents the effective section modulus of the composite section for partial composite action.
Str This represents the section modulus for the transformed composite section referenced from the bottom flange of the steel beam.
Ieff This represents the effective moment of inertia of the composite section for partial composite action.
Itr This represents the moment of inertia for the transformed composite section.
Stud Length This is the nominal length of shear stud as selected by the user.
Stud Diameter This is the nominal diameter of the shear stud as selected by the user.
Stud Capacity (q) This is the shear capacity of a single shear stud. When multiple rows of studs are required, the shear capacity of a stud in a single row is indicated by q[1], that of a stud in a double row by q[2], and that of a stud in a triple row by q[3].
# of Studs This is the number of studs required for the design of the beam. The number of studs is given for full composite action (or maximum, if full composite action cannot be obtained), partial composite action and the actual number used. Unless otherwise specified by the user the actual and the partial number of studs will be the same. When there exists a point load on the designed beam, a series of studs may be listed with a comma separating them. Each number represents the number of studs required between each point load or segment, starting at the left support.
Number of Stud Rows This is the number of rows of studs necessary to place the number of studs called for.
Percent of Full Composite Action This is the percent of full composite action that will be obtained if the number and distribution of studs conform to that specified for Actual.
