Slenderness Ratio

Slenderness ratio, or simply slenderness is an aspect ratio, the quotient between the height and the width of a building.

Symbol: R_B

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Slenderness Ratio

Effective Length

The effective length is given in terms of the unsupported length of the beam. Unsupported length is the distance between supports and adequate bracing is not installed elsewhere in the span.

Symbol: L_e

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Effective Length

Depth of Cross Section

Depth of Cross Section (Height), in (mm) defines the geometrical measure from head to foot or from base to top of the section considered.

Symbol: d

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Depth of Cross Section

Width of Cross Section

Width of Cross Section defines the geometric measurement or extent of the member from side to side.

Symbol: w

Measurement: LengthUnit: mm

Note: Value should be greater than 0.

Formulas to find Width of Cross Section

sqrt

A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number.
