Plate Length Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bearing or Plate Length = sqrt(Area required by Bearing Plate)+(0.5*((0.95*Column Depth)-(0.80*Width of Plate)))
N = sqrt(A₁)+(0.5*((0.95*d)-(0.80*B)))
This formula uses 1 Functions, 4 Variables

Functions Used

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., sqrt(Number)

Variables Used

Bearing or Plate Length - (Measured in Meter) - Bearing or Plate Length is the length along the beam under which a high concentration of stresses due to concentrated loads is transferred to the supporting structure below.
Area required by Bearing Plate - (Measured in Square Meter) - Area required by Bearing Plate is the space occupied by the bearing plate on concrete.
Column Depth - (Measured in Meter) - Column Depth is the horizontal length of column cross section.
Width of Plate - (Measured in Meter) - Width of Plate is one of the surface dimensions of a flat, solid plate, typically measured in millimeters or inches. It is one of the larger surface dimensions, while thickness is smaller dimension.

STEP 1: Convert Input(s) to Base Unit

Area required by Bearing Plate: 23980 Square Millimeter --> 0.02398 Square Meter (Check conversion here)
Column Depth: 140 Millimeter --> 0.14 Meter (Check conversion here)
Width of Plate: 150 Millimeter --> 0.15 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N = sqrt(A₁)+(0.5*((0.95*d)-(0.80*B))) --> sqrt(0.02398)+(0.5*((0.95*0.14)-(0.80*0.15)))

Evaluating ... ...

N = 0.161354770672395

STEP 3: Convert Result to Output's Unit

0.161354770672395 Meter -->161.354770672395 Millimeter (Check conversion here)

FINAL ANSWER

161.354770672395 ≈ 161.3548 Millimeter <-- Bearing or Plate Length

What is Base Plate & types of Columns based on Slenderness Ratio?

The Base plates are usually used to distribute column loads over a large enough area of supporting concrete construction that the design bearing strength of the concrete is not exceeded. It acts as a support to transfer the compression load acting over the columns. Column bases are usually assumed to be subject to axial compression and shear only.
Types of columns are as follows:
Long or Slender column: Length is more than critical buckling length and hence fails due to buckling.
Short column: The length is less than the critical buckling length and it fails by shearing.

What is the difference between Columns and Struts?

The Strut is mainly used in roof trusses and steel bridges. The main purpose of a strut is to maintain the rigidity of the structure and to take compressive force and is not designed to take any gravity load, but
the column is designed for various types of loads acting on it such as axial load bending moment gravity load shear forces buckling and horizontal load like earthquake load and wind load.
Both Column and Strut are comprehensive members but the main difference between them is column is a comprehensive member of the frame structure and the strut is a comprehensive member of the truss structure.
