Design Strength of Axially Loaded Composite Column Solution

STEP 0: Pre-Calculation Summary

Formula Used

Nominal Load = 0.85*Gross Area of Steel Core*Critical Compressive Stress/Resistance Factor
P_n = 0.85*A_Gross*F_cr/Φ
This formula uses 4 Variables

Variables Used

Nominal Load - (Measured in Newton) - The Nominal Load for design should be according to the applicable code or specification under which the structure is designed or as dictated by the conditions involved.
Gross Area of Steel Core - (Measured in Square Millimeter) - Gross Area of Steel Core is the total area enclosed by the walls. Net area is the usable area.
Critical Compressive Stress - (Measured in Megapascal) - The Critical Compressive Stress is the force that is responsible for the deformation of the material such that the volume of the material reduces.
Resistance Factor - The Resistance Factor accounts for the possible conditions that the actual fastener strength may be less than the calculated strength value. It is given by AISC LFRD.

STEP 1: Convert Input(s) to Base Unit

Gross Area of Steel Core: 51 Square Millimeter --> 51 Square Millimeter No Conversion Required
Critical Compressive Stress: 60 Megapascal --> 60 Megapascal No Conversion Required
Resistance Factor: 0.85 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_n = 0.85*A_Gross*F_cr/Φ --> 0.85*51*60/0.85

Evaluating ... ...

P_n = 3060

STEP 3: Convert Result to Output's Unit

3060 Newton --> No Conversion Required

FINAL ANSWER

3060 Newton <-- Nominal Load

Define Design Strength?

The load-bearing capacity of a member is computed on the basis of the allowable stresses which are assumed in design. The assumed values for the strength of concrete, and the yield stress of steel on which the theoretical ultimate strength of a section is computed.

Define a Column?

A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest.
