Compressive Stress when Flat Width Ratio is between 10 and 25

Formula

f c = (\frac{5 \cdot f b}{3}) - 8640 - ((\frac{1}{15}) \cdot (f b - 12950) \cdot w t)

Example

18.58333 kN/m² = (\frac{5 \cdot 20 kN/m²}{3}) - 8640 - ((\frac{1}{15}) \cdot (20 kN/m² - 12950) \cdot 13)

Compressive Stress when Flat Width Ratio is between 10 and 25 Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Compressive Stress of Concrete = ((5*Design Stress)/3)-8640-((1/15)*(Design Stress-12950)*Flat Width Ratio)
f_c = ((5*f_b)/3)-8640-((1/15)*(f_b-12950)*w_t)
This formula uses 3 Variables

Variables Used

Maximum Compressive Stress of Concrete - (Measured in Pascal) - Maximum Compressive Stress of Concrete is the maximum stress that, under a gradually applied load, a given solid material can sustain without fracture.
Design Stress - (Measured in Pascal) - Design Stress is the stress in which the factor of safety can be incurred.
Flat Width Ratio - Flat Width Ratio is the ratio of width w of a single flat element to the thickness t of the element.

STEP 1: Convert Input(s) to Base Unit

Design Stress: 20 Kilonewton per Square Meter --> 20000 Pascal (Check conversion here)
Flat Width Ratio: 13 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_c = ((5*f_b)/3)-8640-((1/15)*(f_b-12950)*w_t) --> ((5*20000)/3)-8640-((1/15)*(20000-12950)*13)

Evaluating ... ...

f_c = 18583.3333333333

STEP 3: Convert Result to Output's Unit

18583.3333333333 Pascal -->18.5833333333333 Kilonewton per Square Meter (Check conversion here)

FINAL ANSWER

18.5833333333333 ≈ 18.58333 Kilonewton per Square Meter <-- Maximum Compressive Stress of Concrete

Flat Width Ratio of Stiffened Element using Moment of Inertia

Go Flat Width Ratio = sqrt((Minimum Area Moment of Inertia/(1.83*Thickness of Steel Compression Element^4))^2+144)

Minimum Allowable Moment of Inertia

Go Minimum Area Moment of Inertia = 1.83*(Thickness of Steel Compression Element^4)*sqrt((Flat Width Ratio^2)-144)

Nominal Strength using Allowable Design Strength

Go Nominal Strength = Safety Factor for Design Strength*Allowable Design Strength

Allowable Design Strength

Go Allowable Design Strength = Nominal Strength/Safety Factor for Design Strength

What are the failures in beams using Cold Formed Structures?

The Web crushing: This may occur under concentrated loads or at support point when deep slender webs are employed.
Shear buckling: Thin webs subjected to predominant shear will buckle or bend outwards.
Lateral buckling: Occurs to long beams along with twisting.
