Length of Secondary Member using Collapse Prevention Level Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Secondary Member = (Collapse Prevention Level*10^7*Moment of Inertia of Primary Member)/(32*Length of Primary Member^4)
L_s = (C_p*10^7*I_p)/(32*L_p^4)
This formula uses 4 Variables

Variables Used

Length of Secondary Member - (Measured in Meter) - Length of Secondary Member can be described as the measurement of the secondary element in length.
Collapse Prevention Level - Collapse Prevention Level can be described as the building performance level which consists of the structural collapse prevention level with no consideration of nonstructural vulnerabilities.
Moment of Inertia of Primary Member - (Measured in Meter⁴ per Meter) - Moment of Inertia of Primary Member can be described as the quantity expressed by the body resisting angular acceleration.
Length of Primary Member - (Measured in Meter) - Length of Primary Member can be defined as the measurement of primary element in length.

STEP 1: Convert Input(s) to Base Unit

Collapse Prevention Level: 95.29 --> No Conversion Required
Moment of Inertia of Primary Member: 85 Millimeter⁴ per Millimeter --> 8.5E-08 Meter⁴ per Meter (Check conversion here)
Length of Primary Member: 1.5 Meter --> 1.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_s = (C_p*10^7*I_p)/(32*L_p^4) --> (95.29*10^7*8.5E-08)/(32*1.5^4)

Evaluating ... ...

L_s = 0.499978395061728

STEP 3: Convert Result to Output's Unit

0.499978395061728 Meter --> No Conversion Required

FINAL ANSWER

0.499978395061728 ≈ 0.499978 Meter <-- Length of Secondary Member
