Length of Secondary Member given Capacity Spectrum Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Secondary Member = (Capacity Spectrum*10^7*Moment of Inertia of Secondary Member/(32*Spacing of Secondary Members))^(1/4)
L_s = (C_s*10^7*I_s/(32*S))^(1/4)
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.
Capacity Spectrum - Capacity Spectrum can be defined as the capacity curve transformed from shear force vs. roof displacement coordinates into spectral acceleration vs. spectral displacement coordinates.
Moment of Inertia of Secondary Member - (Measured in Meter⁴ per Meter) - Moment of Inertia of Secondary Member can be described as the quantity expressed by the body resisting angular acceleration.
Spacing of Secondary Members - (Measured in Meter) - Spacing of Secondary Members can be described as the space in between the secondary members.

STEP 1: Convert Input(s) to Base Unit

Capacity Spectrum: 5.55 --> No Conversion Required
Moment of Inertia of Secondary Member: 90 Millimeter⁴ per Millimeter --> 9E-08 Meter⁴ per Meter (Check conversion here)
Spacing of Secondary Members: 2.5 Meter --> 2.5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_s = (C_s*10^7*I_s/(32*S))^(1/4) --> (5.55*10^7*9E-08/(32*2.5))^(1/4)

Evaluating ... ...

L_s = 0.499874953097637

STEP 3: Convert Result to Output's Unit

0.499874953097637 Meter --> No Conversion Required

FINAL ANSWER

0.499874953097637 ≈ 0.499875 Meter <-- Length of Secondary Member
