How to Evaluate Collapse Prevention Level?

Collapse Prevention Level evaluator uses Collapse Prevention Level = (32*Length of Primary Member^4*Length of Secondary Member)/(10^7*Moment of Inertia of Primary Member) to evaluate the Collapse Prevention Level, The Collapse Prevention Level formula is defined as the building performance level consisting of the structural collapse prevention level with no consideration of nonstructural vulnerabilities, except that parapets and heavy appendages are rehabilitated. Collapse Prevention Level is denoted by Cp symbol.

How to evaluate Collapse Prevention Level using this online evaluator? To use this online evaluator for Collapse Prevention Level, enter Length of Primary Member (Lp), Length of Secondary Member (Ls) & Moment of Inertia of Primary Member (Ip) and hit the calculate button.

FAQs on Collapse Prevention Level

What is the formula to find Collapse Prevention Level?
The formula of Collapse Prevention Level is expressed as Collapse Prevention Level = (32*Length of Primary Member^4*Length of Secondary Member)/(10^7*Moment of Inertia of Primary Member). Here is an example- 95.29412 = (32*1.5^4*0.5)/(10^7*8.5E-08).
How to calculate Collapse Prevention Level?
With Length of Primary Member (Lp), Length of Secondary Member (Ls) & Moment of Inertia of Primary Member (Ip) we can find Collapse Prevention Level using the formula - Collapse Prevention Level = (32*Length of Primary Member^4*Length of Secondary Member)/(10^7*Moment of Inertia of Primary Member).
