Importance Factor using Roof Type Solution

STEP 0: Pre-Calculation Summary
Formula Used
Importance Factor for End Use = Roof Snow Load/(Roof Type*Ground Snow Load)
I = Pf/(C*Pg)
This formula uses 4 Variables
Variables Used
Importance Factor for End Use - Importance Factor for End Use is the factor whose value lies in range 0.8 to 1.2.
Roof Snow Load - (Measured in Pascal) - Roof Snow Load is the downward force on a building's roof by the weight of accumulated snow and ice.
Roof Type - Roof Type reflects the type of the roof.
Ground Snow Load - (Measured in Pascal) - Ground Snow Load is used in the determination of the design roof snow load of a site.
STEP 1: Convert Input(s) to Base Unit
Roof Snow Load: 12 Pounds per Square Foot --> 574.563107758693 Pascal (Check conversion here)
Roof Type: 3 --> No Conversion Required
Ground Snow Load: 18 Pounds per Square Foot --> 861.84466163804 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
I = Pf/(C*Pg) --> 574.563107758693/(3*861.84466163804)
Evaluating ... ...
I = 0.222222222222222
STEP 3: Convert Result to Output's Unit
0.222222222222222 --> No Conversion Required
FINAL ANSWER
0.222222222222222 0.222222 <-- Importance Factor for End Use
(Calculation completed in 00.004 seconds)

Importance Factor for End Use using Roof Snow Load
Go Importance Factor for End Use = Roof Snow Load/(0.7*Wind Exposure Factor*Thermal Effects Factor*Ground Snow Load)
Thermal Effects factor given Roof Snow Load
Go Thermal Effects Factor = Roof Snow Load/(0.7*Wind Exposure Factor*Importance Factor for End Use*Ground Snow Load)
Wind Exposure Factor given Roof Snow Load
Go Wind Exposure Factor = Roof Snow Load/(0.7*Thermal Effects Factor*Importance Factor for End Use*Ground Snow Load)
Ground Snow Load given Roof Snow Load
Go Ground Snow Load = Roof Snow Load/(0.7*Wind Exposure Factor*Thermal Effects Factor*Importance Factor for End Use)
Roof Snow Load
Go Roof Snow Load = 0.7*Wind Exposure Factor*Thermal Effects Factor*Importance Factor for End Use*Ground Snow Load
Importance Factor using Roof Type
Go Importance Factor for End Use = Roof Snow Load/(Roof Type*Ground Snow Load)
Ground Snow Load using Roof Type
Go Ground Snow Load = Roof Snow Load/(Roof Type*Importance Factor for End Use)
Roof Snow Load given Roof Type
Go Roof Snow Load = Importance Factor for End Use*Roof Type*Ground Snow Load

Importance Factor using Roof Type Formula

Importance Factor for End Use = Roof Snow Load/(Roof Type*Ground Snow Load)
I = Pf/(C*Pg)

What is Snow Load?

Snow load is the downward force on a building's roof by the weight of accumulated snow and ice. The roof or the entire structure can fail if the snow load exceeds the weight the building was designed to shoulder. Or if the building was poorly designed or constructed.

How to Calculate Importance Factor using Roof Type?

Importance Factor using Roof Type calculator uses Importance Factor for End Use = Roof Snow Load/(Roof Type*Ground Snow Load) to calculate the Importance Factor for End Use, The Importance Factor using Roof Type formula calculates the importance factor when we have a prior info of roof type along with roof snow load. Importance Factor for End Use is denoted by I symbol.

How to calculate Importance Factor using Roof Type using this online calculator? To use this online calculator for Importance Factor using Roof Type, enter Roof Snow Load (Pf), Roof Type (C) & Ground Snow Load (Pg) and hit the calculate button. Here is how the Importance Factor using Roof Type calculation can be explained with given input values -> 0.222222 = 574.563107758693/(3*861.84466163804).
