The Importance Factor (I) for wind loads, as specified in ASCE 7-05, varies based on the occupancy category of the structure. It typically ranges from 0.87 for buildings in Category I (low hazard, such as agricultural buildings) to 1.15 for Category IV (essential facilities, like emergency services). This factor adjusts the design wind loads to account for the potential consequences of failure, ensuring that more critical structures are designed to withstand greater wind forces.
Importance Factor should be specified by engineer of record for the structure. If you refer to ASCE 7-05 you can find the different Importance Factors based on occupancy type / intent. There are three different importance factors: wind, snow and seismic.
Present value annuity factor calculates the current value of future cash flows. The present value factor is used to describe only the current cash flows.

i think you should understand what is live load and cycling loading actually, live load Live loads are usually unstable or moving loads. Live loads, or imposed loads, are temporary, of short duration, or moving.so as per my understanding, fatique is actually cause by these moving/dynamic loadings( a loads which is not stable and moving i-e a sand bag on wheel borrow is moving over the structure). Fatiguefailure is caused by fluctuating load. Fluctuating loadis one in which theloadvalue chages from a highest value to zer then to negative extreme
The present value factor is the exponent of the future value factor. this is the relationship between Present Value and Future Value.
Present value annuity factor calculates the current value of future cash flows. The present value factor is used to describe only the current cash flows.

Oh honey, let me break it down for you. A un-factored load is like a wild horse running free, it's the load acting on a structure without any safety factors applied. Now, a factored load is when we slap on those safety factors to account for uncertainties and make sure that structure can handle whatever life throws at it. So, in a nutshell, un-factored load is the raw deal, while factored load is the safety-net version.

For residential load, power-factor improvement is irrelevant as it will make no difference to the quantity of energy consumed and, therefore, the electricity bill. For industrial/commercial consumers, poor power factor results in additional charges over and above those for the amount of energy consumed. The electricity supplier will specify a value below which these additional charges will be imposed, so it's in the interests of the consumer to ensure the power factor of their loads doesn't fall below that agreed value.
Power factor is the cosine of the angle between current and voltage. Most of the loads are inductive.In inductive loads current always lag the supply voltage.In unity power factor condition the current and the supply are in the same phase. Since, P=V*I*cos(angle between V & I) Now for a constant power as power factor changes i.e: decreases, to keep power demand constant current has to increase as your voltage is constant.In this way the current increases due to increase in copper losses (I*I*R),voltage drops (I*R) and to keep this voltage constant more reactive power is required. KW = KVA * cos(angle between V & I).....so as the power factor is getting lower,the actual output we obtained from the transformer will be lower than the desired output for the particular value of voltage and current in that circuit.That is why in industries have given much more importance for power factor improvement.

That is the correct spelling of "important" (having value, crucial, or essential).
