never thinking about it before,anyway nice question
iam not sure but if you used blockchain you can generate address and still recorded on your wallet and never expire,so the conclusion is no.
but actually i have simillar question i always generate new address on poloniex especially altcoin's address,if i give someone a address to send me some altcoin, and then they wait maybe 1 weeks before they sending me and then i generate new address before they send me,is my address still recorded like blockchain did or i'll lose it and what would be happen with my coin?

No bitcoin addeesses never expire ok you can use the same address again and again but it's advice to change address everytime which i don't know why
no, but i can see in the future, if the technology is changed and we need a new typo of private key, hashed in another form, it may become invalid at that point
but i'm sure the dev would say it long before it will happen

it is valid as long as you have the private key
Yes private key matters. No one is ready to share their private key unless for any other peculiar reasons. Bitcoins can be sent or revived with any old bitcoin address.
Some online services shows you a new address with a timer, this is because to identity your transaction with their hot wallet.
it is valid as long as you have the private key
Great question, no, Bitcoin addresses don't expire.
Yeah, people wonder about such incredible things. I wouldn't think about expiring address 
but now other people reading this topic will know better.Yes, to be really honest, I never thought about this as well. I guess this was just something that made common sense to me that it can't happen so I wasn't even worried about.
But yes OP, this was a pretty good and simple question! Now we are all sure!
Also, it should be worth noting that most of the time when you receive bitcoins on some wallets, the address will change... don't worry about that, the address you provided before for someone to pay you will still remain valid and payments will still end up in your wallet from the previous address.
suppose you give someone a btc addresses to send you bitcoin, and then they wait 8-12 weeks before sending you bitcoin to that address.
is the address still valid? It will still go to your wallet?

Bitcoin address does not expire it stays alive "forever"
But the other part is that you should always check that it is available in your wallet or account.
Because if you backup your wallet, and after that you made transaction, if your coins are moved to another address (from the same wallet) and after a time you want to restore your wallet with the old wallet backup you may loose your bitcoins as the new address generated will not show to your wallet which means you lost, i will find a thread about this story and will let you know. Basically it does not expire but it's all about if you can access it.
No. Losing your wallet is what gets you.
Depends on which wallet you are using. If you are using desktop clients like Core, Electrum, Multibit, where you generate your own address, they never expire if you have the private key in your wallet file.
If are using a shared web wallet where you do not have the private keys to the address, they may "expire". You never have control of the address, the web wallet site credit your balance with the amount they receive into the address. When they stop checking that address or when they drop the old private keys, your address "expires".

This may also be the case with some exchanges - they will give you a deposit address but since you don't own the private keys it's best to check that they are still using that same address for you to deposit.
Your own wallet addresses though will not expire. It's best to always keep your keys backed up safely.

i dont think that bitcoin addresses cant expire but i heard once that it is possible that the same bitcoin private keys might be generated by a really small chance

Great question, no, Bitcoin addresses don't expire.
Once they're created they never go anywhere. Just make sure to retain the private keys. If you're using a HD wallet like Mycelium and carry out subsequent transactions then new addresses will be created for each one, but if money is sent to the old address it'll still show up in your balance.
