No. They do not wear out. What happens is they are made or installed poorly, or some other piece fails and allows the joists to get wet which then rots them out. That's why particle board is bad. It will absorb water like a sponge and rot any other wood pieces it touches.

Unless they are failed, you are just wasting money replacing things that are fine. Houses last hundreds of years without any replaced parts if they are well made and well maintained. The replaced parts they DO get are due to water or bugs usually.
