My dad's house was built in 1977 and it is a split entry brick house. It seems like a pretty stirdy house but there is no bridging between the floor joists. The joists are a little longer than that of other homes I have seen. Why is there no bridging here? Did the builder take a short cut or is there no need for it. Thanks.

Building codes vary, but most state that 2x6 floor joists do not require bridging. 2x8's and larger do. Perhaps this is the answer.

While I agree with the different time different code statement. You may still want to add solid blocking if you notice a bounce in the flooring. If you want to support the longer span and stiffen the floor even more, add a intermittent support beam in the middle of the span. This will make a major difference in an older house that will most likely not have bridging and have joist that are undersized and spaced further apart compared to today's building codes.

Different times different codes. For a house going on to be 30 years old and it has not been a problem I would say it is fine. If there was a problem it would have showed up a long time ago.

Bridging in general keeps things aligned, there is only a small amount of stability from bridging, blocking is where you gain lateral strenth and stability. They started blocking in the late 70s.

DONT KNOW YOUR CODES. BRIDGING KEEPS THE FLOOR JOISTS FROM TWISTING AND USUALLY THE LENGTH OF THE RAFTER DICTATES IF NEEDED.
