[The Six Million Dollar Man] Wouldn't Steve Austin's spine collapse if his bionic arm picked up something too heavy for it?

The simplest explaination is that while Austin didn't need a full body replacement (obviously beyond 1970s bionic technology), his skeleton and connective tissues were enhanced.  His spine, hips, shoulders, and likely ribcage are all lined with a titanium alloy to strengthen their resistance.  His connective tissues in some places are supplemented by titanium filaments.  His spinal discs were replaced by an advanced foam rubber.
