Normally in so-called full roll cage these issues are addressed.
Falling just short of a full roll cage are rocker panel reinforcements that are often triangular in shape from foot-well zone going upward to middle part of B-pillar.
When a car "folds in half" it is the area around the doors that "give it up" and allow the occupants to be crushed. Stiffing this area stiffens the chassis considerable but comes at the cost of ease of entry and exit.

Reminds me of the BMW i8 with its quite high door sills. Not so hard to slide inside, a PITA to get out.
