It seems to me that the freeway columns in the San Francisco area are faulty. It seems that they are prone to falling down than in other areas of the state. Is it because the design of the freeways are faulty?

Remember, that the coulmns melted under the heat of the burning gasoline truck. Just imagine in a magitude 6 plus earthquake.

hardly. The kind of temperatures they were exposed to seriously effect the strength of the steel. The temps at which they were heated can not only cause cracking in concrete due to rapid expansion, but also can make the steel used greatly lower its yield point.
they would do much better against an earthquake than a fire like that.

Your impressions are faulty.
That portion of freeway was rebuilt from the 1989 Loma Prieta quake using a brand-new design should withstand even a 7.5 quake on the Richter scale.
The tanker truck produce a fireball of up to 3200 degrees Fahrenheit as well as sustained flame, plenty to melt steel rebar even encased in concrete. (Most steel melt at 2500 F)
So please take your mistaken impressions elsewhere.

No, theyre perfectly safe, but when a huge truck full of gasoline explodes nothing really is safe
