One picture from the site you quote but three from your own website. Are all these large cut and pastes necessary? Are you bored or running out of ideas? Or desperate?
You announce:
Some photos of fire damage to steel framed structures:
But what you forgot to add is that the pictures were taken in 1906. Before there was a standard for structural steel. The photographs you've presented are from the earthquake in San Francisco in 1906 where fires after the earthquake did a lot more damage than the earthquake. I think it was fractured gas mains initiating the fires that left about 75% of the population destitute; if I remember right. Desperate measures were taken by the army to arrest the firestorm, they tried explosives to blow up the areas around the fires to create fire-breaks; they even tried an artillery barrage for the same end. Most of the efforts to mitigate the fire only served to increase the damage.
Ironically perhaps, 1906 was a bit of a landmark year for structural steel.

Have a look. It starts on the section, '
steel before 1906' and the next section is '
steel after 1906'. Your choice of year is quite apposite to the discussion, if a little out of date. Why are you posting great big pictures of 100-year-old, non-standardized, cheap-and-nasty steel used in the for-mafia-profit construction of San Francisco - what are you trying to prove? What a shelled, exploded, firestorm-ridden late nineteenth century city looks like? Where is the comparison to wtc's 1, 2 and not forgetting.....7?
Here's a secret: standards have changed a little since then. When I say standards I mean Standards. They even have their own capital letter; it's a Proper Noun! Things have moved on a bit, honestly. They'd moved on quite a bit by the mid-sixties. Changes are made to building regs (codes) on a near daily basis where I come from; certainly
since 1906, when the first standard for steel used in construction was created.
What's next? More big pictures and/or copy and pastes from your own sites? Oh good.
