[单项选择]Quake Engineering:
Looking at the Turkish Earthquake Damage
Despite the size of the devastating quake that ripped through Turkey, American structural engineers say there was something that might have alleviated the damage and saved lives. These images of the devastation in Turkey confirm what seismic engineers already know: that a powerful earthquake has an ally in a weak building. Jim Malley of Degenkolb Engineers, "This is the most common form of multi-story building In Turkey. It’s what we call a concrete frame." Structural engineer Jim Malley studied damaged buildings in Turkey in 1992 after a 6.8 (Richter Scale)quake left more than 600 dead. Jim Malley says, "These are very heavy buildings and it’s not uncommon for them to collapse In earthquakes because of the extra mass. The risk of building collapse increases when the first floor is a shop and glass windows replace brick walls. Undoubtedly, there was a glass store fr
