Current building codes don't take into account structural damage that could occur when two or more natural disasters such as earthquakes and hurricanes hit the same area, according to a National Institute of Standards and Technology report published in the Journal of Structural Engineering. The codes take into account individual disasters and do not require that structures be designed for both wind and seismic loads simultaneously. Buildings tailored to meet code requirements in these double-jeopardy areas "do not necessarily achieve the level of safety implied," the researchers write.
