Select the incorrect statement about space frames A. Space frames are different from many long span structures because of their redundancy. B. Top and bottom grids of a space frame can run in different directions, but they usually are oriented the same way. C. Regularly spaced supports with overhangs are more efficient than supports located at the perimeter of a space frame structure. D. Space frames are economical structures because their many connections can be prefabricated. Click here for answer 9. A dome is a very stiff structure for which of the following reasons? A. Strain is small due to all stresses being in compression or tension. B. The boundary of a dome is prevented from moving because of its circular shape. C.
