Trang 4PRINCIPLES (6):
1) TRANSPORATION OF STRUCTURE ELEMENTS
1 Strenth of element must obtain that for moving For concrete one, strength must having at least 70% of R28
2 Element situation during moving should be similar to that at working condition(just to avoid stresses occurred different as disigned)

3 Bending elements must be chocked by using wooden pieces following designedpositions (hook position)
Trang 7PRINCIPLES (6):
4 When members laid on each other, supported (chocked) points should be on a vertical direction

5 When a long member is laid on 2 rail carriages, it should be supported on 2 different points, so the carriages can be rotated during transportation
PRINCIPLES (6):
Support point – rotation point
Trang 96 Length of structure member should be fit on truck, so it could be passed at corner ofstreets or roads.
