Except the superstructures impose a control on the displacement at the top of the piles, the type of piles with different torlerance against cracking also have requests on the top displacement. Generally, the RC piles have a lateral displacement limit of 1/4~1/2", while steel piles will...
Using the order of 10% of the pole height as the acceptable displacement, I think, has some limitation, especially for longer monopole. As known, for general multi-story residential building, the permissible inclination is merely about 6¡ë according to people¡¯s psychological tolerance capacity...
Based on a field survey of some bridges in Canada by Bulzuk et al., I have undertaken a pilot study on the top displacement control of piles in industrial mills and given the criteria as follows:
a)when Sv<50mm and Sh<25mm , the displacements almost have no harm to upper framework, in which Sv...
