A Practical Guide to Design and Installation

Helical piles have risen from being merely an interesting
alternative for special cases to a frequently requested, more
widely accepted deep foundation adopted into the 2009 International
Building Code. The first alternative to manufacturer-produced
manuals, Howard Perko's Helical Piles: A Practical Guide to
Design and Installation answers the industry's need for an
unbiased and universally applicable text dedicated to the design
and installation of helical piles, helical piers, screw piles, and
torque anchors.

Fully compliant with ICC-Evaluation Services, Inc.,
Acceptance Criteria for Helical Foundation Systems and
Devices (AC358), this comprehensive reference guides
construction professionals to manufactured helical pile systems and
technology, providing objective insights into the benefits of
helical pile foundations over driven or cast foundation systems,
and recommending applications where appropriate. After introducing
the reader to the basic features, terminology, history, and modern
applications of helical pile technology, chapters discuss:

• 
  

  Installation and basic geotechnics

  
  


• 
  

  Bearing and pullout capacity

  
  


• 
  

  Capacity verification through torque

  
  


• 
  

  Axial load testing, reliability, and sizing

  
  


• 
  

  Expansive soil and lateral load resistance

  
  


• 
  

  Corrosion and life expectancy

  
  


• 
  

  Foundation, earth retention, and underpinning systems

  
  


• 
  

  Foundation economics

  
  


• 
  

  Select proprietary systems

  
  


• 
  

  IBC and NYC Building codes

  
  

Covering such issues of concern as environmental sustainability,
Helical Piles provides contractors and engineers as well as
students in civil engineering with a practical, real-world guide to
the design and installation of helical piles.
