Fatigue is a mechanical degradation process caused by repeated loads, such as traffic loading or wind loads on a bridge, that results in irreversible damage in concrete structures. Many types of concrete elements are subjected to repeated loads, such as airport and roadway pavements, bridge girders, bridge decks, wind turbines, and prestressed concrete railroad ties. This document provides information that will benefit practicing engineers interested in the design or rehabilitation of concrete structures subjected to high-cycle fatigue—that is, stress cycles in which the material behavior remains within the elastic range. The effects of repeated loads on plain concrete, reinforcing materials, and reinforced concrete systems are discussed based on a summary of available literature. This report does not contain detailed design procedures but rather should be considered a general resource providing a comprehensive overview of fatigue issues in reinforced concrete structures.
Keywords:

Author(s)/Editor(s): R F. Warner; Stephen Foster; Andrew Kilpatrick; Rebecca Gravina| Format:PDF| Quality:Original preprint| Publisher: Pearson Australia| Year: 2022| pages: 669 | ISBN: ISBN: 9780655706397,9780655706403
The prime purpose of this new edition of Prestressed Concrete is to take account of important changes that have been made in the new edition of the Australian Standard for Concrete Structures, AS3600-2018 which appeared in 2018, and including Amendment 2 published in 2021.
Changes include modifications to the rectangular stress-block parameters for flexural strength calculations, modifications to the design clauses for shear and torsion, and changes in the safety coefficients for ultimate strength design which result in a slight reduction in the overall safety margins for design.
First published in 1979 by UNSW civil and structural engineering academics Robert F Warner and Ken Faulkes, Prestressed Concrete made a significant contribution to the global body of civil engineering knowledge and practice. It rapidly became a classic text for generations of students and throughout its subsequent editions has been extensively rewritten to take account of modern developments in the theory and practice of prestressed concrete construction.

Anyone recommends a good reference that could be used to design tangent pile walls?.
I am involved in 10 ft deep excavation in which the best option will be to use tangent piles to support an adjacent house that was built right on the property boundary.
CSiDetail creates a detailed model of the structure, based on its analysis model and the design process carried out in ETABS and SAFE. It automatically generates views and drawings that can be used as the basis for preparing final engineering drawings, as well as BIM files for use in BIM tools. Detailing can be carried out both for concrete and steel buildings.
