2021 ITA publication: shafts - definitions & classifications

2021 ITA publication: shafts - definitions & classifications

13 July 2021

The 26th ITA report has just been published!

The latest Working group (WG23 on Design and construction of shafts) that has been approved by the 2019 ITA General Assembly, has just published its first ITA report. 

Following the first WG 23 meeting in Naples, the need for defining common terms was raised and it was decided to prepare a document to explain and develop the correct terminology and nomenclature for shaft design and construction.  
It was also discussed that suitable classifications for shafts based on their geometry, application, ground conditions, and construction methods was needed for a more uniform understanding of design and construction implications. 
This document is prepared in response to the above mentioned needs and provides common definitions for relevant terms in addition to introducing different types of classification systems for shafts that can be implemented during design and construction of these structures. 
The document contains contributions of various individuals. Work has been coordinated by Siamak Hashemi (Animateur of WG 23) and Jamal Rostami. Tarcisio Celestino was the Tutor of WG 23.
