ST7-1.40.35.6 Modelling Post Tensioned Concrete in Strand7
Given that Strand7 is a general purpose FEA package rather than a specialised prestressed concrete (PSC) design package, users may not be aware of the potential for Strand7 to analyse PSC structures. This document outlines one method for modelling a post-tensioned one-way slab (150mm thick) and transverse band beams (400mm deep) with discrete draped bonded tendons. In addition to self-weight and prestress, the slab will be subjected to a 1 kPa superimposed dead load and a 7.5 kPa live load.
