A new module: Post-tensioned concrete slabs for buildings has been included in the 2013.j version of CYPECAD, which has been created to design the passive reinforcement of post-tensioned slabs before calculating the forces of the post-tensioned tendons (bonded or unbonded) and whose properties have been introduced by program users.
Post-tensioned technology has different degrees of acceptance in many countries. CYPE has designed this module given the increasing demand of CYPECAD users to have a tool which can design post-tensioned concrete slabs.
The Post-tensioned concrete slabs for buildings module allows users to introduce the path of the tendons, their definition, the post-tensioned forces and percentage loss. The program generates a post-tensioned loadcase in which the deviation loads produced by the path of the tendons are introduced. During the slab reinforcement design stage, and if the tendons have been defined as bonded, if there is any capacity excess or shortage regarding the contribution of the active reinforcement, it will be taken into account to establish the passive reinforcement.
