Analysis and Design of Vertical Post-Tensioned Precast Shear Wall

Abstract

This study aims to provide analysis and design of Vertical-Post-tensioned Precast Shear Wall as per IS 1343:2012. Instead of using conventional cast-in-situ Shear Walls, use of precast shear wall using post-tensioned tendons for flexural reinforcement observed only small amount of damage to the concrete material. This research focuses on the use of unbonded post-tensioning tendons for wall to wall connection in precast shear wall across the horizontal joint over the portion of its length. For this purpose a commercial (G+4) storied building with shear walls modelled in ETABS2016 to analyse the structure and to found the load coming on shear walls. Design of Precast Shear walls using post-tensioning tendons are done manually for each precast walls. The behaviour of vertical post-tensioned precast shear wall is captured by analysing the precast shear wall in SAP2000 software.
