Finite Element Analysis of Post Tensioned I-Beam with Web Openings

Abstract:

Construction of pre-stressed concrete (PSC) structures is becoming a common practice in various parts of the world, because of its better stability, serviceability, economy, aesthetic appearance and structural efficiency. Post tensioning is a method of reinforcing concrete or other materials with high strength steel strands or bars, typically referred to as tendons. The provision of large openings in pre-stressed concrete beams is necessary to accommodate utility services in residential, commercial, and industrial buildings. A post tensioned I-beam is analyzed by using ANSYS software and the deformation and stress pattern of beam is studied for different parametric conditions by changing the position of opening and different shapes of openings.
