IES Virtual Classroom - PRESTRESS DESIGN FOR BUILDING STRUCTURES 1ST RUN - REGISTRATION CLOSED.

Synopsis

Prestressed buildings offer various advantages as compared to the conventional reinforced concrete design, including lighter structural weight, better crack resistance and more cost effectiveness. Prestress design with post-tensioning has been commonly adopted for cast in-situ building structures in Singapore due to the above advantageous.

This training course explains the design fundamental of the prestressed structures with post-tensioning. During the course, the structural behaviour of prestressed buildings and their benefits are highlighted. The economical range for prestressed structures and the typical range of the reinforcement and tendon quantity are studied.

In the second part, the course explains the steps of designing a post-tensioned structure. This starts with the member sizing and the analysis of the structures; followed by the design of the tendon prestressing force at service state as well as the ultimate capacity of the prestressed structure at ultimate state. The basic principles for the calculation of prestress losses are demonstrated in detail.

This course also explains the analysis approach and design requirements for prestressed flat slabs and the prestressed transfer plates.
