Composite Structure with PT

• PT is sometimes introduced in steel or composite design due to its excellent tensile capacity
• They are usually introduced at the members which experience high tensile stresses (e.g. bottom chord of a simply supported steel truss)
• The benefits of introducing PT at such structures are as follows:
- To reduce the overall steel sections required to satisfy the required tensile forces by replacing them with PT tendons which can be installed and stressed after the erection of the steel truss
- This will help to reduce the overall handling weight of the steel truss, which could greatly benefit the builder on site
• PT tendons could also be used to moderate the overall deflections of the composite structure
