Structural design engineers normally completely ignore the presence of the steel decking, foregoing some of its benefits and ignoring potential problems, although sometimes they are making arbitrary decisions about the extent to which the steel decking might act as main tensile reinforcement in the direction of the sheeting ribs, in order to justify their designs.

With the development and general acceptance of reliable and efficient partial shear connection strength theory for composite slabs incorporating steel decks that develop strong mechanical resistance, it has been possible to develop a sound method for strength design of post-tensioned composite slabs, with Fielders’ KingFlor profiles leading to more efficient economical slab designs.

PT Plus – Moment Capacity Tables

Fielders’ world first research has lead to the development of “PT Plus”, a completely new set of design positive moment capacity tables to assist with the design of one-way, post-tensioned composite slabs incorporating Fielders’ KingFlor composite steel formwork profiles and bonded prestressing strands as tensile reinforcement in the slab bottom face.

Fielders are able to assist structural design engineers in incorporating a PT Plus solution to their project, thereby accessing potential savings by utilising the KingFlor’s contribution to the slab as main reinforcement.
