2016 PTI Convention Long Beach, California

Anchorage Zone Design: “The spring energy stored in four 19-0.6” strand tendons of 650 ft. of length is theoretically sufficient to launch an HS 20-44 truck over a seven-story building”. • These large forces are applied to the anchorage that in turn transfer high compressive and tensile stresses to the anchorage zone.

Shear

Where applied shear stresses are higher, one has to check against the maximum allowable shear stress at the maximum strut angle of θ = 45º (e.g. 5.28 MPa for a C30/37 concrete when cot θ = 1.0) and where necessary determine the actual intermediate strut angle, θ. It is not usual for a slab to contain shear reinforcement.

Pre Stressed Concrete

Prestressed Concrete VII. Applying external load: This method entails prestressing an arch slab or arch rib spanning between two unyielding abutments. A loaded column can be regarded as being prestressed against stresses due to bending moments, as also can an arch if it is uniformly compressed by a large dead load. VIII. Usage and Advantages of ...
