    Post-tensioning only portions of a structure

    Hello, I just want to know what is your opinion on PTing only portions of a structure. I only need to really PT a cantilevered portion of my structure (the other slab and beams do not really need PT). I hear from others that you should PT the entire structure due to shrinking and cracking...

    Banded Tendons in One-Way Slab

    Can you put banded tendons in a one-way slab or is it normally just distributed tendons in one direction for a one-way slab. In a two way slab it is normally distributed tendons in one direction and banded tendons in the perpendicular direction, right?

    ADAPT PT design philosophy

    Hello, I need help designing a PT two-way beam-slab system. 1) What is the design philosophy of ADAPT PT? Could I design the T-beams (input beam and appropriate tributary width) and use the appropriate number of tendons designated in the execute/recycle loop and place all those tendons only...

    Concrete Shear Wall Design

    Hello, I'm a new structural Engineer. For those of you familiar with ETABS v9, I need help designing a concrete shear wall (general). 1) Let's say I have a 2 bay shear wall going up 6 stories. I can label the left piers P1 and the right piers P2, or I can label the piers P1-P12, or label all...
