In the tendon prestress load window, when inputing the jacking stress value, should the value be entered for begin and end, or just begin? Say i have a jacking stress of 202.5 ksi, should i enter that for begin and end or would that double the jacking stress? (I watched a midas tutorial that entered the stress at begin and end, but saw in a midas pdf tutorial where it was only entered for begin, and end was zero.Not all barrier cables are rated for vehicular impact and are for pedestrian protection only. How do I turn on/off the display of the strands in model view?Ĥ. I created the beams using the prestressed composite bridge wizard, where I inputted the strand pattern and debonding data, but I can't seem to be able to get to that information once the model has been created.is there a way to view or modify the strand patteren/debonding outside of the wizard?ģ. box beside Total tendon area and the window comes up with Strand diameter and number of strands, should these be entered for one strand (say 0.5" diameter, and 1) or should this be the strand diameter and the number of strands (say 0.5" diameter, and 88)?Ģ. In the tendon properties window, when i click on the.
