https://communities.bentley.com/products/bridge_design___engineering/f/bridgemaster-lars-leap-openbridge-rm-forum/123873/prestressing-tendons-in-leap-bridge-concreteIs it possible to model a prestessed beam using two different sizes of strands. My top flange has 0.5&quot; tendons pulled to 2000 lbs. However, the main reinforcing strands in the beam are 0.6&quot; 270K LL. Is there any way to accurately model a cross sectionen-USTelligent Community 12https://communities.bentley.com/thread/379549?ContentTypeID=1Mon, 15 Aug 2016 12:26:56 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:c9e5e3fb-53dd-4ae0-996d-8cafd3b3c4fakn238lzTo model the top strands you have to use the 0.6&quot; 270K LL and back-calculate the Pull % that is specified on the Beam stab under Strand Pattern-&gt;Debond/Pull%. Keep in mind that this pull % may be overwritten if you change anything about your strand pattern, but working with CONSPAN you should be used to having your patterns wiped out every time you change anything, shouldn&#39;t you? :-)<div style="clear:both;"></div>https://communities.bentley.com/thread/376118?ContentTypeID=1Tue, 19 Jul 2016 07:00:11 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:183e2865-3df3-4706-8f76-ff999296548dVinay mysoreCurrently it is not possible to model prestress beam using two different sizes of strands.<div style="clear:both;"></div>
