I have defined a series of shear walls using plates and would like to use Results Along Line feature to obtain the shear wall forces for one particular wall at a time. How can I do that ?
When you want to draw the cut line for a particular wall, ensure that you only have that wall in your view ( select the wall elements and go to View > View Selected Objects Only ). Change your view to a suitable elevation view so that you see the wall from the front. Now when defining the cut line, choose the option "Cut By Line" and draw the line from one edge of the wall to the other to define the local x for the line. Click above or below the line to define the local Y for the line. Your cut line will now cut only that particular wall and not any others lying in its vicinity. For better results, try to draw the line through the center of any row of plates and do NOT draw the line through the nodes of a plate mesh.
Although the procedure above mentions about walls but the same is applicable for cutting sections through slabs as well.
ALTHOUGH THIS WAS POSSIBLE IN OLDER VERSIONS OF v8i BUT IT IS NOT AVAILABLE ANYMORE IN MORE RECENT VERSIONS. THE RESULTS ALONG CUTLINE FEATURE HAS BEEN REVAMPED IN THE STAAD.PRO CONNECT EDITION AND ANYONE USING THE RESULTS ALONG LINE FEATURE SHOULD USE STAAD.PRO CONNECT EDITIION VERSION 22.02.xx.xx OR HIGHER.
