Model Stair Stringers in Tekla

I have found this the best way. It's very similar to the way I would do it in 2D c

1) Draw in grids as shown plus on plan for outside of stringers.2) Set x.y.z to their standard direction. Pick FLT10*200 set ends offset to -200 100 and right, front, froOn elevation draw in flat from point A to B. Move stringer up by 12 mm3) Check position in plan. I like to put the st ringers on the inside of the grid lines.4) Trim top of stringer back 10 mm with vertical cut line.5) Apply con 103 fin plate to top. Remember you have to play about to get it flushwith top of pfc. Put fin plate to inside of stringer. Line cut stringer flush with top of pfc.6) Cut 2 planes with line cut at base. Insert flat bar column. Do a con.1042 to put base on flat column.Explode base con. Remove column and weld plate to stringer. No need to do this Tekla have just advisethat con 1038 will do this ie put a base plate on stringer.7) Mirror stringer with base plate to other grid line. One can now draw in the treads.8) Next I intend to draw in one 65x6 flat bar end, cut chamfer & bolt group to stringer.

9) draw in front 30x5 nosing. Call this the main part by welding 65x6 end plate to it.10) Make this into Custom Component - Detail so I can use on any job. Export to firm folder.11) I 'll explode then mirror 65x6 to other stringer. Adjust length of nosing flat and copy backwards.12) The nosing flat wouldn't attach to custom component. As the size and length changes it can be putin for each job. uel no. is g3.uel and it's in my firm folder after I exported it. After you click exportit goes to the current model folder and one has type in g3.

The above sketch is taken from drawing ACW_01 Vietnam job. Treads are 275 mm wide 30x5 flat pitch

Open Treads from plain plate, durbar and perforated plate.

Go to profile catalogue>others pick BLZ insert these values BLZ280*100*5 this is assuming plate is 5 mOnce this is positioned correctly between stringers apply connection 116 with 50*50*6 rsa to both sidesMake sure the RSA Is symmetrical about centre of 280 mm size. Put a bit of transparency to the plate ifperforated. Go to elevation on stringer and make sure the view depths catch both stringers. Copy treadsend angles by going, riser and number of treads. Put a note on GA and detail drawings to say it's perfodurbar and the job is done. The screenshot is not quite correct as the leg depth of the front and back shinstruction above.
