When u r using Google map for search any unknown location & estimate the time for location for the perticular location,then I think u donot use this process manually,, & Staad pro is just like that....b4 create any structure often we calculate the Steel consumption,cost and 3D rendering/realistic view , especially the probability of load over the structure,as the structure can consume its own load for the perticular soil stability & also calculate the probable section property or size of beam column,slab, outer wall and inerwall as per the load.forcthis total operation d manual process......oh its's unthinkable. So b cool and watch the video minutely for any queries u can ask me questions. It's all about technology,,,if there any automatic method for any process then why whould u want to learn the manual process,,u can learn this process from the Site Engineer.,,, during the erection of spiral staircase....ok dear friend stay tuned...

Please elaborate more about how reinforcement should be applied i want to learn about how to interpret the output file for the design of staircases....

Please attach reinforcement details

would you please make a tutorial of designing it manually?
