You draw segments with continuous condition like Makhzumi said. You can check your BMD and SFD and it will show you that as a continuous member. CSI programs (SAP and ETABS) do not analyze curved elements per se. Nevertheless, you can approximate a curved beam by using a series of straight segments. I mean, approximate an arc by using an open polygon. Be careful, if the lenght of the segments is shorter than their depht, concrete design will raise a shear overstress warning.

Hi, Share your experiences on the best structural design firms that you have found while working in Pakistan. It can provide insight to members on the board to: join, not to join, or look for opportunities in different firms. Listing pros and cons will help others. Thanks

here is the jpg of the cad drawing .i have one problem to draw the curved beam and secondly if u check in the drawing beams are at the edge of column so do i draw then in center in etabs or same as in the drawing ,if i take them in center of column will it effect the analysis?

I would not say anything about best structural design firms, but I would name the structural engineer, who impressed most: Rizwan Mirza. He runs the firm by the name of Rizwan Mirza Consulting Engineers, Lahore.

Waqar, please post an image of what are you modelling? Maybe, that can help understand the situation better. Thanks.
