    Regarding anchor bolt design for pier foundation.

    Thanks for all your comments. @delagina, thanks for the reference, i went through the reference and it seems like if provided edge distance is > 6do then side-face blowout can be prevented. In my case, the edge distance is exactly equal to 6in (6X1" dia), is it safe to assume side face blowout...

    Regarding unity bending code check?

    Thank you very much again Josh. I am applying area wind load to my tower model. I used open structure option and defined leg members as columns, X Diagonals as VBraces, Horizontal struts as HBraces. Is that the right way of defining the section types? Because, as you said, when i use area load...

    Regarding unity bending code check?

    Thanks for the reply JoshPlum. Actually i was using AISC 360-05 code, but i am working with RISA 3D Version 9.0.1. This version might be the reason. Also, regarding the calculation of compressive axial stress. how does RISA handle KL/r ratios? I went through the calculations for typical member...

    Regarding unity bending code check?

    I am modeling a tower using hot rolled single angle members, the members are drawn from center to center without considering any offsets. Modeled leg members as beam type and X braces as either HBrace or VBrace type members. Given design list as single angle for all the members. Also, considered...
