All connections to the columns are considered to be "simple" connections—no moment transfer from beam/girder to column has been considered ! Normal weight concrete unit weight used in the designs is 145 pcf; lightweight concrete unit weight used in the designs is 110 pcf ! A maximum 40 psf roof live load has been considered for all column designs ! 35 ksi steel yield has been used for pipe columns ! 46 ksi steel yield has been used for hollow structural section columns ! 50 ksi steel yield has been used for rolled wide flange columns ! Only square hollow structural sections have been used in the tabulated dimensions ! Actual dimensions have been tabulated. The involvement of a qualified structural engineer shall deter- mine actual pipe, hollow structural section, or rolled wide flange section designation required for any specific project and loading condition.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
