PAGE 89 SYSTEMS DETERMINING INTERIOR COLUMN SIZES Determining the overall size for column enclosures is a function of the column dimensions as well as utility serv- ices which may be running vertically, immediately adjacent to the columns. Column sizes determined by the struc- tural engineer must account for gravity loads as well as lateral loads. Having a fairly accurate selection of a col- umn size during the planning and schematic design phases of a project can greatly assist the architectural and interior design teams. Preliminary column dimensions have been tabulated for buildings ranging from one story to six stories. Two dif- ferent commonly used floor live loadings have been tabulated. One roof live loading was selected to be used for each of the floor live loadings. The selection of a single roof live load was found to have a very minimal effect on the overall column size selection. The interior columns are assumed not to contribute to the lateral load resist- ing system for the building. The tables presented (see Table sets F, G and H) indicate representative interior col- umn dimensions for square and rectangular bay sizes ranging from 20 ft × 20 ft to 40 ft × 40 ft. Each set of tables represents a different floor construction type meeting a two-hour fire rated floor system.

    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.
