15 Columns & Beams  columns - are vertical support members designed to carry loads from the floors above down to the foundation  reinforced with reinforcing steel  shown on drawings on a grid system of numbers and letters  specified on a column schedule  columns - are vertical support members designed to carry loads from the floors above down to the foundation  reinforced with reinforcing steel  shown on drawings on a grid system of numbers and letters  specified on a column schedule Unit 13 pages 132 - 133 Unit 13 pages 132 - 133 columns

16 Columns Unit 13 page 133 Figure 13 - 7 Unit 13 page 133 Figure 13 - 7

17 Column Schedules  identify the size and shape of column  number, size, & location of bars  size & spacing of ties  identify the size and shape of column  number, size, & location of bars  size & spacing of ties

18 Columns typical centerline layout C D 1 23 centerlines

19 Column Schedules C1 C2 C3 D1 D2 D3 C1 C2 C3 D1 D2 D3 Column # size rebar 8 - #9 6 - #7 8 - #9 6 - #7 #3 @ 4” ties 24” 20” 24” 20”

20 Splicing Reinforcement  splicing is required to transfer the stresses through the reinforcing steel  accomplished by overlapping the bars by a number of times the size of the bars  splicing is required to transfer the stresses through the reinforcing steel  accomplished by overlapping the bars by a number of times the size of the bars

26 Structural Steel  structural steel refers a buildings constructed from structural steel shapes wide flange beams - columns I-beams - beams angles - brick ledges pipes - columns, handrail tubes - columns “C” channels tees  structural steel refers a buildings constructed from structural steel shapes wide flange beams - columns I-beams - beams angles - brick ledges pipes - columns, handrail tubes - columns “C” channels tees Unit 13 page 134 Unit 13 page 134

27 Structural Steel  loads are designed so floor loads are transferred to beams, beams to columns, and columns down to the foundation Unit 13 page 136 Unit 13 page 136 Figure 13 - 14
