Question

Detailing Concrate Reu n belbw is a larger-scale elevation view of the left end bf the ubus concrete beam shown in Figure 13.29 of the text. The structural plans call for a 10"-wide by 18"-deep (254 by 460 mm) beam with two #9 top bars and two #8 bottom bars. Fifteen #3 U- stirrups ahe required at alspacing of 7" (178 mm). 1. Make an accurately scaled drawing of the reinforcing bars in the beam, including top bars, bottom bars, and stirrups, drawing them as if the concrete Columnwere transparent. Give critical dimensions of any hooks. Do not show column reinforcing or bar deformations Beam 112-1'(18) ale: ฯ square-2"(50mm) 2. On the cross section to the left, draw accurately to scale the top bars. bottom bars, and U-stirrups for this beiam. No dimerisions are required. The hooks on the stirrups should face the cehter of the beam section. 3. The simply supported beam whose end is shown in elevation below has three #7 bottom bars with hooked ends and #3 stirrups at the same spacing5as those in part 1 of this exercise. Draw the reinforcing in the beam and give critical dimensions of ary hooks. Do not show column reinforcing Cross Section of Beam L : Beam lurmn 08 121' (18) Scale: q 5o m
