The minimum number of longitudinal bars in a column based on the type of transverse reinforcement is given in ACI 318 Section 10.7.3.1 (Table 1).Where longitudinal bars are in a circular arrangement,the orientation of the bars has an impact on the moment strength of a column where less than 8 longitudinal bars are provided; this must be considered in the design.STRUCTURE magazine Design of Reinforced Concrete Illustrated in Figure 1 is a diaphragm with an LFRS consisting of structural walls and collector elements.The lateral force is transferred through the web of the diaphragm to the walls,which act as supports for the diaphragm.Because the wall on the left does not extend the full depth of the diaphragm,collector elements are needed to collect the shear from the diaphragm and toRelated searches for placing reinforcing steel concrete consconcrete reinforcing steelconcrete reinforcing steel specificationssteel reinforcing rod for concreteconcrete reinforcing steel meshconcrete reinforcing steel instituteconcrete reinforcing productsreinforcing concrete with rebarconcrete reinforcing meshSome results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456Next
