As an example, ACI 318 specifies either Type 1 (125% Fy) or Type 2 (125% Fy and 100% Fu) performance criteria. [ 33 ] For concrete structures designed with ductility in mind, it is recommended that the mechanical connections are also capable of failing in a ductile manner, typically known in the reinforcing steel industry as achieving "bar-break".
The ACI codebook puts an upward limit on the spacing between ties. ACI Code 7.10.5: Vertical spacing of ties shall not exceed 16 longitudinal bar diameters, 48 tie bar or wire diameters, or least dimension of the compression member. If the ties are spaced too far apart, the column will experience shearfailure and barrel in between the ties. [4]
The ACI 318 Building Code Requirements for Structural Concrete uses Limit State design. The ANSI/ AISC 360 Specification for Structural Steel Buildings , the ANSI/ AISI S-100 North American Specification for the Design of Cold Formed Steel Structural Members , and The Aluminum Association 's Aluminum Design Manual contain two methods of design ...
Fiber-reinforced concrete or fibre-reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented.
