This paper uses solutions based on robust finite element analysis to validate simpler approaches to modeling column reinforcing cages. Finally, design methods are recommended to help prevent future failures. 1. Introduction.
One construction operation that has seen several high-profile accidents in the last decade is the placement of rebar cages for large cast-in-place concrete columns. Iron workers have been severely injured or killed while climbing on column cages that have collapsed while in their temporary condition, i.e., supported by bracing or guy-cable systems.
Loads on Rebar Cages and Who Design them? Design reinforcement bars inside concrete elements to resist code permanent loadings. Specify bar reinforcement details (cover, spacing, and splice type). Pepare contract document (Drawing and Special Provisions) for the reinforced concrete elements.
Method Statement for Rebar Cage Assembly - CivilPaper

Installation Of Reinforcement Steel Bars For Footing, Strap …
After completion of main mesh for raft, column starter bars shall be provided as per setting out details. For columns, the steel cages shall be pre-fabricated. Columns shall be erected at locations by mobile crane if there are more number of columns to be erected in an area and when working platform is not available.
unbraced column cage. • Any design elements (dowels, flutes, etc.) or installation of bracing should be pre-fabricated before the cage is lifted/tripped to the vertical position. • Cages should be protected from damage or deformation on the ground so as to avoid the need for personnel to climb cages to correct damage or fabrication errors.

Rebar Cage Construction and Safety: Best Practices - ASCE Library
Rebar Cage Construction and Safety: Best Practices presents guidelines for the safe handling of steel reinforcing-bar (rebar) cages throughout the design, fabrication, and erection process. The focus is on rebar cages used for large, cast-in-place concrete columns in a variety of settings, including bridge piers, elevated highway sections, and ...
Make Rebar Cages On-site for Concrete Piers - Instructables
Make Rebar Cages On-site for Concrete Piers: So, you're pouring a reinforced concrete pier foundation. The "concrete" part is easy, but you're a bit stumped as to how you can accurately place the steel reinforcement to match the design... The pro's would just fabricate a …
The focus is on rebar cages used for large, cast-in-place concrete columns in a variety of settings, including bridge piers, elevated highway sections, and high-rise buildings. These cages are inherently unstable, usually held together by tie-wire alone.
