Rebar in tension or compression
Webbare the APRs defined in the d–r coordinate system. They express the effect of tension on the compressive strain and the effect of compression on the tensile strain, respectively. [N] is the matrix containing the APRs. (6) According to the above definition, the following are the expressions of the APRs in terms of the strain components. (7) WebbLap splices of #14 and #18 bars should not be used, except in compression only to #11 and smaller bars. Lap splices of bundled bars should be based on the lap splice length …
