In all the engineering offices i have worked. When looking at an R.C. cross-section with partially developed reinforcement, the general approach has been to reduce the bar area by multiplying the area of the bar by the percentage of the bar development. However, the phi factor is not usually...
When designing a column to AS3600, I find it a bit unclear exactly how PhiNu should be calculated. Figure C5.6.3 in the commentary shows an interaction diagram where a straight line is drawn from 0,0 and through M*,N*. PhiNu is then taken at the point where this line intersects the curve. But it...
