Hi all,
In "AASHTO LRFD 2012, Bridge Design Specifications 6th", there is rule for splice in column of seismic zone 4 as below.
'clause 5.10.11.4.1f - Splices
The spacing of the transverse reinforcement over the length of the splice shall not exceed 4.0 in. or one-quarter of the minimum member...
Thanks IDS, I got your point.
Dear, hokie66
The reinforcing steel is consist of total 3 layers.
1st(As'1) and 2nd(As'2) is top layer and each area is 3216,
3rd(As) is bottom layer and area is 3216.
Thus, total reinforcing steel area is 3216*3 = 9648mm2.
Thanks for your attention.
I have been performed a analysis of well foundations by shell elements.
And it is a result from vertical wall of well foundations.
Thus, sections are subjected high tensile force locally.
Hello all,
I have some doubt a P-M interaction diagram of concrete section.
I got a result as attached figure.
I think "It's OK", however any others told "It's NG".
I think it is OK, because Mr > phi Mn.
Any others told design force is not placed inside P-M line, because it's NG.
I want to...
