Depth of Compression Zone

Post by ebaf65 »

Hi,

I need to calculate distance between the bar and neutral axis ( d-x) in a RC column.

How can I calculate Depth of compression zone? Which recorders I need to use?

Thanks.

You could use:
1. "recorder Element -file Element1.out -time -ele 1 section 2 deformation" which will give you axial-strain and curvature of the integration point 2 of the element 1. Then you can work c out using plane sections remain plane assumption.
2. "recorder Element -file Element1.out -time -ele 1 section 2 fiber 0.10 0.10 strain" which will give you the strain of the closest fibre to the position (0.1, 0.1) in the local YZ plane of the section 2. If you record the strain of 2 different points within the section you can determine c using the plane section assumption
