Potential environmental issues associated with leakage from an acidic tailings pond include depressed pH, elevated metals, although also possibly suspended solids in surface water.
Some possible ways to address this question include:
1. a site-specific evaluation of the potential environmental...
Ron- you're right; lambda is a function of kL/r, which is about 90 in this case, and I have a level of "comfort" about the member selection, since the stress (P/A) is relatively low. However, I prefer to quantify the strength at onset of buckling, and there does not appear to be...
According to CSA S16.1-M94; Axial compressive resistance is:
Cr=phi x A x Fy x (1 + lambda^2n)^(-1/n); (section 13.3.1)
- appendix D suggests how to determine lambda
- however, n is specified only for W,I, Box,HSS, and WWF members and no guidance is given regarding L-members.
- Specifically...
