Ductility design of RC columns. Part 1: consideration of axial compression ratio

HKIE Transactions, 2016
ABSTRACTTo evaluate and quantify the effect of the axial compression ratio (ACR) on the seismic performance of reinforced concrete (RC) columns, studies of analytical relationships between the axial compression and the mechanical behaviour of RC columns were conducted, followed by a comprehensive statistical analysis with 474 sets of experimental data.

Ratio of cube strength to axial compressive strength of rocks

Soviet Mining Science, 1978
1. For salt rocks of the Starobinsk potash salt deposit a hyperbolic relation exists between the compressive strengths and h/d, determined by the equation $$\sigma = 124.6 + \frac{{178.2}}{{h/d}},kgf/cm^2 .$$ 2. The ratio between the axial compressive strength (h/d≥2) and the cube strength (h/d=1) was as follows: for salt rock 0 ...
