NORMAN I. NoIuIsH ROCK STRENGTH PROPERTIES AMD

At higher normal stresses, crushing of the rock fragments begins to take place, with the result that the friction angle diminishes. The shape of the strength envelope is related to the degree of fracturing and the strength of the intact rock (see Section 4.2). Weak intact rock: Rock such as the tuff shown in Figure 144 is composed of fine-grained

Rankin's Formula Example for Column

If column is short, calculated load will be known as crushing load. And load will be buckling or crippling load, in case of long column. This formula only gives the ultimate load, but columns are design on safe load. In order to get safe load, divide ultimate load ( Load obtained from Rankin's Formula) with factor of safety (F.O.S).
