Question

If the eccentricity of total self-weight W of a masonry dam at its base is equal to one-fourth of base width B, then the maximum pressure at the base is given by

• A. 2W/3B
• B. 4W/3B
• C. 5W/2B
• D. 8W/3B

Answer 1

The correct option is D 8W/3B

$\text{Masonry cannot take tension.}\text{So maximum pressure for}e>\frac{b}{6}\text{is}$

${\rho }_{max}=\frac{2W}{3[\frac{B}{2}-e]}Givene=\frac{B}{4}$

$\therefore {\rho }_{max}=\frac{8W}{3B}$
