Top Questions on Earth pressure theories
- Consider the statements P and Q related to the analysis/design of retaining walls.
P : When a rough retaining wall moves toward the backfill, the wall friction force/resistance mobilizes in upward direction along the wall.
Q : Most of the earth pressure theories calculate the earth pressure due to surcharge by neglecting the actual distribution of stresses due to surcharge.

- A simply supported, uniformly loaded, two-way slab panel is torsionally unrestrained. The effective span lengths along the short span (x) and long span (y) directions of the panel are lx and ly, respectively. The design moments for the reinforcements along the x and y directions are Mux and Muy, respectively. By using Rankine-Grashoff method, the ratio Mux/Muy is proportional to
