Lateral pressure coefficient on lateral wall.
As seen in this figure, there is a general trend towards decreasing
lateral pressures on nonyielding retaining walls with decreasing EPS density at equal thickness of geofoam panels.
The main objective is to identify the
lateral pressure coefficients.
Next, three schemes when the
lateral pressure coefficient is equal to 1.5 have been numerically simulated.
Hence, it is obvious according to equation (2-4) that in presence of
lateral pressure, axial compressive strength of the element is increased.
where [R.sub.bu] is concrete's resistibility under unixial compression; k is a
lateral pressure coefficient, which depends on edging draft level m = [[sigma].sub.bxu]/[[sigma].sub.bzu] and calculated by formula
--For medium rotation, say [(d/2).sub.max] = 1 mm (medium rotation), with moving back the wall, no significant increase in induced
lateral pressure is observed.
Firstly only the affection of the
lateral pressure [[sigma].sub.c] on the GFRP pipe is considered.
This figure shows that increasing water depth will decrease
lateral pressure in both active and passive conditions.
Although a tilted patella is usually associated with increased
lateral pressures, diminished medial patellofemoral contact, and a tight retinaculum, none of these may occur in the presence of certain patellofemoral morphologies.
Located along the shaft of the drill, the actuators apply
lateral pressure against the side of the borehole to alter the orientation of the drill head.
Both excellent fuel efficiency and quietness are achieved through the efficient transmission of driving force by optimizing the
lateral pressure applied to the belt, along with the durability of the belt.
