Specification of soil subsidences with predefined shape (Input Table)

Data description/conditions:

X-P:

X-coordinate of data reference point with maximum subsidence

None / Required

(Column may be toggled to AX-L, AX-LP, NODE, ELEM or IDENT, see toggling data tables.)

SUBZMAX:

Maximum value of subsidence in z-direction

≠ 0. / Required

(For downward subsidence this value must be negative.)

UNCF:

Uncertainty factor for subsidence ¹

≥ 1.

[Default: 1.5]

LENGTH:

Length over which subsidence varies from zero to maximum value by half of sine wave cycle / length of block subsidence

> 0.

SINESHAPE:

Type of sine wave

Prescribed names: Double / Left / Right / Block

(Double: Half of sine wave length at both sides of X-P

Left: Half of sine wave length before X-P, zero after X-P

Right: Half of sine wave length after X-P, zero before X-P

In all cases the maximum value of twice the sine amplitude occurs at X-P.

Block: Block shaped subsidence with jump from zero to SUBZMAX at X-P, constant value between X-P and X-P + LENGTH, and a jump back to zero at X-P + LENGTH.)

¹ SUBZMAX is always multiplied by UNCF.
