Nonlinear Calculation Total

The upper part of the window provides a summary of the governing serviceability limit state designs. The lower part displays the intermediate results of the current FE node or grid point (of the entry selected above) including all design-relevant parameters. You can expand the chapters with and close them with .

Figura 5.9 Window 3.1 Nonlinear Calculation Total

Figure 5.9 shows the result window of a nonlinear serviceability limit state design. The method of check is defined in the Serviceability tab of window 1.1 General Data (see Figure 3.8).

The columns are described in chapter 5.4.

The symbols signify the following designs:

Símbolo Design SLS

uz,local

Deformation in cracked state (→ chapter 2.8.2.4) according to specifications in window 1.3 Surfaces

wk

Limitation of crack width (→ chapter 2.6.4.12) according to specifications in window 1.3 Surfaces (see Figure 3.18)

σc

Limitation of concrete compressive stress (→ chapter 2.6.4.7) according to specifications in window 1.3 Surfaces (see Figure 3.19)

σs

Limitation of reinforcing steel stress (→ chapter 2.6.4.8) according to specifications in window 1.3 Surfaces (see Figure 3.18)

The deformations, crack widths, and stresses represent the results in cracked sections (state II).

The crack widths wk for the intermediate results refer to the reinforcement directions. For example, the value for wk,I,-z(top) represents the crack width for the first reinforcement direction at the top side of the surface; the crack runs perpendicular to reinforcement direction 1.
