## Input

When you execute the Plate > Force & Stress Table function, the Records Activation Dialog is displayed. Here, you can select the target nodes, elements, load conditions, construction stages, and more, and then click the **OK** button. If you click **Cancel**, the table will be generated for all the targets, which may take a considerable amount of time depending on the case.

Refer to Results Table of "Usage of Table Tool" for the usage of Records Activation Dialog.

Refer to Usage of Table Tool and check the following data:

** 1. Plate Force (Local)**

**Elem** : Element number

**Load** : Unit load case/combination

**Stage** : Construction stage

**Step** : Sub-stage

**Node** : Node number

**Fx** : Element's internal force in the element's local x-direction

**Fz** : Element's internal force in the element's local z-direction

**Mx** : Bending moment about the element's local x-axis

**2. Plate Force (Global)**

**MX** : Bending moment about GCS X-axis

**MY** : Bending moment about GCS Y-axis

**MZ** : Bending moment about GCS Z-axis

When performing moving load analysis, only the member forces per unit length are required. Therefore, when using the Plate Force (Local, Global) Table to output nodal forces, the results will be displayed as '0' since they are not relevant in this case.

**3. Plate Force (Unit Length)**

**Elem** : Element number

**Load** : Unit load case/combination

**Stage** : Construction stage

**Step** : Sub-stage

**Node** : Node number

**Fyy** : Axial force per unit width in the element's local y-direction

**Fxy** : Shear force per unit width in the element's local x-y plane (In-plane shear)

**Fmax** : Maximum principal axial force per unit width

**Fmin** : Minimum principal axial force per unit width

**Angle** : Angle formed by the element's local x-axis and the axis of the maximum principal axial force

**Mxx** : Bending moment per unit width in the x-axis direction of the element coordinate system.

**Myy** : Bending moment per unit width in the y-axis direction of the element coordinate system.

**Mxy** : Torsional moment per unit width about the element's local x-y axes

**Mmax** : Maximum principal bending moment per unit width

**Mmin** : Minimum principal bending moment per unit width

**Sig-xy** : Shear stress in the element's local x-y plane (In-plane shear)

**Sig-Max** : Maximum principal stress

**Sig-Min** : Minimum principal stress

**Angle** : Angle formed by the element's local x-axis and the axis of the maximum principal stress vector. Angle is not generated for Envelop Type load combination since concurrent stresses cannot be calculated for the Envelop Type load combination.

**Sig-EFF** : Effective stress (von-Mises Stress)

For the method of calculating principal stresses, effective stresses and maximum shear stresses for each load combination type, refer to the explanations at the bottom of the Combinations page.

**ANG** : Angle formed by GCS X-axis and the axis of the maximum principal stress vector. Angle is not generated for Envelop Type load combination since concurrent stresses cannot be calculated for the Envelop Type load combination.

**Sig-EFF** : Effective stress (von-Mises Stress)

The Stage and Step columns in the Analysis Result Table are produced for a construction stage analysis or Hydration Heat Analysis. The Step column is produced also for a geometric nonlinear analysis.

The calculation method for principal stress, von Mises stress, and maximum shear stress based on the load combination type is described in the "Combinations" section.

**6. Wood Armer moment (Unit Length)**

**W-A Moment Top/Bot Dir1/2** : Wood Armer moment value for the respective preceding combination of moments.

** 1 Wood-Armer formula for skew reinforcement**

**1**Wood-Armer formula for skew reinforcement**Slab Design Forces**

midas Civil provide design forces in the reinforcement directions for skew reinforcement according to the Wood-Armer formula.

From the analysis results, following plate forces about the local axis are calculated.

**mxx****myy****mxy**

In order to calculate design forces in the reinforcement direction, angle α and φ will be taken as following figure:

x, y: local axis of plate element

1, 2: reinforcement direction

α: angle between local x-direction and reinforcement direction 1

φ: angle between reinforcement direction 1 and reinforcement direction 2

Firstly, internal forces (mxx, myy and mxy) are transformed into the a-b coordinate system.

Then, Wood-Armer moments are calculated as follows:

**2**

Values of Ma, Mb and Mab are repeated four times in the table, because for moving load analysis, midas Civil takes into account different combinations of concurrent forces in order to achieve maximum wood armer moment for top or bottom rebar parts in any specified direction. E.g. the combination of moments to be used for maximizing “top dir-1” and “bot dir-1” moments may be quite different since the concurrent forces required to maximize these moments can be different.
