Static Load Cases

Define static load cases, or modify or delete previously defined load cases.

Static analysis is carried out for each static load case entered by this function. The analysis results can be interactively combined in "Combinations". Apply this feature to assign the load cases necessary to form the geometric stiffness matrix in the P-Delta or buckling analysis.

From the Main Menu Select Load > Static Load Cases.

Select Static Loads > Load Cases in the Menu tab of the Tree Menu.

Shortcut key : [F9]

Click to the right of the Load Case Name field in the dialog boxes of various functions purposed to specify static loads to define or modify static unit load conditions.

Static Load Cases dialog box

 

When defining or adding new static load cases

Enter the following items and click .

Name: Static load case name

Type: Select the load type from the list of static unit load cases (refer to Note)

The Combinations command uses the list to automatically create the load combinations according to the provisions in the design codes of each country. The list contains a total of 25 types of loads. 'User Defined Load' in the list may be assigned when unusual load types are encountered. However, this load case is not considered in the auto-generation of load combinations.

Description: Enter a short description of the load case

 

To modify previously defined load cases

Select the relevant load case from the load cases list at the bottom of the dialog box, then modify the entries and click .

 

When deleting previously defined load cases

Select the relevant load case from the load cases list at the bottom of the dialog box and click .

 

Note
The unit load case types are as follows: Note that the names of the unit load cases listed below can differ from the notation given in the codes.

User Defined Load (U)

Dead Load (D)

Live Load (L)

Roof Live Load (R)

Wind Load on Structure (W)

Earthquake (E)

Temperature (T)

Snow Load (S)

Rain Load (R)

Live Load Impact (IL)

Earth Pressure (EP)

Buoyancy (B): Buoyant force

Ground Water Pressure (WP): Hydraulic or water pressure

Fluid Pressure (FP)

Ice Pressure (IP)

Wind Load on Live Load (WL): Wind load acting simultaneously with the traffic live load

Longitudinal Force from Live Load (BK): Longitudinal force component due to horizontal live load

Centrifugal Force (CF)

Rib Shortening (RS): Rib Shortening

Shrinkage (SH): Effect of concrete shrinkage

Creep (CR): Effect of concrete creep

Prestress (PS): Pre-stressing force

Erection Load (ER): Load during construction

Collision Load (CO): Collision or impact load

Construction Stage Load (CS)

Note
The Load Type of a load case to be used in a construction stage analysis must be defined as "Construction Stage Load". Otherwise, the results of a general analysis for the corresponding load case, irrelevant to the construction stage analysis, will be produced in the “Final Stage” in the post-processing mode Stage Toolbar.

Braking Load (BL): Vehicle braking load

Settlement (STL)

Wave Pressure (WPR)

Crowd Load (CL)

Temperature Gradient (TG)
