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

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.
