~CFLSSLV

 

~CFLSSLV, LS1, LS2, INC, cmpaliv, cmpdead, KEYGDL

Reads and solves multiple load steps taking into account the construction process

SOLUTION: BRIDGES MODULE: Construction process

 

LS1, LS2, INC                                                                        

Range of load step files to be read and solved, from LS1 to LS2 in steps of INC.

cmpaliv

Prefix of the component with the elements to be activated. By default cmpaliv = CF_ALIV_ELEM_

cmpdead

Prefix of the component with the elements to be killed. By default cmpdead = CF_KILL_ELEM_

KEYGDL

0	The degrees of freedom of the nodes associated to the dead elements are fixed (value by default)
1	The degrees of freedom of the nodes associated to the dead elements are free.

Notes

- If a construction process has been defined using the bridges module (~CPDEF and ~CPSTPDEF commands), the components are automatically created and have the default names (CF_ALIV_ELEM_%Step% and CF_KIL_ELEM_%Step%, where %Step% is the number of construction phase). In addition, the tendons indicated in the construction process are activated and deactivated.

- If no construction process has been defined, the element components for the kill and alive process should be created. The name for the components must be as follows:
          cmpaliv prefix + %Step%
          cmpdead prefix + %Step%
where %Step% is the number of construction phase.

- The user should create and write, by using the ~CFLSWRT command, the load steps with the rest of the model actions (the prestress actions are added to these actions).

- The deactivation of tendons and elements is done before and after the activation.

- This command activates the FULL option of Newton-Raphson method (NROPT, FULL).

- ~CFLSSLV does not support restarts.
