PMEMBER can be created either in modeling mode or Steel-Designer mode. Modeling mode and Steel-Designer mode physical members will be labeled as M and D, respectively. Modeling mode PMEMBER will allow variable cross-sections. Steel-Designer mode will allow importing PMEMBER-s created in modeling mode.
Following STAAD commands related to PMEMBER are implemented.
DEFINE PMEMBER PMEMBER PROPERTY PMEMBER CONSTANT PMEMBER LOAD PRINT PMEMBER FORCE
To define a Physical Member, the following command is used after the MEMBER INCIDENCE Command:
DEFINE PMEMBER member list PMEMBER pmember-no
To define the member property of a Physical Member, the following command is used:
PMEMBER PROPERTY pmember-list PRIS …
The Physical Member supports all types of member properties available in STAAD.
If multiple definitions of member properties for a particular analytical member is encountered (e.g. analytical member properties is defined twice, once via PMEMBER PROP command and again via MEMBER PROP command, then MEMBER PROP command will override PMEMBER PROP definition.
To define the Material constants of a Physical Member, the following command is used:
PMEMBER CONSTANT E CONCRETE pmember-list DEN CONCRETE pmember-list …
Any member, which is a part of any PMEMNER is not allowed to be assigned constants explicitly.
After the analysis, the Post Analysis results of a PMEMBER can be seen by using the following command:
PRINT PMEMBER FORCE
This command will produce member forces for all the analytical members in the group.
