Introduction
The Software Release Report for STAAD.Pro 2006 contains
detailed information on additions and changes that have been
implemented since the final build of STAAD.Pro 2005. This
document should be read in conjunction with all other STAAD.Pro
manuals.

AD.2006.1 Features affecting the Pre-Processor
Several new features have been added and existing features have
been modified in the pre-processor section of the program. They
are explained in the following pages.

AD.2006.1.1 Physical Member Interface
Purpose

STAAD will allow grouping analytical predefined members into
physical members using a special member group PMEMBER.
PMEMBER defines a group of analytical collinear members, with
same cross section and material property.

To model using PMEMBER, one needs to model regular analytical
members and the start grouping those together.

While creating a PMEMBER, the following are the pre-requisites,

1.

Existence of the analytical members in the member-list.
2.

Selected members should be interconnected.
3.

The selected individual members are collinear.
4.

Local axis of the individual members comprising the physical
member should be identical (i.e. x, y and z are respectively parallel
and in same sense).
5.

A member in one Physical Member Group should not occur in any
other Physical Member Group.

Description

PMEMBER can be created either in modeling mode or Steel-
Designer mode. Modeling mode and Steel-Designer mode
PMEMBER-s 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 will be
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)

Example:

JOINT COORDINATE
1 0 0 0 6 10.0 0 0
MEMBER INCIDENSE
1 1 2 5
DEFINE PMEMBER
1 TO 5 PMEMB 1

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.

At present, a Physical Member can be loaded with Uniformly
Distributed Load and Moment, Concentrated Load and Moment,
and Trapezoidal Load. The command syntax is as follows:

PMEMBER LOAD
{Pmember List} UNI / CON / UMOM / UCON / TRAP f1 f2 f3 f4

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.







Graphical User Interface for Physical Member:

The following steps are to be followed for creation of a Physical
Member:

Creation of a Physical Member:

1.

Make a frame model in STAAD.Pro, comprising of few
consecutive beams.

2.

A new toolbar Physical Member Toolbar is seen with icons
containing Toggle Physical Member Mode, Select Physical
Member Cursor and Form Member, as highlighted in the picture
below.

3.

Select few analytical members which are Collinear and
interconnected, as shown in the
picture. Refer the pre-
requisites of the analytical members in the previous section to
form a Physical Member.

4.

Now, either by clicking the Form Member button on the Physical
Member Toolbar, or by clicking Form Member from the context
menu, the Physical Member can be created.



Figure 1

5.

The details of the formed Physical Member can be seen in the
General Physical Member page at the right pane of the
window as shown in the figure.



Figure 2

Assigning Member Property to a Physical Member:

1.

To assign Member Property to the Physical Member, at first we
need to create some Physical Member properties, which are
different from Analytical Member Properties

To create a Physical Member Property, we should be in the
Physical Member Mode by clicking on the Toggle Physical
Member Mode button and go to the General Property page.

2.

Create a new Property, and this new member property will be
assigned as a Physical Member Property, as shown below, marked
as Physical. Only the Physical Member properties can be
assigned to a physical member, and no analytical member property
can be assigned to a physical member.


Figure 3
3.

Assign this member property to the selected Physical Member.

Note: For a Physical Member, whose physical member property
is already assigned, the individual analytical members in that
Physical member will adop
