CONNECTION STIFFNESS IMPLEMENTATION PROCEDUREFOR STAAD PRO USERS
Modeling of Global Frame Using SidePlate® Connection Technology:
Pg 1 of 5
USING NON-PRISMATIC BEAM SECTIONS is the most accurate way of implementing SidePlate® connection
properties in STAAD PRO.

The inherent SidePlate® connection stiffness can be implemented within STAAD PRO by replacing the beam
and column stiffness with the SidePlate® stiffness. The SidePlate® connection provides a 100% rigid panel
zone at the column and increases the beam section properties for a distance of approximately the beam
depth (Db) beyond the face of the column. Refer to the SidePlate® Tech Tips document for a description of
the different SidePlate® connection types and general design guidelines.
The stiffened SidePlate® section extends from column face to Dim A (shown in Figure 1). This stiffened
SidePlate® section, which consists of the physical side plates {A}, cover plates {B} and beam, has an
approximate moment of inertia (3) times that of the beam alone for SMF, IMF and OMF applications and (1)
times the moment of inertia of the beam for R=3 applications.

STEP 1: Create General Material Properties of RIGID LINK.
Under the General > Material tab, create an Isotropic Material "RIGID"
STEP 2: Create General Section of RIGID LINK in the User Provided Table.
Under the "Tools" drop down list, click on "Create User Table". Create a New Table with General
Section Type, assign the section name as RIGID and the parameters shown in the picture shown
below.

STEP 3: DETERMINE THE LENGTH OF RIGID LINK
• RIGID LINK length at beam end is determined by half of column depth
• RIGID LINK length at column end is determined by beam depth + 3"
RIGID LINK LENGTH = 7"FOR A W14X211 IN THIS EXAMPLE
RIGID LINK LENGTH = 36"FOR A W33X130 IN THIS EXAMPLE
W33x130
W33x130 NPSP
W14
x211
STEP 4: SPLIT BEAM AND COLUMN MEMBERS
• Select the lateral beam or column member, right click and choose "Insert Node".
• Input the RIGID LINK and Dimension A length in ft, select "Add New Point" and click on "OK".
• Under the General > Property tab, highlight the RIGID section, select all the
RIGID LINKS in the model, choose the Assignment Method "Assign To Selected
Beams", and click on "Assign". Repeat the same procedure for assigning
NON-PRISMATIC SIDEPLATE BEAMS.
STEP 5: ASSIGN RIGID LINK AND NON-PRISMATIC SIDEPLATE SECTION PROPERTY
• Keep all the RIGID LINKS and NON-PRISMATIC
SIDEPLATE BEAMS Fixed and no Release.
• To obtain the approximate connection plate weight for a specific project,
simply email your STAAD PRO model to [email protected]. One of
our engineers will review the model for validation and reply with the
connection plate weight.
STEP 6: CONNECTION WEIGHT
• See Appendix for examples.

Pg 4 of 5
Create and assign Non-Prismatic SidePlate Beam Properties: “Tools” on the top menu bar, click on “Create
User Table...”, when “Create User Provided Table” window pop-up, click on “New Table”, choose WIDE
FLANGE in the "Select Section Type" window, then click on "Add New Property".
In the “Wide Flange” window, input NPSP property values, and click “OK”.
Below is the W33X130NPSP example shown:

Assign NPSP beam properties to STAAD Pro model: Click on "User Table..." button in the "Properties"
window, add the NPSP property to the "Properties - Whole Structure" table.
Select the NPSP member(s), then click on "Assign" button to change the member properties.
