Application Interface

Modeling features in RISAConnection may be accessed through the ribbon toolbar, shortcut keystrokes, and the Connection Properties spreadsheet. You may use any or all of these options to interact with the software. The ribbon toolbar contains the tools required to create new models, save, print, access Global Project Settings, and the viewing options. The shortcut keys provide a fast way to access features should you use the program often enough to make them familiar to you. Finally, the Connection Properties spreadsheet contains all the user-input data to model your connection. These features are discussed in the sections below.

Menus and Toolbars

Title Bar

The bar at the top is called the title bar. The title of your project can be seen in the center of the bar, and the buttons are described below:

Button Function

Opens a previously created project
Adds a connection to the current project
Saves the current project

Ribbon Toolbar

Just beneath the title bar is the ribbon toolbar. This toolbar is divided into tabs to combine similar features and tools. Each tab is described below.

File Menu

The File menu contains the same model options as the Title bar (New, Open, Save, Print) with a few more. The additional functions are described below.

Home Menu

The Home menu contains some global buttons which effect the whole project and some buttons which are only applicable to whichever view you are in. For example, when you are in the 3D View, the Home menu will contain options for the view angle of the connection, and when you are in the 2D View, the options for toggling the loads, dimensions, and bolts become available.

The buttons are described below:

Shortcut Keys

The following keys (or key combinations) can be accessed as shortcuts to help speed up your modeling.

Shortcut Key Action
CRTL + O Open a File
CRTL + S Save a File
F1 Access Help Menu
F2 Switch to a 2D View
F3 Switch to a 3D View

Connection View

The Connection View provides options for viewing both the graphical display of the connection (in 2D or 3D view) and also viewing the result output report.

Graphical Display

Results Report

3D View

This view allows you to move your connection around and view it from all sides and angles. If you click on a specific connection element in this view it will highlight in the Connection Properties section. See the Graphic Display topic for more information.

2D View

Viewing the model in 2D allows you to see each of the components of the connection, complete with dimensions, bolt holes and some assembly views.

If you click on a specific connection element or dimension, that element or dimension will highlight in the Connection Properties section. See the Graphic Display topic for more information.

 

Certain views in the 2D view can visually show the loads applied to the connection, enhancing clarity and customization during design reviews and presentations.

This feature can be turned on by clicking the Loads button in the Home menu as shown below.

 

Reports

The Reports section shows all the results from the program, including component properties and design checks. See the Graphic Display topic and the design checks topics for more information.

Project Explorer

The Project Explorer shows the current project along with a list of all the connections in the project file.

Connection Properties

The Connection Properties gives ability to define all of the parameters for the connection. Modifying this data automatically updates the design check calculations in standalone mode. If integrated with RISAFloor and/or RISA-3D, then you must re-solve the connection after changes.

Note:

Connection

The Connection Title allows you to give your connection a specific name. The Connection Type gives a quick description of the components of the connection.

Seismic Detailing

The Seismic Detailing section allows you to assign seismic parameters to your connection. This is only applicable to the following connection types:

For more information, see the Seismic Detailing topic.

Connection Category

The Connection Category allows you to define the connection type (bolted vs welded) and orientation.

Beam Connection allows you to choose a Welded or Bolted connection.

Column Connection Type will only be available when the column is a rectangular HSS tube where you have the option to connect the beam to the Wide or Narrow face of the column.

Loading

This is the location where you define the loading on your connection. For shear connections, you will define the Shear Load and the Axial Load (if applicable), which are simply the shear and axial demand for the connection. Positive axial loads designate compression loads, and negative axial loads designate tension loads.

Note: 

Eccentric Moment Calculation

The Eccentric Moment Calculation input allows the user to control the eccentricities used to calculate the moment due to eccentricity at the connection.

Note: 

Moment Loads

For moment connections you will also define the Moment Load which is the required demand for the connection.

Additional Loading Inputs

In addition to these, there are some extra inputs described below.

Components

The Components section is a location where you can input specific details about the different connection components. This is where you define member sections, materials, bolt information, weld information and other specifics. Most of these items are self-explanatory. Here are some details of the inputs.

Member Sections

In the Shape Selection dialog you can choose which shape Database you wish to use. This allows access to all of the RISA foreign shapes databases. Note that RISAConnection will NOT read in shapes from the AISC_BACKUP database.

Channel Shapes

Channel members are available to be used as beam and brace members in the shear connections. Channel shapes are not currently available for moment connection members. When a channel shape is selected, the connector will always be attached to the back (web) of the channel section.

Note:

Tapered Wide Flange Shapes

RISAConnection will allow you to select a tapered WF shape for some members in some connections. Please see below for a list of available members.

Limitations:

k_des = t_flange

k_det = t_flange

k_1 = 0.5*t_web

k = t_flange

Double Clip Angles

When clip angle connections are not symmetric, the leg orientation will be specified as: 

Angle Orientation Explanation
LLS Long Leg Supported (or Short Legs Back to Back)
SLS Short Leg Supported (or Long Legs Back to Back) 
Hole Types

The following table shows the different types of available hole types:

Hole Type Explanation
STD Standard holes
OVS Oversize holes
XOVS Extra Oversize Holes (applicable to Base Plates only (per AISC 360-10 Table C-J9.1)
SSLH Short-slotted holes with the long dimension horizontal.

SSLV

Short-slotted holes with the long dimension vertical.
LSLH Long-slotted holes with the long dimension horizontal.
LSLV Long-slotted holes with the long dimension vertical.
 
Slip Critical
Assembly

The Assembly section is where you define other required dimensions such as: coping dimensions, edge distances, clearances, etc. Many of these values can be changed manually. Some of these values have maximum values that if you exceed that value we will use the maximum value. Other values are grayed out, meaning their value is dependent on other dimensional properties of the connection.

Notice that for all of the input, a more detailed explanation will be displayed in the display at the lower right corner of the screen.

Try clicking around in the various input cells to see this display change.

Here are some specific assembly details.
