To begin the tutorial, double click on the RAM Structural System icon on the desktop. The screen that appears is the RAM Manager program. In the middle of the screen there should be a Bentley logo which indicates that you are running Release 14.00 (or later).

Before you even create your first model you can adjust the program defaults. The defaults cover everything from User Name, to Steel preferences and beyond. If you had another version of RAM Structural System prior to installing Release 14.00, those previous default settings should still be set. With each new version there are new defaults for new features which should be checked however.

• Select Tools - RAM Defaults Utility. A message pops up indicating that the defaults only affect new models. For existing models, the various criteria menu options throughout the program modules can be used to modify the model. Click [OK] to close the warning.
  Feel free to adjust any of the remaining defaults.

Once that is complete it's time to create your tutorial model.

• Select File - New.
  If this is the first time using the program then the following dialog box will pop-up asking you to select a working directory. This is where temporary files will be saved while you are working on a RAM Model. The directory should be a local directory on the hard drive with complete read and write privileges. It needs to be set only once.
  
• If the default working directory is not what you would like, click the open folder icon on the right and then browse to a directory you do want to use and Click [OK].
  
• When the "New" dialog box opens, type MyTutorial in the File name field (notice the default file type is *.rss).
• In the Job Name field type Fundamentals.
• Select the desired Units (English, SI or Metric).
  NOTE: The units you select now set all the defaults for the model you are creating. There are a complete set of English (Imperial) defaults and another set of Metric/SI defaults which can be set in the Defaults Utility. There are subtle differences between SI and Metric units, but the default values are all the same. When using "English" units you can switch between feet and inches while modeling.
• Click [Save].

Model Status Lights

The model status lights keep track of the global status of the current model. The manager has 5 different light colors:

• Green - The module has been completed by way of analysis or design. All information is current and designs are valid.
• Yellow - Something has changed in a module that has affected the validity of results. Use designs with caution.
• Red - No analysis or design has been completed. A criteria has changed that invalidates designs or analysis. Results are no longer available.
• Light Blue - Columns selected by the user that pass all code checks.
• Gray - The module has no relevance to the model. For example, if you create an all steel model, the concrete modules will be gray.

The manager also has a legend in the bottom left hand corner that gives live status info for each module.

Selecting Criteria

There are several different criteria that can be set from the RAM Manager. These typically have an impact on all of the various design modules. Other, more specific design criteria are set within the individual design modules.

Live Load Reduction

To pick the appropriate code for Live Load Reduction:

• Select Criteria ­ - Member Loads
  
• Under Code for Live Load Reduction select IBC LL Reduction Method - General (BS 6399)
• Under Snow vs. Roof Live Load select Consider Snow Loads, Ignore Roof Live Loads.
  NOTE: While the program will allow you to model both kinds of loads it can only consider one type or the other in the design at one time.

Notice that there are several Building Codes available for Live Load Reduction, including SBC, BOCA, UBC, NBC of Canada, BS 6399, Eurocode, AS/NZ 1170.1, China GB 50009-2001 and Hong Kong. Selecting certain codes will make additional criteria specific to these building codes available in the Criteria Menu.

Also, there are three check boxes under Determining Number of Stories. If you have not changed the installation defaults, the bottom two check boxes will be checked. This setting is used by the program to determine how many levels are supported by a column. Some codes establish a maximum Live Load Reduction depending on the number of floors supported by the column and differentiate between floor levels and roof levels. For more information on the use of this setting, refer to the RAM Manager on-line documentation.

• Click [OK] to exit this dialog.

Self ­- Weight Options

To control whether or not the program automatically includes member self weight as part of the Dead Load case:

• Select Criteria ­ - Self-Weight.
  
• Check all of the items to match the above dialog and click [OK].
  NOTE: The program will now apply a vertical load to all members based on self-weight. The self weight forces generated by the program are automatically included as part of the Dead Load case (downward loads). Also, note that the masses used in the seismic force determination and dynamic behavior can be automatically determined according to the selections above, or can be assigned separately in the modeler and an estimated mass for beams, columns and slabs must be input as part of the loads. If the self weight of walls is checked above, then the mass of gravity and lateral walls will be included in the building mass based on the full story height. Calculated wall dead loads and masses are adjusted for openings in the walls.

Selecting Tables

The program references tables in the analysis and design of all models. The Master Steel Table includes all section designations and section properties for all available steel shapes. The installed master tables reflect the current state of available sections. When changes to the section properties or availability are made by AISC or other governing organization we make every attempt to update the files accordingly. You may modify the master tables yourself with any text editor (e.g. Microsoft Word Pad), but we recommend that you make a copy of the file for alterations first, as the default files will be overwritten when the program is reinstalled. Master table files have the extension ".TAB" and can be found in the Tables subfolder wherever the RAM Structural System was installed. For more information on table format, please refer to the RAM Manager on-line manual.

• Select Criteria - ­ Master Steel Table.
  

• Select RAMAISC (RAMUK) as the master table and Click [OK].

Besides the master table of sections, the program also utilizes Design Steel Tables in the optimization of the steel members. There are Design Steel Tables for Deck, Column, Beam, Smartbeam and Joist; their extensions are ".DCK", ".COL", ".BMS", ".CAS", ".JST" (and ".KCS") respectively. The Design Steel Tables include a listing of the sections in a particular order, which affects the program optimization. You can customize these tables to meet your specific needs or create new tables. Again, the RAM Manager on-line documentation has a complete description of the format of the design tables.

• Select Criteria ­ - Design Steel Tables.
  
• Under the Decks tab choose RAMDECKS (RAMUK).
• Under the Column tab choose RAMAISC (RAMUK).
• Under the Beam tab choose RAMAISC (RAMUK) for both default and alternate tables.
• Under the Smartbeam tab select RAMSMI for all four tables.
• Under the Joist tab select RAMSJI for the two standard tables and RAMKCS for the two constant shear tables and Click [OK].
  

For concrete members, the gross dimensions are always created directly in the model, but there is a Concrete Table which contains a list of reinforcement bar designations (names) along with cross sectional areas and diameters. All the reinforcement in the table will be available for use in the design of both concrete beams and columns. The Pan Joist Table contains a list of common pan sizes for use in pan joist construction. The reinforcement tables have extension ".REN" and the pan joist tables have extension ".PNJ".

• Select Criteria - Concrete Tables.
• Under Reinforcement Table select RAMASTM (RAMUKTYPE1M)
• Under Pan Form Table select RAMCECO and Click [OK].
  
  

Selecting Units

The units for any model may be altered at any time. Changing the units does not affect the physical model size of an existing model, it only alters the reports and on-screen displays. It is important to note that when you create a new file and pick the units you are also selecting which set of defaults to use. Changing the units after the model is created does not affect which set of defaults the program uses.

• Select Criteria - Units.
• Select English (or SI).
• Click [OK].

Additional Commands

There are several additional commands and settings which do not need to be invoked for the tutorial model at this time. These may be found under the Post-Processing and Tools menus in the menu bar. They include more criteria settings, report styles defaults, export options, etc. Feel free to examine or adjust the other items now.
