Joint View/Update

The Process-Joint View/Update command is a powerful feature that allows the user to view detailed results of the design and detailing checks performed on a restrained (moment, rigid) joint, for the currently selected seismic code. If desired the column size and yield strength can be modified and the Code Check repeated. The modified data can then be saved to the database without requiring returning to the RAM Modeler.

Selecting Joint View/Update causes the target cursor to appear. Click the target cursor on a steel joint. This will cause the Joint View/Update dialog box to appear. The steel seismic provision joint Code Check is then performed based on the frame type of the column at the joint. For example, if the column is assigned a Special Moment Frame Type, and the beams Ordinary Moment Frame Type, then the joint is checked as a Special Moment Frame Joint (Same as column). The check is performed for all the selected standard provision mode load combinations, as well as all the selected seismic mode load combinations where specified in the seismic code.

The result of each check performed (including the code section), are displayed in the result list. The result of each check is indicated in the results list in the form of an icon in the row of the performed check. Double-click on a particular check to get a brief description of the icon displayed for that check. The icons are discussed briefly at the end of this section (refer to View/Update Result Icons). The header of this dialog box provides information about the frame member selected: floor type, member number, story level, and span coordinates.

The currently assigned column size appears in the drop down Column Size control, along with the column yield strength. The results of all the Seismic Code Checks for that joint are represented by the stoplight color. If green the joint successfully met all the requirements of the seismic code. If yellow then there are one or more seismic code checks that could not be performed and the engineer is responsible for completing. The results will clearly state which checks were not performed. If the stoplight is red then one or more of the seismic checks failed on that joint.

Changes can be made to the member size by selecting any size in the dropdown list, or to the yield strength by editing the value, and the member Code Check re-run by clicking the Analyze button. The results in the results list and the stoplight will be updated based on the results of the new Code Check. Once a satisfactory joint column member has been found, click the Update Database button to save it. Notice that when a new size is saved to the database the status indicator light turns yellow and a reanalysis is suggested to obtain accurate member forces.

The View Results button causes the Seismic Provision Joint Code Check output to appear on the screen. It is a detailed report of the Seismic Code Check results. The report includes design parameters and criteria, the controlling load combinations, calculated stresses and capacities, and the result of all checks performed.
