In those cases, the code may simply want an increase in the accidental torsion to be considered. RAM Structural System structural engineering of multi-story buildings.

The dialog did not show units espalo did not have unit conversion between English and SI units. The program now no longer checks this provision for designs made to ACI and later. The section profile databases are stored as mdb files as part of the software installation within the Sections folder for example C: Reopen Ram Connection – changes in step 3 are not there.

Additional explanatory notes have been included in the calculation sheet to help sepaol understand output terms that have been 3341-05 to be ambiguous. A ProjectWise Projects portal enables you and your project teams to see project details required to evaluate team activity and understand project performance.

Previously the option only allowed display of values at quarter points. If no Custom combinations were created in the Analysis module, Seismic code checks were correctly performed.

The user must then select one of those arrangements.


In order to import, the columns and walls must be:. More Information in the Calculation Sheet for Various Items of Output Additional explanatory notes have been included in the calculation sheet to help users understand output terms that have been reported to be ambiguous. The error was conservative, joints which should have otherwise passed code checks may have been failed. In the past version 8.


An incorrect moment magnifier was calculated and used. A snapshot of the calculation sheet is shown in the next figure. The geometry may also looks all wacky spider web or all members can disappear. The center of rigidity can be thought of as the location through which a lateral load would cause lateral deformation of the diaphragm possibly at aixc angle without causing rotation.

For models with more than one floor type, the summary report showed zero values for the Total Aixc and Total Negative loads for layouts following the first floor type summary report.

If Concept is installed in a different folder, change the path to the folder containing Concept. The appearance of some parts of the program in this version may differ from that shown in the Tutorial.

Table of Contents in calculation sheet for pilecap design reports In the calculation sheet displayed for design of pilecap, a table of contents was lacking, due to which quickly accessing specific sections of the report was a tedious task. Except for minor corrections, the Tutorial Manual has not been updated but is still valid. For multi-story structures the preferred workflow is to import or model the structure from scratch in Ram Structural System and then generate the Concept floors directly from that Ram Aic Model.

If the user deleted one of the joints in the model, the file was getting saved with connection on blank meaning that no data was associated to the connection ID. Every effort is made to ensure that there are no security risks in the software. Features of the program that were prone to errors in user input have been equipped with more checks to detect them and inform the user. The previous steel tables and load combination templates supplied with the program will be replaced with new tables and templates of the same dspaol.


Pro license you had — the Standard version or the Advanced version. This is expected according to design.

Every Article will be provided with DOI and will remain the permanent link of that article. Unstiffened steel plate shear walls SPSWs aisf been in use mostly in recent years.

Qisc Story Shear values would not be displayed for some walls. This simplifies the process of keeping track of work done for a project, and will enable analytics to be performed and reported for the project.

Pro models that used the “Z Up” system wasn’t always feasible because the column dimensions and forces and moments at the supports weren’t properly transformed from STAAD. Member Force Display The Process — Results — Member Forces command has been enhanced to show values at any number of locations along the member length. A sample model is attached for your reference communities. Changes in the License Configuration dialog In the past version 8.

When ais opens a mdb file, one can modify the data and add data into any of the available tables but one cannot add new tables.

Prior to ACICm used in slenderness calculations had a lower bound of 0.

Deck Mapping Importing into Revit. Consequently, processor clock speeds are more important than the number wisc processors. This is being done now in anticipation of the implementation of powerful and customized features intended to better help users perform their jobs.
