Advanced structural analysis software
Robot™ Structural Analysis Professional software provides engineers with advanced BIM-integrated analysis and design tools to understand the behavior of any structure type and verify cod compliance.
What's New in Autodesk Robot Structural Analysis Professional 2017 :
1. Improvement in Section Definition :
Now you can accept or prevent rotation of the coordinate system by 90 degrees (to have Iy >Iz). As a result, you can save sections in one not rotated coordinate system.
The local coordinate system of a cross section is specified as follows: the origin coincides with the center of gravity, while axes are rotated so that the moments of inertia with respect to these axes assume extreme values. Iy is usually considered maximal and Iz minimal. Sometimes, for example for symmetric sections, it may cause rotation of the local coordinate systems by 90 degrees. Such rotation of axes, where the Y axis is vertical and the Z axis is horizontal, is not always helpful. This improvement lets you keep the same position of the local axes, disregarding the relation between Iy and Iz. This way, you can keep the constant orientation of the local axes for the whole family of sections of different proportions.
2. Simulation and Analyses:
Norwegian Seismic Analysis According to Eurocode - New National Annex
The new Norwegian National Annex for EC8, that is NS-EN 1998-1:2004+NA:2014, has been implemented.
The Norwegian National Annex to Eurocode 8 (EN 1998-1:2004) has implemented changes in parameters of the recommended elastic response spectrum for ground type E. NS-EN 1998-1:2004+NA:2014 is now the default code for the Norwegian settings.
For projects created using the previous versions of Robot, select the NS-EN 1998-1:2004+NA:2014 code to include these changes. Otherwise, the previous edition of the code is used for these projects.
Improvements in Wind Loads on 2D Models According to Eurocode
The improvements apply to the following codes:
EN 1991-1-4 Wind Load
In generation of wind loads, the presence of dominant wall, as specified in point 7.2.9.(5), is now considered.
According to point 7.2.9.(5), for a building containing faces with openings whose area is at least twice the area of openings in the remaining faces of this building, the internal wind pressure should be taken as a fraction of the external pressure acting on this face.
This improvement applies to options for defining doors on the Permeability tab of the Snow/Wind Loads 2D/3D dialog.
3. Simulation and Analyses:
Density of Transversal Bar Reinforcement
This new feature allows you to display diagrams of density of required transversal reinforcement of bars and export it to Revit.
Access the transverse density feature from the RC Members - required reinf. layout by selecting Results

4. Robot-Advance Steel Link:
Robot-AdvanceSteel Link enables data exchange between Autodesk® Advance Steel® andRobot, through a complete set of functionalities like import, export, or synchronize.
After installing Robot, you can download and install the application from the Autodesk App Store website.
With Robot-AdvanceSteel Link, you can export a Robot structural model using the smlxformat. You can then import the smlx file in Advance Steel in order to detail steel connections and automatically generate fabrication documents. From Robot, you can also export values of internal forces with the model to the smlx file. After importing the file toAdvance Steel, you can use these values to perform code checking of connections.
Conversely, you can export a model from Advance Steel in order to perform structural analysis and code checking in Robot.
You can also track changes in the same model in both applications using the synchronization feature. Additionally, in Robot, you can track differences using a background that displays geometry of the Advance Steel model.
