Дорожная карта Robot - весна 2021

 Опубликована публичная дорожная карта для Robot  и можно сказать. что в ней есть несколько действительно стоящих и долгожданных вещей. Например, планируется открыть доступ к некоторым алгоритмам по расчету железобетонных конструкций. Это поможет привлечь энтузиастов для внедрения отсутствующих норм расчета. Также планируют существенно перебрать аналитическую модель в Revit, что позволит делать просто немыслимые вещи, как назначать аналитику для лестниц. 

Analysis 

Analysis solvers are essential enablers for the overall Analysis & Design process. Even though Robot has been renowned for its versatility and performance for meshing and analysis, we should expect it to continue to grow within this area: new analysis methods, faster and multi-processing methods supporting variety of platforms and being connected to open standards.  Below are specific projects we are working on or plan to invest in: 

Gravity Analysis with Load Takedown method – The three primary objectives for this new capability is to enable engineers to: 

  • Determine reactions on foundations in very early design stages when the upper part of a building is yet being worked on.
  • Understand building behavior to determine best columns layout distribution.
  • Get loads transferred to individual objects so that local code check is possible with engineers’ traditional and handy code checking tools or even spreadsheets.

Updates to design codes for Seismic analysis – We plan to update the following design codes for Seismic analysis:

  • Portugal: POR NP EN 1998-1:2010
  • France: FR NF EN 1998-1/NA

Improved results accuracy for forces reduction over walls – Improved reduction over walls would allow to reduce bending moment concentrations in more accurate way. With that, calculated reinforcement could be reduced as it would be calculated by taking into account bending moment values from supporting wall edges.

Improved results accuracy for seismic calculation with eccentricities for spectral methods – This is to align seismic analysis results concerning sums of reactions with reduced results for building stories. New calculation procedures would make it possible to obtain torsion values corresponding to seismic analysis results determined by equivalent lateral force method.

Stiffness modifiers for all directions of members and panels without specifying an orthotropic panel –
We plan to introduce reduction in compression Ax and shear Ay, Az for members. General stiffness reduction coefficients for panel would allow to simulate stiffness reduction caused by such effect as panel cracking without orthotropic panel definition.

Additional parameters for seismic analysis for US codes – We plan to add additional parameters such as: Seismic Group, Site Class, Short and 1-sec, Period Response Accelerations, Fundamental Period and Response Modification Factor, etc.

Additional mass as a substitute for the last story ★ (e.g. roof) for simplified seismic analysis – which will help engineers take into account masses for structural elements (which might have significant mass) that as such are typically not taken into account in seismic analysis.

Loads and masses application to centers of rigid diaphragms ★ – which will make it possible for engineers to apply custom lateral loads to building slabs. This feature would enable definition of additional loads and masses in rigid diagrams’ mass center. It will result in more accurate internal forces calculation, avoiding unnecessary loads and mass eccentricity definitions.

Code Design

In this category, we cover investments in design codes to help our users be compliant with latest regulation for many countries. Local codes enable end-to-end analysis to design workflows for engineers to take design decisions for whole buildings and at objects level. At the same time, Robot, along with Revit, is open to be a platform for specialized and tailored-where-needed code design tools from the broader partner ecosystem, especially in the areas where it intersects with model-based detailing workflows. Below are specific projects we are working on or plan to invest in:

To accommodate growing demands to customize and extend country specific design codes, we would like to make some of our design code algorithms available and open for public★. As this happens, local experts and communities could help us deliver country specific regulations that complete Analysis and Design workflows natively with Robot.  In response to what’s been discussed on the User Forum, we are inviting experts and communities from a few countries to co-develop reinforced concrete design codes for Robot. We hope it will help address some of the top voted requests from the Idea Station for Robot.

To get Robot prepared as a platform to support new codes, we would like to fill the gap with a few country-specific components: New material and rebar databases for Brazil 

Similarly, to enable Analysis processes for the new countries, we plan to ad Load combination regulation for Brazil ★
Below are additional new and updated codes we are planning to implement:

New codes or updates for Structural Steel:

  • Denmark: DK DS/EN 1993-1-5:2006/A1:2017

New codes or updates for Reinforced Concrete:

  • US: ACI 318-18
  • UK: NA+A2:14 to BS EN 1992-1-1:2004+A1:2014
  • Poland: PN-EN 1992-1-1:2004+AP3:2018
  • France: NF EN 1992-1-1/NA March 2016

New Codes or updates for Load combinations:

  • Denmark: EN 1990 DK NA:2013
  • Finland: SFS-EN 1990/NA:2016

Usability Enhancements

In this area we are trying to capture and respond to users’ feedback related to overall productivity and ease of use for Robot. This includes small fixes that address annoying product gaps and enhancements that increase engineering productivity and save time.

  • Rounding up coordinates★ –to enable users to control and clean up coordinates for whole structures or selected nodes, panels and members, which would help users ensure model connectivity and consistency, including the model data imported from Revit and other sources.
  • Creating elements through nodes numbers – to provide those who like identifying geometries through numbers, rather than graphical placement with coordinates one other method for quick and easy model creation. We plan to also include a quick switch across different modeling methods.
  • Ability to display displacement individually for XYZ directions – to help users better understand and measure displacement impact in the context of a given coordinate system’s axes.
  • Usability improvements for Results exploration and diagrams/maps display in the areas of
    – Diagrams Normalization
    – Colors management
    – Legend clarity for screen shots purposes
    – Axis direction on panels

Analytical Collaboration in BIM ★This is an important category of improvements as it sets forth and responds to users’ requirements around desired analytical modeling productivity and collaboration practices. Not only does it need to foster engineering productivity and freedom of capturing design decisions in a modeling environment, it should also help engineers work with the broader design team in a modern and effective manner.

Having Robot being shipped and developed along with Revit – the BIM authoring platform in the Autodesk AEC Collection – provides the opportunity for further modernization of the overall user experience as regards to structural BIM workflows.

We are reimagining Analytical Modeling within Revit so that:

  • Engineers could create Analytical Model in BIM with freedom and versatility that they experience with Robot and other analysis tools
  • Revit and Robot (and the broader analysis ecosystem of Revit) could bidirectionally exchange and synchronize analytical data without any leaks of information or mapping challenges
  • Coordination between Analytical and Structural Physical model, and in general, Structural and Architectural models could benefit from Revit, Docs and BIM Collaborate Pro coordination

We plan to add new types of capabilities in Revit to make it possible for users to:

  • Model with analytical lines and surfaces in context of physical model in a way so that engineers could decide what the physical-analytical relation should be as they go: element by element, but in the same time having a whole-building perspective on how an analytical representation should look like as an abstraction of a whole building.
  • Start modeling with an analytical geometry first and to simply follow up with its physical counterpart, especially applicable for engineering driven types of projects and structures
  • Associate analytical lines or panels to any physical objects, including generic objects, stairs, etc.
  • Reimagine collaboration across Robot (also other analysis products) and Revit for:
    – Fully bidirectional and seamless synchronization of analytical lines and panels
    – Cross sectional properties exchange, etc.

Last but not least, we will continue enhancing Analytical Automation with Dynamo scripts that is open for customization, that drives Analytical model creation for a given type of structural models, whether it would be a framing structure, a building or a bridge.

So what does it mean to Robot users? Depending on your design project type, whether you’re working as part of a BIM team or in a typical CAD manner, we’re reimaging Analytical Modeling so that you would be able to interchangeably use or Robot or Revit to create your Analytical Model to run analysis and design from, keep the analytical data as part of the Common Data Environment, use design output to annotate engineering documentation and hand-over results and design intent as input data for further phases of the process, especially detailing (e.g. rebar or steel connections) in Revit.
