News and Events

New Release – STAAD.Pro CONNECT Edition V22 Update 8 (22.08.00)

As part of our commitment to you to deliver new builds more frequently, we are making available this version which adds great new functionality to improve efficiency for engineers around the world and has resolved numerous issues that have been reported and thus highly recommend that you look to adopt this version and improve your working experience.

The principal developments and enhancements that are delivered in this new version of STAAD.Pro are:

Analytical Workflow Developments

Indian Wind loading

The wind loading routine in STAAD.Pro provides a method for distributing a pressure load on the envelope of a model based on prescribed pressures at given heights. This pattern is defined in the publication IS 875-part 3 which has been added so that the pressure pattern can be applied following rules based on constraints such as region, topology and structure type.

Two methods have been implemented. Firstly, a traditional method for creating the wind definition  given the location and structure criteria.

When creating a definition, note that the code needs to specified, then the pattern of wind intensity and height data can be generated according to the code.

Clicking the Generate button allows the conditions to be provided.

And the profile to be provided.

As a traditional wind load definition this can be added to load case with the relevant factor for the face under consideration

What is particularly exciting is the second method that has been added for the IS 875-pt 3 implementation for simultaneously defining and generating the wind loading.

This essentially supercharges the wind load definition and creates the loading on all four faces for wind coming from all four compass points in a single specification.

Accounting for both internal and external pressure coefficients significantly speeding up the time to manage wind loading.


Physical Model Updates

Extended Tank Wizard

The sample structure wizard template for creating multi-compartment to work in conjunction with the tank design in the Advanced Concrete Design (RCDC) module has been further developed to support tanks that are partially or fully buried and have a step in the wall thickness.

When the tank is buried, soil pressure loads which can include for a high-water table can be generated, including buoyancy effects on the base of the slab as well as additional surcharge loading.

Group management

Collating objects into useful collections has been seen to be a popular way for managing larger structures. This has been successfully utilised in the analytical workflow and based on feedback from a number of users, we have extended the capability provided in the Physical Workflow including providing the group data into the STD file. Additionally, the Physical Modeller now supports multiple group selection making model manipulation much easier.

Updated iTwin Service

In Update 7 the initial iModel cloud integration was introduced as a method to allow users to experiment with using STAAD.Pro physical models as an analytical part of an iModel repository that is associated with a ProjectWise 365 project.

The team driving this forward is now moving to an EAP which will provide an opportunity for users to provide a significant contribution to the development process including sharing the results of an AISC 360-16 design in an iModel.

In the meantime, to reduce confusion and ensure that the desktop interop service is provided, the cloud functionality in STAAD.Pro has been temporarily suspended and just desktop actions for working with local ISM repositories will continue with the simple Push and Pull operations.

Share Compatibility

The exciting ProjectWise 365 offering offered by Bentley to provides a number of valuable services including design review, issue resolution and document control built as a cloud solution including data storage which can be automatically synced with a local drive makes collaboration with team members easier and more professional. STAAD.Pro has worked closely with the PW 365 team to ensure system compatibility.

Improved Design

The support provided for design codes in various countries and regions around the world continues in Update 8. The three most significant developments provided in this release are:-

Steel Design CSA S16-19

The 2019 edition of the Canadian steel design code has been added to become the default Canadian steel design code It complements the earlier 2001, 2009 and 2014 editions. Note that if the year is not explicitly referred to, a design that calls for Canadian steel design will use this edition of the code.

Eurocode Steel Design for Envelopes

One of the challenges in designing steel members to the steel design module EN 1993-1-1 has been how to handle design is where both strength and serviceability need to be handled. These are defined in separate load cases or combinations. However, STAAD.Pro provides a method for defining an envelope, or collection of load cases which have been assigned a categorisation such as Strength or Serviceability: –

Now when the load list is defined by envelopes which have been assigned these categorisations are used to determine the appropriate checks to perform.

Updated Chinese Steel Design

The Chinese steel design workflow interface and methods introduced in Update 7 has been further refined with a large number of modifications that provide a more comprehensive design offering to the GB50017-2017 which include improvements:-

  • Improved handling of multiple parameters
  • Improved handling of materials
  • Improved colour coding of results
  • Improved handling of brace angles
  • Handling load combinations classified as ultimate or service
  • Extending the beam design to support axial as well as bending forces.

Chinese Wind loading

The introduction of wind loading to the Chinese code in Update 7 has also been given a number of improvements to assist in its use, following user feedback, including

  • supports the changes made for the Indian code
  • read the height of the structure from the model
  • wind loading for truss and circular structures
  • Additional methods for defining the range for face definitions.
  • Customising the pressure profile created by the Chinese code is now supported
  • Improved face identifications

Enhanced Plate Results

Determining key results from models with finite elements that have tens or hundreds of load cases has been made easier by providing these as envelopes both in tabular and contour format. .The maximum positive or negative value of a selected value identifies its magnitude and the load case which generated that effect allowing f=or a quicker identification of the driving forces and hence the actions to take to optimise the model.

Updated Steel Connection Design Workflow

The Steel Connection Design workflow has been updated to utilise the RAM Connection V13.5 dlls. This has extended the connection design with new gusset connections for IS800-2007

Additionally column-beam-brace joints and tubular mitred knee joints for the Australian and New Zealand codes have been added.

OpenSTAAD Updates

Being able to automate a number of processes with OpenSTAAD by engineers to improve their design processes is a benefit that has been rapidly growing. With Update 8 this benefit has been further improved with capabilities in four key areas:-

  1. Obtain the status of a running analysis process so now the analysis can be initiated, silently without the display of the analysis dialog if required, and when completed the necessary post analysis processes can be initiated.
  2. Support of the Direct Analysis commands and cable loading.
  3. Additional functions to manage CONNECT project data.
  4. Improved routines to manage parametric model data

For more details refer to the OpenSTAAD documentation

Additional Modules

The Advanced Concrete Design application, RCDC, has been updated to v11.0 which includes: –

  1. Pile Cap design added to the Australian AS 3600:2018 code.
  2. Design of Stepped and Tapered walls for Tank Design
  3. Export of rebar layout from tank designs to iModels using the iTwin Services.
  4. Improved Eurocode design support for earthquake and wind load cases.
