|Pro is a structural analysis and staad software application originally developed by Research Engineers International REI staad Pro is one of the most widely used structural analysis and staad software products worldwide, staad, staad.

It can apply more than 90 international steel, staad, staad, timber staad aluminium design codes, staad. It can make use of various forms of analysis from the traditional static analysis to more recent analysis methods like p-delta analysis, staad, geometric non-linear analysis, staad, Pushover analysis Static-Non Linear Analysis or a buckling staad. It can staad make use of staad forms of dynamic analysis methods from time history analysis to response spectrum analysis, staad.

The response spectrum analysis feature is supported for both user defined spectra as well as a number of international code specified spectra. The model geometry can even be generated from the data of macro-enabled applications like Microsoft Excel, staad, Microstation. Physical Modeling[ edit ] Physical modeling has been staad significant feature included in the program.

Staad Physical Modeler takes advantage of staad modeling to simplify modeling of a structure, staad, which in turn more accurately reflects the process of building a model. Beams and surfaces are placed in the model staad the scale of which they would appear in staad physical world. A column may span multiple floors and a surface represents an entire staad of a building, staad, staad example.

A joint is then generated anywhere two physical objects meet in the model as well staad at the free ends staad cantilevered members, staad, for convenience, staad. Operations like defining geometry, making changes in the geometric specifications are matters of only few clicks in this workflow.

It produces excellent quality plans at any level and sections in any of the orthogonal directions, staad. Beava[ edit ] The staad philosophy governing the design of bridges is that, subject to a set of staad rules and constraints, staad, the worst effects due to load application should be established and designed against, staad.

The process of load application can be complex as governing rules can staad interdependent parameters such as loaded length staad a lane, staad, lane factors, staad, staad, and load intensity. To obtain the maximum design effects, staad, engineers have to try staad loading situations on a trial and error basis, staad, staad.

This leads to the generation of many live load application staad and a large staad of output data that then must be combined with dead load and other effects, as well, staad. Bridge Deck is used to minimize the load application process while complying with national code requirements, staad, staad, staad. Pro as part staad the loading process.

An influence staad for a given effect staad a bridge staad relates staad value to movement of a unit load over the point of interest, staad.

The staad surface is a three-dimensional staad of an influence line for a single member or, in other words, it is a 2D influence function, staad. Pro will automatically generate influence surfaces for effects such as bending moments for elements, staad, staad, deflection in staad the degrees of freedom of nodes, staad, and support reactions, staad.

The user then instruct the program staad utilize the relevant influence surfaces and, staad, staad, with due regards to code requirements, optimize load positions to obtain the maximum desired effects, staad, staad.

Pro models to leverage staad power of the RCDC application. Pro environment, but requires a staad and results data from a staad analysis. Staad model should typically be formed from beams and columns plates staad currently not supported. Detailed drawings and BBS of excellent quality can staad generated as required and they are quite ready to be sent for execution, staad.

Pro environment, staad. Staad slabs can be defined, and the data can staad transferred staad RAM Concept, staad. The data passed into RAM Concept staad the geometry, staad, staad, staad and material properties, loads and staad information, and analysis results. Earthquake Mode[ edit ] Eurocode 8: Part 1 contains specific requirements and recommendations for staad structures that are to be constructed in seismic regions.

Essentially, staad, these staad requirements have been staad to ensure staad the structures can sustain the seismic loads without collapse and also — where required— avoid suffering unacceptable damage and can continue to function after an exposure to a seismic event.

Pro workflow is used to check staad the structure conforms to the basic staad recommendations made in Eurocode 8 EC8, staad. This workflow is in addition to the normal post-processing workflow which gives the various analysis results.

These checks are staad to give you a staad for the structure and are not mandatory to staad to the design phase, staad, staad, staad, staad. Through the in-built Macro Editor, one can leverage the functionalities of OpenSTAAD and automate the analysis and design workflows, staad, staad, thereby eliminating the chance of occurrence of potential errors due to manual intervention and reducing the required time for execution of the whole workflow as staad to the manual execution timeto a large extent.❷
