Analytical model can be created using the ribbon-based user interface, by editing the command file or by importing several other files types like dxf, cis/2 etc. The model geometry can even be generated from the data of macro-enabled applications (like Microsoft Excel, MicroStation etc.) by using Macros.
Physical modeling has been a significant feature included in the program. STAAD.Pro Physical Modeler takes advantage of physical modeling to simplify modeling of a structure, which in turn more accurately reflects the process of building a model. Beams and surfaces are placed in the model on the scale of which they would appear in the physical world. A column may span multiple floors and a surface represents an entire floor of a building, for example. A joint is then generated anywhere two physical objects meet in the model (as well as at the free ends of cantilevered members, for convenience).
STAAD Building Planner
STAAD Building Planner is a module that enables seamless generation of building models that can be analyzed and designed thereafter in the program itself. Operations like defining geometry, making changes in the geometric specifications are matters of only few clicks in this workflow.
Steel AutoDrafter workflow extracts planar drawings and material take-off from a structural steel model prepared in STAAD.Pro. It produces excellent quality plans at any level and sections in any of the orthogonal directions.
The general philosophy governing the design of bridges is that, subject to a set of loading rules and constraints, the worst effects due to load application should be established and designed against. The process of load application can be complex as governing rules can impose interdependent parameters such as loaded length on a lane, lane factors, and load intensity. To obtain the maximum design effects, engineers have to try many loading situations on a trial and error basis.
This leads to the generation of many live load application instances (and a large volume of output data) that then must be combined with dead load and other effects, as well. Bridge Deck is used to minimize the load application process while complying with national code requirements.
The program is based on the use of influence surfaces, which are generated by STAAD.Pro as part of the loading process. An influence surface for a given effect on a bridge deck relates its value to movement of a unit load over the point of interest. The influence surface is a three-dimensional form 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, deflection in all the degrees of freedom of nodes, and support reactions. The user then instruct the program to utilize the relevant influence surfaces and, with due regards to code requirements, optimize load positions to obtain the maximum desired effects.
