• STRAP contains a library of standard structures that enables you to define your model by specifying a few parameters only. The library may be extended by the user.


• STRAP enables you to copy and rotate any part of the model without concern for duplicate beams and nodes as the program eliminates them automatically.


• The powerful submodeling feature of STRAP enables you to easily assemble a complex structure from its typical parts defined as submodels. Each submodel may be added at any angle at several locations of the whole model. Overlapping elements are automatically eliminated.


• A very powerful though simple to use mesh generator feature enables you to define a plane area of any shape that may also contain holes. The program will automatically create a mesh of elements taking into account the support nodes and existing elements at the contour border. 


• A section of any shape may be defined by using the CROSEC module and directly inserted into the geometry.


• Creating solid elements from existing plate elements by lifting or rotating the plate element to the nodes on the opposite face. The generated elements may have 4,5,6,7 or 8 nodes.
  
• "Wall Element" - a super element that the program internaly breaks down to its components. The wall element enables a simple and quick definition of a core / shear wall that extends the height of the building.
  
• Multiple "stages" can now be defined for a model. In each stage, beams and elements may be removed, different supports and properties may be defined,etc. Each load case may be assigned to a different stage and combinations may be defined with load cases from different stages.
