The following new plate elements have been added:
one/two-way ribbed slabs, slabs with rectangular/round/elliptical holes, waffle slabs and Sandwich elements.
General improvement in the interface format. All icons have been redesigned.
New models: a new option (in addition to "Wizard" and "User-defined") to define a model using its grid lines.
Wall sections may now be input directly from a DXF file.
The program now solves very large models (the bandwidth limit has been removed) using an iterative method which may be much faster.
A new option to smooth all element results to eliminate local peak results caused by the finite element method.
Concrete slab drawing:
New options to display the following on the drawing:
subspace elevations, slab thickness, column sections and column names, beam sections and beam names

General improvement in the interface format. All icons have been redesigned.
A DXF file may now be created directly from any graphic display, without the current intermediate steps.
Setup: The Toolbars option has been improved and now the location of any icon in the bar may be specified.
Main screen: the number of submodels is now displayed (in addition to the number of nodes, beams, etc) |

The following new plate elements have been added:
- one-way ribbed slab (A). The ribs may be tapered.
- two-way ribbed slab (B). The ribs may be tapered and different spacing and size may be defined in each
direction.
- slab with round or elliptical holes (C).
- slab with rectangular holes (D).
- waffle slabs (E). The voids may be either rectangular or trapezoidal.
The type and orientation of the new plate elements may be displayed graphically, superimposed on the
element.
New models: a new option (in addition to "Wizard" and "User-defined") to define a grid of nodes on the default plane.
Columns: a new option to quickly define the columns in a multi-story structure
- the user first defines a list of "levels" the user than selects the base nodes of the columns; the program generate the column up to the top level
- height, creating nodes at all of the intermediate levels.
- This option combined with the previous 'grid' option, provides a powerful new tool for quickly creating highrise models.
Wall sections may now be input directly from a DXF file. The user selects the layer and the relevant section
in the file.
Walls - rigid link option:
- the links may now be specified as fixed or pinned
- the links may now be defined for selected walls only.
New options for displaying the area, weight and length of the various elements:
- section area, weight and length of each beam
- weight and length summary of each beam property
- weight and area summary of each element property
- weight of all elements for each material type
- weight and length of each wall section
- weight and volume of each individual wall.
Output format:
- The size of the section diagram superimposed on beams may now be specified.
- The size of the support symbols may now be specified (print only).
A new option when defining nodes to automatically connect them with beams.
Split beams: A new option to split beams where they intersect with other beams.
Right click on nodes: the program now displays a list of the other nodes connected to the selected node by
rigid links.
Submodels: New option to add to the main model as "individual elements" without the supports.
Elements - releases: new option to select a side to release (JA-JB, JB-JC, etc) and then select multiple
elements.

the bandwidth limit of 16,000 has been removed.
the program now solves very large models using an iterative method that is much faster.

| Results |
|
|
|
A new option to simultaneously average all element results.
- the user defines a strip width for each of the two major directions.
- for all requested element results, the program averages each result in the relevant direction, e.g. for individual element results both Mx and My are averaged, each according to the perpendicular strip width.
Element reinforcement: different cover values may now be assigned to each element property group. |

Web stiffeners: the program now computes the required vertical web stiffener spacing when d/t exceeds the code limit and assumes that the web is stiffened for all other calculations. There is an option to use the "tension field" method to reduce the shear.
Slender sections: a new option that instructs the program not to reduce the allowable stress (on the<
assumption that the designer will provide suitable horizontal web stiffeners).
The program now designs composite castellated and cellular beams. |

Beams may now be designed for axial force.
Wall sections may now be added to the slab drawings.
A new option to assign a name to every slab "subspace". The name is automatically displayed on every slab drawing.
A new option to change the level of any slab subspace.
New options to display the following on the slab drawing:
- the subspace elevations
- slab thickness
- column sections and column names
- beam sections and beam names
A new option to change the level of any beam (for beam sections on slab drawings).
A new option to select any location along the beam and to display the beam and slab cross-section at that point.
All of the new text options above may be edited - location, size, angle, etc.
User-defined text, lines and rectangles may now be added to the slab drawing.
Bar labels: the bars can now be identified on the drawing as "top" or "bottom" reinforcement.

Design according to the NBC Canada Seismic provisions has bee updated according to the 2005 version.
Update STRAP results file:
- the default dynamic load case names may now be revised.
- a warning is now displayed if a case is created with the same name as an existing case.
The Story results option has been improved:
- mass and rigidity centers are now calculated for stories without rigid links.
- a table of "Story shear forces" may now be displayed and printed.
- the floor mass (weight) is now displayed in the story calculation table.
- User defined drift limits may now be specified for all Codes.
The Modal results table has been improved:
- the modal seismic coefficient, Fn/Wn, is now displayed.
- units are now displayed for Fn, Qn, Vn, An
Weights: the sum of the defined weights is now shown on the graphic display.

The user may now identify a slab area in which identical cables at constant spacing may be defined. The area does not have to be rectangular; the program adjusts the length of individual cables accordingly. A results envelope for all of the cables in the area is displayed.
An option has been added to automatically define the cable trajectory according to the moment envelope. The user specifies the vertical cable location and the straight segments at the points of maximum and
minimum moment. The automatic trajectory may be modified by the user.
The cable trajectory may now be imported from a DXF drawing.
An option to reduce the slab moments adjacent to columns has been added.
The ducts of existing perpendicular cables may now be displayed when defining a new cable in order to prevent conflicts.
New options have been added to the cable definition dialog box:
- the cable list may now be rearranged
- selected cables may now be removed from the beam elevation display.
