 Program Features

Main feature in analysis is that implement the 3D filer elements, which
have ever received a good reputation and many actual results in UC-win/FRAME(3D) and the plate elements based on the Reissner-Mindlin theory and also static
/ dynamic analysis are available, considering material nonlinearity and
geometric nonlinearity(Large Displacement) simultaneously.

Plate elements can have laminated structures, consists of layers which
direct to the thickness way
and define each setting for different type of materials between each layers
or linear/non/linearity.
Reinforcement concrete non linear constitutive equation is adopted as concrete
constitutive equation applied to the plate elements, which was developed
by the concrete laboratory in Tokyo University.

- Support for enlargement, reduction and move in every direction of rectangular
like 3D CAD
- Move / Rotation of elements by mouse gesture
- Easy paste of another model in an exsisting model
- Tree structure, easy to see model generating procedure
- Support for Multiple windows of model
- High advanced report output function
- powerful search function

Main screen
Engineer's Studio adopts new user interface called as "rebbon".
"Rebbon" which introduced from 2007 Microsoft Office System is
said that it will be standard in future Windows applications. It replaces
conventional "main menu" or "main tool bar" and groups
commands by functions. This makes it possible to reach your target commands
easily. This new concept have realized a user friendly operatablility for
the Engineer's Studio, which have complicated functions. Tjhe main screen
is on the right. the rebbon stands on the upper side of the screen and
trees stands on the left side.
Screen examples
<Case1>
Following image show the scene where the "View setting"tab for
Display/non-display is switched on the right side tree and the button to
display Perspective / Plane / Side / Front view are put and their views
are arranged at random on the right side screen.
<Case2>
This shows that multiple input windows of table format is arranged in one
window. Any windows can be put at the same time and rearranging is also
available like tab swithing. Add / Delete of nodes in the model by a mouse
operating reflects table automatically.
<Case3>
The Left image shows that triangle plate elements have been made by mouse
operating. Mesh division of triangle will be carried out automatically
by clicking three points in space in order and put on the "Apply"
button. The right image shows that square elements are created automatically
by dragging two point in space. Anyway, small window is used for the size
setting of mesh division or selectting element types.
<Case4>
The image shows that a window is called to search a elastic beam element.
Cross lines and a cross point are drawn on the searched element. There
are the option, which can bring the element to be "selected".
<Case5>
The deformation of plate elements and the judgement result by damage, are
displayed at the same time.
<Case6>
Setting window of report output, which do the output setting as it looks
when outputed.
Future Schedule
Followins are scheduled to..
- support for the section check for the standard based on specifications
for highway bridges and so on.
- develop the Engineer's Studio Inplane
- launch the Engineer's Studio analysis support service
