Engineer's Studio(R) for Students is a 3D FEM analysis program that has
been developed completely in-house. It includes preprocessing, calculation
engine and post processing (Figure1/2). Civil and Architectural structures
can be modeled with a variety of element types. Static and dynamic analysis
can be undertaken. In addition, there is a wide range of material nonlinear
element types and specific models within each element type.

Both material nonlinear and geometrical nonlinear (large displacement analysis)
analyses are possible and these two effects can be modeled simultaneously.
Fiber elements are supported. This is the element type that was used in
the blind analysis contest (Note1). Mindlin plate elements are supported
and in addition to material linear analysis the Maekawa nonlinear constitutive
law of reinforced concrete (distributed crack model) developed in the concrete
laboratory of Tokyo University is supported.
Design features are also included and the student can gain experience in
design including influence line analysis (for live load), reinforcing level
checks, allowable stress calculations and ultimate strength checks for
both shear and flexural actions.
Note1) The analysis result of "Engineer's Studio(R)" won the E-Defense
Pre-analysis Contest of Full scale RC Pier Earthquake Resistance Experiment!
