OKNO Masahiro: Study on Numerical Estmate Method for Load-Carrying Capacities of
Glued imber Laminated Bridge
・Expression of warmth and dynamic structural beauty of wood.
・Rise of needs by activation of local industry.
Thus, inside and tree structure thing to which demand as landmark is
precedingThe bounce plasticity behavior is clarified, and the thing to
request capacity is extremely important.
And so,it is orthogonalization anisotropy monotony of the laminate
lumber beam in this research in the state of a plane stress of two
And the surrender condition of Tsai-Wu which is the surrender conditional
expression of anisotropic composite materials.
The following things are examined by using the expression.
・Making of excellent laminate lumber in capacity
・A structural characteristic as the bridge material is clarified.

JIN Yingda: Research in Shape Optimization of Arch Structure
The form of arch structure, which can cover the space with huge span, has to be
designed mechanically rational. It is because of the characteristic of arch structure
that it transmits the stresses acting on it to supports by changing the forces mainly to
If we call the form of the arch as “original arch for planning”, the object of this
research is to discuss the viewpoints and the methods used on optimizing the form of
the “original arch for planning”.
In this research, we suggest the viewpoint of minimizing the elongation energy in
optimizing the form of arch. The elongation energy is set as the objective function.
The geometric characters of the arch are set as the design variables. The requests in
sizing, as well as the balance equations of forces act as constraints. Successive
Quadratic Programming(SQP) is used to solve this nonlinear optimum problem.
The circle arch with two hinges is anal
