This study investigates the geodesic dome based on an icosahedron and development of joint modules that make up a dome structure in order to model the modular dome using the wood-plastic composite member with 70% of wooden fiber contests. The purpose of this work is used as a basis for verification of structural performance of WPC in the real structures.

This paper aimed at modeling a triangular mesh for triangular grid dome by using improved harmony search algorithm. For this purpose, an optimization process to find a regular triangular mesh on the curved surface was proposed and a program for this was developed. The objective function consisted of the standard deviations of the area and the boundary length of each triangle, and the design variables were regulated by the upper and lower boundary conditions which were calculated depending on the nodal connectivity. Triangular grid dome, which initially had consisted of irregular triangular meshes, was selected as target example. In dome model, its result was very approached to the minimum standard deviation of the area and the boundary length of each triangle.

A cable structures have the advantage that cover a large space without column but it is very sensitive to deal with shape control because of its flexibility. Especially, location of control member and needed elongation of member are important things. Therefore, the purpose of this paper is studied on displacement control technique for pre-stressed cable structures by force method considering order of control.

In the past spatial structures have been significantly developing in the architectural field. Most of all, the single layer grid dome has become very popular, having not only with aesthetic advantages, but also the economic benefit of saving material. Especially, a generation of triangular mesh for the curved surface is one of the important things. Therefore, in this paper, a generation technique to get a equilateral triangle surface of single layer dome is deal with. To solve the problem, the objective function is consist of the standard deviation of triangular element and differential evolution method is adopted to fine a fine triangular gird.

To evaluate the deformation of space frame dome structure in Daegu Athletic Center, horizontal displacements of all 32 supports and vertical deflections at 8 points are predicted through the elastic analysis. The result of a comparison with the measurement data shows that the analysis well predicts the measured horizontal displacements and vertical deflections

Construction period is one of the most important factors which influence on cost and quality in nuclear power plant construction. As part of continued efforts for the competent reactor type, a dome liner plate module in the reactor containment building is developed to minimize the construction period. This study referred to knowledge and experiences from APR+(Advanced Power Reactor Plus) technical development. The proposed method can be applied to the APR+ in the near future.
