  • Seismic performance evaluation systems require rational classification of structure systems, proper evaluation criteria, and their scoring index for synthesis. Current seismic performance systems need expert judgments based on collection of available data, approximate analysis of important items, and various scoring system. This study presents a three-step seismic performance evaluation system for building structures in Korea. Each evaluation step determines the seismic performance and the method depends on the degree of refinement of analysis. The preliminary step evaluation involves the global attributes of structures such as vertical irregularity, asymmetric plan, redundancy, and age of structures. The second step requires an elastic analysis for estimation of forces acting on critical sections and checks the strength and ductility. The final step requires inelastic capacity of structures. Each stephas own evaluation scheme with proper weighing factor dependent on the importance and consequence. This study applies the fuzzy theory to a scoring method that synthesizes the individual quantity to a representative value.

  • In this paper data of index is acquired by some experts. Then the ambipolar models of Fussy Synthesis Evaluation theory is adopted in this paper which helps to the synthesis analysis of the Aids to Navigation in DaLian port area. At the same time, in accordance with the suggestion of the experts and the real condition, the idiographic implement way is mentioned in the point of view of Quality. The two points of view make the scheme more scientific and feasible. After achieving the status, the project scheme of synthetical alteration to Aids to Navigation in DaLian port area is put forward. It arranges the improved ideas from the different point of view of content, efficiency expectation of Aids to Navigation which gives the reference of the alteration and development of the Aid to Navigation which gives the reference of the alteration and development of the Aids to Navigation in DaLian port area for the future.
