Recently, the concern of the aspect of esthetic value that the shape of a bridge itself has and the aspect of landscape from harmony with surrounding environment. This is different tendency with before that emphasize the aspect of functional and structural safety. Because a bridge is important structure to determine urban landscape and one of the landmark, so it needs to evaluate bridge's design and bridgescape.
The aim of this study is to investigate the present state of the whole country's bridge and to evaluate the visual perception against bridgescape employing semantic differential method through 16 adjectives. And it also analyzes the preference of day and night landscape and the remarkable landmark out of 8 bridges to represent Pusan through Delphi technique, and analyze the similarity on the assessment of bridge's shape, color, light, harmony with the environment which are each bridge's bridgescape composition employing multidimensional scaling method.
The major findings of this paper are as follows;
First, it is the best factor to determine bridgescape that is the harmony with environment and the shape of bridge. So the result of analysis the evaluation on the visual perception according to the shape of bridge through 16 adjectives, the most unique bridge is arch bridge, the most common bridge is steel box girder bridge, the most familiar bridge is suspension bridge, the most unfamiliar bridge is rigid-frame bridge. Cable-stayed girder bridge give us the most active sense, prestressed concrete slab bridge give us the most static sense. The most rhythmical bridge is rigid-frame bridge, the most monotonous bridge is prestressed concrete slab bridge, and cable-stayed girder bridge give us the strongest impression and the most cheerful feelings.
The factor analysis summarize from 16 adjectives to 3 factors. the first factor is commonness which is organized by boring, unbeautiful, unfashionable, monotonous, uninteresting, static, common, simple, depressed, the second factor is disharmony which is composited by reluctant, bad, uneasy, discontinuous, weak, discomfortable, the third factor is unfamiliarity.
Second, the bridge which represent Pusan recognized which has the splendid day and night landscape and landmark. Gwangan Bridge is evaluated as chosen the best bridge which has landscape and is the supremacy landmark to represent Pusan. But the result on the assessment for each bridgescape compositions shows interesting findings. Pusan Bridge and Shinho Bridge is bound to the same group as an arch bridge in the bridge's shape aspect and red color which are made of steel in the bridge's color aspect. And Pusan Bridge is similar to Gupo Bridge in the bridge's illumination aspect. The Second Nakdong Bridge and the Third Nakdong Bridge are the lowest grade in all items.
Gwangan Bridge is the best bridge and cannot compare with others in the day and night landscape and landmark, as well as bridgescape composition which include bridge's shape, color, illumination and harmony with environment. On the other hand, in spite of Yongdo Bridge's symbol, the assessment shows a bad valuation on the old bridge by a low grade at bridgescape composition
