NUMERICAL STUDY OF BEHAVIOR BY WALKING LOAD OF PEDESTRIAN SUSPENSION BRIDGE APPLING DIFFERENT TYPE DECKS

Abstract

 A timber deck and grating deck are often applied to pedestrian suspension bridge with a length of less than 200m and width of less than one lane. It is necessary to consider the effect of deck type on displacement of deck, the tension of the main cable and vibration characteristics. In this study, we focuse on pedestrian suspension bridge that is actually built, and consider the displacement of deck, cable tension and vibration characteristics appling timber deck, grating deck and CLT deck. As a result of analysis, timber deck has same performance as the grating deck.
