This study analyzes descriptive statistics and tests homogeneity hypothesis, and applies a posteriori comparison procedures among treatment levels for the response characteristics such as static response ratios, impact factors, natural frequencies of bridges according to structural types and service periods. This study is expected to help understand the difference among response characteristics of groups and provides the practical information for safety assessment and structural design.
