One of the most important factors on bridge safety is the load model. Especially it is urgently needed to develop live and fatigue load model based on the reliability theory to adopt Load and Resistance Factor Design method. The purpose of the study is to develop the live and fatigue load model based on the current situation. To do this, in the first year, Various methods to develop the load model were analyzed and applicability was examined, various truck weight data are collected and their characteristics are analyzed. To determine the characteristics of multiple trucks, video recording was done and analyzed. To calculate the fatigue damage accumulation, procedures for determining the load cycle numbers are examined and specifications of fatigue design from various countries were analyzed.
