摘要：Live load distribution factors are used to determine the live-load moment for bridge girder design when a two-dimensional analysis is conducted. A simple, analysis of bridge superstructures is considered to determine liveload factors that can be used to analyse different types of bridges. The distribution of the live load factors distributes the effect of loads transversely across the width of the bridge superstructure by proportioning the design lanes to individual girders through the distribution factors. This research study consists of the determination of live load distribution factors (LLDFs) in both interior and exterior girders for horizontally curved concrete box girder bridges that have central angles, with one span exceeding 34 degrees. This study has been done based on real geometry of bridges designed by a company for different locations. The goal of using real geometry is to achieve more realistic, accurate, and practical results.
