Abstract
In I-cross-section of a steel bridge subjected to tensile stress, high strength bolted friction type joints with staggered bolts arrangement are often used. Because the effective cross-sectional area can be large at the outside section of the joint by using staggered bolts arrangement. In this study, an elasto-plastic finite element analysis for high strength bolted friction joints is conducted. The analytical parameters considered in this study are the bolt arrangement, the number of bolts in a line and a row, the ratio of the design slip strength to the design yield strength. The influence that these parameters give to strength and load transferring mechanism is discussed. Furthermore the design method of high strength bolted friction type joints with staggered bolts arrangement over 8 rows of bolts in a line is considered.
