Effect of two directional loading on ductility and ultimate strength of steel bridge piers with inner cruciform walls

Publisher Summary The chapter presents the ductility and ultimate strength of steel bridge piers with inner cruciform walls subjected to two directional loading under a constant vertical load. Specimens with various radius-to-thickness ratios and slenderness ratios are used, and FEM analyses are carried out considering the effect of the loading method. Numerical analyses are carried out using a type of four-node thick-shell element in the finite element package MARC (2001). To check the validity of the numerical analyses, numerical results were compared with previous experimental results. Effects of the radius-to-thickness ratio and the slenderness ratio on the ductility and the ultimate strength of the steel bridge pier with inner cruciform walls are studied in the chapter.
