In violent earthquakes, ground motion is considered to change dramatically in the process of spatial propagation. Strong spatially varying exists near fault area, and it can cause large-span large stiffness structure be damaged. this paper, a typical long-span steel box arch bridge selected as an engineering case. order simulate variation accurately, records that sampled former earthquake are u...
When eccentric live loads are applied on the deck overhang of steel-box girder bridges, torsional moments, comprising pure and distortional moments generated box sections. The moment bridge girders distorts cross-sections, inducing additional normal stress components causing instability sections in severe cases. Hence, it is essential to install intermediate diaphragms minimize behaviors. Altho...
A significant amount of research has been conducted worldwide on the behavior of concrete filled steel tubes (CFTs) in the past five decades. This report provides a summary of the behavior and experimental work of concrete filled steel tube members, connections, and frames that are reported in detail in the literature. These published studies have been summarized with an emphasis on experimenta...
