Structural Steel and Steel/Concrete Interface Details for Bridges

摘要

This report summarizes the research conducted under Task 112-D-5,4, 'Structural211u001eSteel and Steel/Concrete Interface Details'. The objective of this task is to 211u001eassess the seismic performance of details associated with steel bridge towers 211u001eextending from a massive concrete substructure to the superstructure. Issues 211u001eaddressed include: Identifying the most ductile cross-sections; Investigating the 211u001eapplication of eccentrically braced frames; Exploring details to replace buckled 211u001eplates or shapes following an earthquake; Investigating anchor bolt performance 211u001eunder lateral and uplift loads; Developing economical moment connection details 211u001ebetween steel superstructures and concrete substructures.
