Abstract: Various semiactive systems have been proposed to control the seismic response of civil structures. These include semiactive fluid, friction, and stiffness devices. Energy dissipation in these devices occurs through a variety ...

Abstract: Adjacent precast prestressed concrete box-beam bridges have been used in the United States for many years and have performed well. However, the shear keys between adjacent box beams are susceptible to cracking, which can ...

Abstract: Protecting critical equipment in seismically excited buildings is essential to ensure functionality after an earthquake. Individual equipment or equipment sets can be seismically isolated from the building motion. Special ...

Abstract: In this study, the live-load moment-distribution factors (LLMDFs) were evaluated for an adjacent precast prestressed concrete box beam bridge. The bridge used a new shear key configuration, which was grouted with ultrahigh ...

Abstract: Recent research on ultrahigh-performance concrete (UHPC) for connection elements in highway bridges indicates an improvement in the performance of the overall bridge superstructure. However, there is limited information ...

Abstract: The interaction of wind with elastic structures is complex. It is impossible to describe both wind and structural motion without considering the interaction therein. The purpose of this technical note is to present a method ...

Abstract: Recently, there has been a rapid increase in using ultrahigh-performance concrete (UHPC) in bridge connections due to its high compressive strength, pre- and postcracking tensile strengths, superior bond, and durability ...

Abstract: The outstanding mechanical and bond strength properties of ultrahigh-performance concrete (UHPC), as well as its long-term durability, make it a suitable material to be used in connections of accelerated bridge construction ...
