Therefore, bridge seismic problems cannot be ignored. One of the most widely used damping methods used to mitigate the seismic responses of bridges in recent

Seismic response characteristics and buckling-restrained brace-based

Subsequently, buckling-restrained braces (BRBs) were introduced to evaluate the influence of BRB force ratio on seismic mitigation performance. On this basis, an optimization design

Seismic Performance of a Novel Single and Double Spring-Based

Concentric braced frames (CBFs) are commonly used all over the world to resist seismic forces in buildings. Buckling, however, is a major concern for CBFs, in which they lose their strength

QUANTIFYING SEISMIC RESILIENCE OF SINGLE-COLUMN

Figure 1: Single-column bridge: (a) designed conventionally with the column monolithically connected with the ground (i.e. fixed-base); and (b) designed with the column-base system able to uplift and

Seismic resilience of RC bridge with self-centering energy dissipation

To enhance structural seismic resilience, the application of self-centering energy dissipation braces (SCEBs) is considered as a good solution, in particular, the damaged braces are

Performance of an innovative self-centering buckling restrained brace

The proposed SC-BRB is applied to a reinforced concrete (RC) double-column bridge pier for seismic retrofitting. Nonlinear dynamic analyses are carried out to examine its effect on the

Seismic analysis of bridge with buckling‐restrained brace

The fragility curves could be used for preliminary seismic bridge design. The analysis shows that the BRB dissipates significant seismic energy and the posttensioned concrete columns

Seismic analysis of a single span bridge according to AASHTO LRFD

Is a spill-thru abutment being used because the bridge could be lengthened in the future? If so, a seismic analysis would be needed because in the future your abutment becomes a pier.
