The grouted splice sleeve (GSS) connection is considered to be an effective bending moment–resisting between precast RC members. This type has been used extensively in nonseismic regions. application of such a moderate or high seismic regions investigated and for multistory moment frame buildings highway bridges. A computational modeling strategy proposed at local global levels developing appropriate model using recessed GSS with intentional debonding. capable predicting the structural...
The experimental performance and numerical analysis of a hybrid two-column bridge bent was examined to evaluate its ability self-center dissipate hysteretic energy during earthquakes. experiment conducted using quasi-static cyclic loads on scaled specimen with posttensioning bars for self-centering stretch length anchors dissipation. Posttensioning were used connect the cap beam, columns, footings without any mild steel reinforcing crossing beam-to-column column-to-footing interfaces. number...
ABSTRACT Seismic performance assessment of a modified two‐column bridge bent an existing is presented. The columns the are posttensioned with high strength steel bars. combines self‐centering, from unbonded (PT) bars low initial posttensioning stress in columns, energy dissipation by replaceable external stretch length anchors (SLAs) attached at column ends. SLAs that dissipate hysteretic through tension‐only action without buckling or any significant reduction self‐centering ability. An...
