RISDeflection Control of Long-Span PSC Box-Girder Bridge Based on Field Monitoring and Probabilistic FEA
Publisher: American Society of Civil Engineers
Abstract: For long-span prestressed concrete (PSC) box-girder bridges, excessive midspan deflection because of uncertain concrete shrinkage and creep undermines driving comfort and structural safety. In this paper, a deflection ...
Effect of Semiactive Control on Wind and Seismic Responses of High-Rise Building Supported on Triple Friction Pendulums
Publisher: ASCE
Abstract: A triple friction pendulum bearing (TFPB) as an isolator has been considered more competitive than conventional bearings such as rubber bearings or single friction pendulum bearings due to its versatile behaviors under ...
Pavement Rehabilitation Strategy Selection for Steel Suspension Bridges Based on Probabilistic Life-Cycle Cost Analysis
Publisher: American Society of Civil Engineers
Abstract: Field inspections on long-span steel suspension bridges in China reveal that the pavements undergo a fast deterioration process attributed to the flexibility of suspension bridges and the heavy traffic loads. Such extensive ...
Seismic Fragility Evaluation of SCCB-Enhanced RC Frame Structures
Publisher: ASCE
Abstract: A novel self-centering cable brace (SCCB) with friction devices was developed to improve the seismic performance of existing frame structures. To investigate the enhancing effect of the SCCB on reinforced concrete (RC) ...
Investigation of Fatigue Behavior of Steel and GFRP Double-Strap Joints under Varied Cyclic Loading at Given Temperatures
Publisher: ASCE
Abstract: This paper examines the fatigue behavior of steel/glass fiber reinforced polymer (GFRP) double-strap joints under a variation of cyclic shear loading at different given temperatures. Initial experiments were performed at ...
Experimental Study on Corrosion-Fretting Fatigue Behavior of Bridge Cable Wires
Publisher: ASCE
Abstract: Bridge cables are often subjected to tensile stress variation, interior contact stress, and corrosion environment, resulting in premature failure of wires. This paper experimentally investigates the behavior of bridge wires ...
Multiscale Modeling and Seismic Fragility Analysis of Corroded Precast Concrete Frame
Publisher: ASCE
Abstract: Precast concrete frames have been widely used, though little is known about their fragility under the combined influence of seismic excitation and corrosion. In this study, one four-story precast concrete frame with different ...
Stability Analysis of Real-Time Hybrid Simulation with Time-Varying Delay through a Delay Decomposition Approach
Publisher: ASCE
Abstract: Stability of real-time hybrid simulation (RTHS) has attracted considerable attention given that actuator delay might destabilize the real-time test, especially when the compensation is not sufficient. Previous research by ...
Reliability-Based Maintenance Strategy for Gusset Plate Connections in Steel Bridges Based on Life-Cost Optimization
Publisher: ASCE
Abstract: This paper focuses on the maintenance decision of vulnerable parts that need rehabilitating within the design service period under repetitive vehicular loads in steel bridges based on the time-variant performance deterioration ...
Shake-Table Tests and Numerical Analysis of Steel Frames with Self-Centering Viscous-Hysteretic Devices under the Mainshock–Aftershock Sequences
Publisher: ASCE
Abstract: Shake-table tests, subjected to mainshock–aftershock sequences, were conducted on a 1/3-scaled 3-story steel frame equipped with self-centering viscous-hysteretic devices (SC-VHDs) and its primary frame to investigate the ...
