Modified Best-Selection Method for Bridge Live-Load Model Development
Publisher: ASCE
Abstract: Due to the expanding availability of high-fidelity weigh-in-motion (WIM) data in recent years, various local agencies have modified bridge design and rating procedures to best reflect state-specific traffic loads. However, ...
Development of Traffic Live-Load Models for Bridge Superstructure Rating with RBDO and Best Selection Approach
Publisher: American Society of Civil Engineers
Abstract: Reliability-based design optimization (RBDO) is frequently used to determine optimal structural geometry and material characteristics that can best meet performance goals while considering uncertainties. In this study, the ...
Load Truncation Approach for Development of Live-Load Factors for Bridge Rating
Publisher: ASCE
Abstract: Various local governments have developed state-specific vehicular live-load factors for bridge rating. However, a significant computational demand is often associated with such an effort. This is due to the large size of ...
Long-Term Durability of FRP Bond in the Midwest United States for Externally Strengthened Bridge Components
Publisher: American Society of Civil Engineers
Abstract: In this study, the bond strength of a typical FRP system subjected to long-term natural weathering in the midwest United States is experimentally investigated, and the rate of degradation is estimated. To do this, the bond ...
