Stiffness of Rubber Bearings Considering Nonstandard Top and Bottom Boundary Conditions
Publisher: ASCE
Abstract: Typical installations of seismic isolation assume flexurally rigid end conditions; however, in retrofit scenarios where bearings may be placed at the tops of columns or in bridges with tall piers, some rotation may occur ...
Experimental Investigation of Elastomeric Isolation Bearings with Flexible Supporting Columns
Publisher: American Society of Civil Engineers
Abstract: In an effort to mitigate major costs associated with isolation systems, especially in retrofit applications, isolation bearings may be placed on the tops of columns. In this configuration, a seismic gap and additional rigid ...
Probabilistic Framework for Lifetime Bridge-Bearing Demands
Publisher: American Society of Civil Engineers
Abstract: The life expectancy of bridge bearings is not well understood or predicted, and bearing replacement is primarily determined through field inspection and engineering judgement. An improved estimate of the time line for ...
Parameterized Logistic Models for Bridge Inspection and Maintenance Scheduling
Publisher: ASCE
Abstract: Proper inspection and maintenance schedules are integral to bridge functionality and safety; however, they also pose challenges in light of budget and resource limitations. As such, bridge management systems (BMSs) are ...
Sliding versus Rubber Bearings: Exploring the Difference in Collapse Probability
Publisher: ASCE
Abstract: While collapse mechanisms have received significant attention for conventional buildings, they are less well understood for isolated buildings. Recently, there has been a more concerted effort to quantify the collapse ...
Fuzzy-Logistic Models for Incorporating Epistemic Uncertainty in Bridge Management Decisions
Publisher: ASCE
Abstract: Many bridge management systems (BMSs) plan future maintenance and inspection based on deterioration models derived from probabilistic analysis of field inspection data. Such analysis considers the aleatoric but not the ...
Incorporating Frame Action into Seismic Design of Gusset Plates
Publisher: ASCE
Abstract: Gusset plates connect the brace and frame in concentrically braced frames (CBFs). Failure at the interface of gusset plates with the beam or column will result in an inability to achieve energy dissipation through brace ...
