RISFEM-BEM Modeling of Dynamic Responses of a Fluid-Filled Lined Tunnel under a Water Hammer
Publisher: American Society of Civil Engineers
Abstract: A frequency-domain finite element method and boundary element method (FEM-BEM) coupled numerical method is presented to investigate the dynamic responses of a fluid-filled lined tunnel buried in the ground. The fluid is ...
Time-Based Toll Design for a Cordon-Based Congestion Pricing Scheme for a Transportation Network with Speed Limits and Movement Prohibitions
Publisher: American Society of Civil Engineers
Abstract: In the central business district (CBD) of metropolises, speed limits and movement prohibitions are often imposed on roads and intersections, respectively, for the purpose of safety and congestion mitigation and sometimes ...
Structural Reliability Analysis Including Correlated Random Variables Based on Third-Moment Transformation
Publisher: American Society of Civil Engineers
Abstract: In structural reliability analysis, the input variables are often nonnormal and correlated. A procedure for efficient normal transformation, i.e., transforming dependent nonnormal random variables into independent ...
Seismic Performance of Precast Prestressed Concrete Bridge Girders Using Field-Cast Ultrahigh-Performance Concrete Connections
Publisher: American Society of Civil Engineers
Abstract: Precast concrete bridges have many advantages over cast-in-place construction. Prefabrication typically requires less time at the site due to the ease of installation. Furthermore, production in a controlled environment ...
Seismic Response of Single Pylon Cable-Stayed Bridge under Scour Effect
Publisher: American Society of Civil Engineers
Abstract: For a bridge located in a seismically active and flood-prone region, the occurrence of earthquakes combined with flood-induced scour is a highly possible multihazard event. This study quantifies the scour effect on the ...

Time-Dependent Structural Reliability Assessment for Nonstationary Non-Gaussian Performance Functions
Publisher: ASCE
Abstract: In this paper, a new analytical formula is proposed to determine the mean outcrossing rate of nonstationary non-Gaussian performance functions. The performance function is firstly transformed into a standard Gaussian process ...
Moment Method with Box–Cox Transformation for Structural Reliability
Publisher: ASCE
Abstract: Structural reliability analysis involving highly nonnormally distributed performance functions or relatively small failure probabilities is still a challenging problem in engineering practice. To overcome these problems, ...
