RISRedundancy in Residual Vectors for Missing Mass Effect in Coupled Modal Synthesis
Publisher: American Society of Civil Engineers
Abstract: It has been illustrated in the past that a modal synthesis gives incorrect modal properties and seismic response of nonclassically damped coupled systems when all the modes of uncoupled primary and secondary systems are ...
Modeling the Dynamic Behavior of Electrical Cabinets and Control Panels: Experimental and Analytical Results
Publisher: American Society of Civil Engineers
Abstract: Ritz vector approach for evaluating the dynamic properties of electrical cabinets is based on the premise that a single significant cabinet mode is sufficient to calculate accurate incabinet spectra needed in the seismic ...
Missing Mass Effect in Coupled Analysis. I: Complex Modal Properties
Publisher: American Society of Civil Engineers
Abstract: New formulations are developed to account for the effect of uncalculated high frequency rigid modes in the seismic analysis of coupled primary–secondary systems by modal synthesis approach. The effect of uncalculated rigid ...
Missing Mass Effect in Coupled Analysis. II: Residual Response
Publisher: American Society of Civil Engineers
Abstract: This is the second paper of two papers that describe the procedures to include the effect of uncalculated high frequency modes in coupled modal synthesis. Because the residual modal vectors of a multiply supported secondary ...
Internet-Enabled Remote Observation and Control of a Shake Table Experiment
Publisher: American Society of Civil Engineers
Abstract: This paper describes a computational framework and the corresponding interfaces required to convert a shake table experiment for remote access including control, observation, and protection from misuse. The laboratory ...
A Multilevel Adaptive Mesh Scheme for Efficient Simulation of Thermomechanical Phase-Field Fracture
Publisher: American Society of Civil Engineers
Abstract: The numerical modeling of thermomechanical fracture is an essential aspect of designing critical components in various industries, including aerospace, automobile, and nuclear. The phase-field method is a suitable approach ...
Integrated 4D Design Change Management Model for Construction Projects
Publisher: ASCE
Abstract: Managing design changes effectively can reduce cost overruns and schedule delays in construction projects. However, existing design change management in construction projects lacks integration with schedules, comprehensive ...
Application of Risk-Informed Validation Framework to a Flooding Scenario
Publisher: ASCE
Abstract: In recent years, the use of advanced simulation tools for modeling the behavior of flooding at a nuclear power plant has gained significant importance. The credibility of advanced simulation codes is assessed using formal ...
Genetic Algorithm-Based Decision Support for Optimizing Seismic Response of Piping Systems
Publisher: American Society of Civil Engineers
Abstract: This paper describes computational approaches used in a prototype decision support system (DSS) for seismic design and performance evaluation of piping supports. The DSS is primarily based on a genetic algorithm (GA) that ...
