RISSeismic Performance Assessment of Masonry Tile Domes through Nonlinear Finite-Element Analysis
Publisher: American Society of Civil Engineers
Abstract: This article discusses a combined analytical and experimental study on the nonlinear seismic performance of two Guastavino-style masonry domes located in the United States. The seismic performance of these masonry domes ...
Fidelity and Robustness of Detailed Micromodeling, Simplified Micromodeling, and Macromodeling Techniques for a Masonry Dome
Publisher: American Society of Civil Engineers
Abstract: Understanding the damage and failure mechanisms of masonry structures can help engineers reduce catastrophic failures and facilitate effective restoration and preservation of historical masonry monuments. This can be ...
Optimization-Based Strong Coupling Procedure for Partitioned Analysis
Publisher: American Society of Civil Engineers
Abstract: The concept of partitioning a complex engineering problem into smaller, manageable components and investigating each individual component autonomously has been in use for many decades. Such partitioning approaches, however, ...
Error and Uncertainty Analysis of Inexact and Imprecise Computer Models
Publisher: American Society of Civil Engineers
Abstract: Computer simulations are routinely executed to predict the behavior of complex systems in many fields of engineering and science. These computer-aided predictions involve the theoretical foundation, numerical modeling, and ...
Partitioned Analysis of Coupled Numerical Models Considering Imprecise Parameters and Inexact Models
Publisher: American Society of Civil Engineers
Abstract: The present study develops an integrated coupling and uncertainty quantification framework for strongly coupled models that explicitly considers the propagation of uncertainty and bias inherent in model prediction between ...
Selection of Optimal Sensor Locations Based on Modified Effective Independence Method: Case Study on a Gothic Revival Cathedral
Publisher: American Society of Civil Engineers
Abstract: This study demonstrates a methodology for selecting optimal regions for placing vibration sensors to efficiently extract the dynamic characteristics of the nave of the Cathedral of St. John the Divine (SJD). Placing sensors ...
Assessment of Strength Degradation of Historic Masonry Monuments due to Damage: Load Path–Based Approach
Publisher: American Society of Civil Engineers
Abstract: Historic masonry monuments experience aging and accumulated damage, which consequently degrade both their stiffness and strength. Stiffness degradation can be quantified through nondestructive testing and has been widely ...
Bootstrapping for Characterizing the Effect of Uncertainty in Sample Statistics for Braced Excavations
Publisher: American Society of Civil Engineers
Abstract: A simple procedure for assessing the probability of serviceability failure in a braced excavation involving bootstrapping to characterize the effect of uncertainty in sample statistics is presented. Here, the failure is ...
Sustainability Analysis of a Leakage-Monitoring Technique for Water Pipeline Networks
Publisher: ASCE
Abstract: Water infrastructure plays a crucial role in delivering freshwater for survival and economic prosperity of communities. Regrettably, drinking water pipeline infrastructures in the US and many other developed and developing ...
Influence of Soil Backfill on Vibration-Based Pipeline Leakage Detection
Publisher: ASCE
Abstract: An estimated 20% of treated fresh water is lost through leakage in distribution pipeline infrastructure in the United States. As a result, significant research has been devoted to developing technologies that will assist ...
