The resilience of cities has received worldwide attention. An accurate and rapid assessment of seismic damage, economic loss, and post-event repair time can provide an important reference for emergency rescue and post-earthquake recovery. Based on city-scale nonlinear time-history analysis (THA) and regional seismic loss prediction, a real-time city-scale time-history analysis method is proposed in this work. In this method, the actual ground motion records obtained from seismic stations are input into the building models of the earthquake-stricken area, and the nonlinear time-history analysis of these models is subsequently performed using a high-performance computing platform. The seismic damage to the buildings in the target region subjected to this earthquake is evaluated according to the analysis results. The economic loss and repair time of the earthquake-stricken areas are calculated using the engineering demand parameters obtained from the time-history analysis. A program named, "Real-time Earthquake Damage Assessment using City-scale Time-history analysis" ("RED-ACT" for short) was developed to automatically implement the above workflow. The method proposed in this work has been applied in many earthquake events, and provides a useful reference for scientific decision making for earthquake disaster relief, which is of great significance to enhancing the resilience of earthquake-stricken areas.

“…A wide variety of scientific applications are driven by advancements in high performance computing (HPC). Important examples include adverse weather forecasts, new aircraft design, earthquake simulation, radiation‐treatment planning, and evacuation in the case of the release of hazardous materials . Those real‐world applications not only involve intensive computations but also generate massive amount of data.…”

Summary Nowadays, we have entered the era of big data. In the area of high performance computing, large‐scale simulations can generate huge amounts of data with potentially critical information. However, these data are usually saved in intermediate files and are not instantly visible until advanced data analytics techniques are applied after reading all simulation data from persistent storages (eg, local disks or a parallel file system). This approach puts users in a situation where they spend long time on waiting for running simulations while not knowing the status of the running job. In this paper, we build a new computational framework to couple scientific simulations with multi‐step machine learning processes and in‐situ data visualizations. We also design a new scalable simulation‐time clustering algorithm to automatically detect fluid flow anomalies. This computational framework is built upon different software components and provides plug‐in data analysis and visualization functions over complex scientific workflows. With this advanced framework, users can monitor and get real‐time notifications of special patterns or anomalies from ongoing extreme‐scale turbulent flow simulations.

“…The development of professional and educational packages on various types of electronic platforms is an ongoing activity starting from the early days of expert systems onward, but the introduction of web‐based educational tools is more recent [11,12]. As examples, one can find diverse work ranging from that of Katsanos et al on seismic design of reinforced concrete buildings based on the Matlab platform for professional engineers, that of Sobhaninejad et al on integrated earthquake scenario simulations comprising hazard quantification, disaster quantification, and post‐earthquake recovery for use by government agencies and planners, and that of Zea et al on educational videogames for children. With respect to the field of structural mechanics, it is worth noting the work of Almeida Barretto et al on general static analysis of typical structures and structural systems and that of Romeo and Padoan on the static analysis of trusses.…”

ABSTRACT:In this work, we present a web-based educational package for teaching structural dynamics, as well as for providing an easily accessible on-line tool for interactive experimentation that is useful for both undergraduate and graduate training. Current version of the package comprises five software modules, namely (1) response history analysis of a single-degree-of-freedom system, (2) modal analysis and time history analysis of a single-storey space frame, (3) modal analysis and time history analysis of planar frames up to three stories in height, (4) generation of response spectra from ground acceleration signals, and (5) generation of synthetic ground motions for layered soil formations. These second-generation software moduli are now freely available over the internet and were derived from a previously developed educational package that has been used over the past 5 years as a virtual laboratory for teaching structural dynamics fundamentals to civil engineering undergraduates.
