已在实地开发和安装了许多结构监测系统，以收集有关土木工程结构和系统（如建筑物和桥梁）的性能和行为的资料。处理和分析从连续监测系统收集的大型数据集通常需要大量的时间和精力。为了加快对这些连续监测数据的处理速度，便于更快速地分析数据，更及时地解释和使用结果，开发了一个涵盖数据处理各方面的实时数据处理分析应用平台。该应用平台由数据处理、分析和可视化模块组成，所有模块都通过图形用户界面（gui）集成。由于网络速度的限制，应用程序被设计并适应在实时模式下运行，通过自动分类传入数据并将其重新定向到处理和动画模块，以便在接近实时的情况下图形显示桥梁位移和运动。有了这种能力，在发生极端事件（如风暴、地震或船舶撞击）后，可以及时评估桥梁反应和设施状况，为其运行提供决策支持。通过对最近研究成果的讨论，可以说明利用本文中提出的计算机工具应用程序可以探索的研究机会。
Numerous structural monitoring systems have been developed and installed in the field to collect information on the performance and behaviour of civil engineering structures and systems, such as buildings and bridges. The processing and analysis of large datasets collected from continuous monitoring systems often require a significant amount of time and effort. In order to accelerate the processing of these continuous monitoring data and to facilitate more rapid data analysis, and more timely interpretation and use of the results, a real-time data processing and analysis application platform has been developed which encompasses all aspects of data manipulation. This application platform consists of data processing, analysis and visualization modules, all integrated through graphical user interfaces (GUIs). The applications are designed and adapted to run in a real-time mode by automatically sorting incoming data and re-directing it to the processing and animation modules for graphic display of bridge displacements and motion in near real-time, as limited by the network speed. With this capability, after the occurrence of extreme events such as windstorms, earthquakes or ship impacts, bridge responses and condition of the facility can be assessed in a timely manner for decision support of its operation. The research opportunities that can be explored using the computer tool applications presented in this paper are illustrated by a discussion of recent research results.
