摘要
介绍一个用于结构和构件拟动力远程协同试验的网络平台,并对测试结果进行了讨论。该网络平台名为NetSLab(NetworkedStructuralLaboratories),是基于客户机/服务器概念,并提出了供结构拟动力远程试验用的数据模型和应用协议而开发的。它能够在远程结构实验室或计算机之间通过互联网传送控制和反馈数据。在平台的开发中引入了多个新概念并采用接口引擎,从而使得应用程序界面友好、使用方便,并且用户还可以在该网络平台上作进一步自主开发。目前,在中国湖南大学和美国南加利福尼亚大学之间,采用该网络平台,通过互联网远程控制的桥柱或桩模型在地震作用下的模拟试验已经成功展开。
A network platform has been developed for remote pseudo-dynamic testing of substructures and structural elements. The network platform, NetSLab, was developed based on client/server concept along with a proposed data model and application protocols. The platform is capable of transferring control and feedback data among remote structural testing laboratories or computers connected by the Internet. Several concepts including the use of an Interface Engine are introduced to realize the platform and to provide relatively easier and friendlier interface for applications and further development by users. Trial tests were successfully carried out at the Hunan University, China and the University of Southern California, USA. In the trial tests, models simulating bridge piers or piles were subjected to recorded earthquake ground motions controlled remotely over the Internet through the platform.
