为了推进拟动力试验方法的研究与应用,基于NetSLab提供的通讯功能,开发了通用建筑结构远程协同拟动力试验平台NetSLab0SR.NetSLab0SR运用NetSLab所提供的通讯模式,从结构远程协同试验的角度,解决了异地计算机之间远程通讯问题,实现了操作信息的传送控制、及时反馈.采用自带的数值模拟功能和利用0penSees进行数值模拟,NetSLabOSR试验平台能够实现传统本地子结构拟动力试验和分布式远程协同子结构拟动力试验.利用NetSLab0SR试验平台,对钢管混凝土柱一钢梁组合平面和空间框架结构进行了子结构拟动力试验研究.子结构拟动力试验验证了NetSLabOSR试验平台的有效性、稳定性,且具备良好的通讯性能与试验精度.
In order to promote the research and application of pseudo dynamic test method, based on the NetSLab's communication function, a remote collaboration pseudo dynamic test platform NetSLabOSR for building structures was developed. For the remote collaboration tests, using the communication model provided by NetSLab, long distance communication among computers located in different sites was real- ized, and timely transmission and feedback of operation information was achieved. NetSLabOSR provides test capabilities for conducting the substructure pseudo dynamic tests through both traditional local method and distributed remote collaboration with numerical simulation codes developed by the authors based on OpenSees. Using NetSLabOSR test platform, substructure pseudo dynamic tests of planar and space com-posite frames with steel tube concrete columns and steel beams have been carried out, which verifies the validity and stability of the NetSLabOSR test platform, as well as the efficient communication performance and the test accuracy.
