【摘要】：结构抗震试验在结构工程与地震工程领域占有非常重要的地位。混合试验作为抗震试验的重要分支，与其他抗震试验方法相比有着明显优点。它将物理实验与数值模拟相结合，对试验子结构进行静力加载，大大降低了对加载系统的要求，能够进行大尺度的模型试验。如今，，互联网通信技术的发展又为混合试验带来了新的发展方向——分布式混合试验。分布式混合试验是将处于异地的结构实验室通过网络连接起来，形成一个“网络实验室”共同完成混合试验。通过这种方式不仅能完成单个实验室不能完成的大型的、复杂的结构试验，还减少了对试验设备的重复投资，降低花费。为了推进混合试验方法的研究与应用，哈尔滨工业大学吴斌教授课题组开发了一个混合试验平台，即HyTest。本文在现有的HyTest试验软件的基础上，进一步开发其混合试验功能。本文主要内容及结论如下：（1）HyTest混合试验平台的MTS控制系统通信模块的开发：在Visual Basic6.0环境下，采用MTS提供的VB软件接口开发了HyTest试验平台与MTS控制系统的通信模块，其具备模拟试件、保存参数、读取参数及输出数据的功能。完成了一个单层单跨平面钢框架结构混合试验，验证了该通信模块的有效性。（2）HyTest混合试验平台分布式混合试验功能的开发：利用C++网络编程开发了HyTest基于云中转服务器的通信架构，解决了HyTest分布式混合试验的网络通信问题，完善了HyTest相关界面，开发了HyTest的分布式混合试验功能。（3）完成了某6层5跨平面钢框架结构基于HyTest的混合试验模拟：将HyTest的时程分析结果与OpenSEES动力分析的结果进行对比，验证了MTS通信模块进行模拟试件的有效性以及HyTest的分布式混合试验功能。在不同网络状况下，利用HyTest分布式混合试验功能进行该模拟试验，对HyTest程序的运行速度及网络通信速度进行测试，验证了HyTest基于云服务器的数据中转的可行性以及HyTest混合试验平台的稳定性。
[Abstract]:Structural seismic test plays an important role in the field of structural engineering and seismic engineering. As an important branch of seismic test, hybrid test has obvious advantages compared with other seismic test methods. It combines the physical experiment with the numerical simulation, carries on the static load to the test substructure, greatly reduces the requirement to the loading system, and can carry on the large-scale model test. Today, the development of Internet communication technology has brought a new direction for hybrid testing-distributed hybrid testing. The distributed hybrid experiment is to connect the structure laboratory in the different place through the network, and form a "network laboratory" to complete the mixed experiment together. In this way, not only large and complex structural tests that can not be completed in a single laboratory can be completed, but also repeated investment in test equipment and cost can be reduced. In order to promote the research and application of hybrid test methods, the research group of Professor Wu Bin of Harbin University of Technology developed a hybrid test platform, HyTest. com. In this paper, based on the existing HyTest test software, the hybrid test function is further developed. The main contents and conclusions of this paper are as follows: The development of communication module of MTS control system of hybrid test platform: in Visual Basic6.0 environment, the communication module between HyTest test platform and MTS control system is developed by using VB software interface provided by MTS. The function of reading parameters and outputting data. A single layer single span plane steel frame structure mixed test was completed, and the validity of the communication module was verified. The development of the function of distributed hybrid test on the hybrid test platform: the communication architecture of HyTest based on cloud transfer server is developed by using C network programming, the network communication problem of HyTest distributed mixed test is solved, and the related interface of HyTest is perfected. The distributed mixed test function of HyTest is developed. In this paper, the hybrid test simulation of a six-story five-span steel frame structure based on HyTest is completed. The time history analysis results of HyTest are compared with those of OpenSEES dynamic analysis. The effectiveness of the MTS communication module for simulating the specimen and the distributed hybrid test function of HyTest are verified. Under different network conditions, the HyTest distributed hybrid test function is used to carry out the simulation test, and the running speed and network communication speed of the HyTest program are tested. The feasibility of HyTest data transfer based on cloud server and the stability of HyTest hybrid test platform are verified.
