摘要
论述了结构拟静力实验的加载规则和控制方法 ,根据目前的建筑抗震试验方法规程 ,采用力 位移混合控制的加载方法 ,基于WINDOWS NT平台和VisualC ++语言开发了拟静力加载实验控制软件TUST ,实现了力与位移控制模式的实时平滑转换。具体试件的实验验证了加载规则和控制软件的使用功能
A quasi-static test software TUST is developed. It is based on the WINDOW-NT and Visual C ++ . In TUST, it is easily switched from the force control mode to the displacement control mode during testing. The control software TUST is in consistence with the loading system developed by MTS corporation. It is coded based on the system software FlexTest, but it is still easily changed into other operating system. It is introduced in detail about the specimen type, loading rule, user interface, and software function in the paper. An example about the steel beam and frame tests is carried out to verify the software TUST.
