摘要
介绍了拟动力抗震试验方法的特点和原理,指出误差控制是拟动力试验成败的关键。对计算误差和系统误差等误差主要来源进行了分析,模拟了试验误差传递和积累过程,并从数值积分、试验设备、试验控制等方面对抑制试验误差的方法和措施进行了探讨。
The principle and characteristic of pseudodynamic testing was presented. That the error control is the key to the success of pseudo-dynamic test was pointed out. The calculation error and system error such as a major source of error was analyzed. The process of transfer and accumulation of testing error was simulated. The error sources and error accumulation process were analyzed, and the measures to suppress test error were discussed from aspects of numerical integration, test equipment, test control and so on.
