摘要
在数据采集系统的电路原理基础上,将其应用于地震模拟振动台试验中,并根据需要制作了传感器的转接元件,验证了其可靠性。对不同结构的剪切墙进行了模态试验,在试验方法上采用数字迭代反馈技术,精确再现了地震波,通过试验对结构自振频率、水平和垂直加速度反应等进行了研究。对采集的数据进行了处理和分析,经过对比证明剪切墙加固方法设计的合理性。
An application of Data acquisition system in shaking table tests for the seismic simulation were research in the paper based on circuitous philosophy. Switching elements of sensors were made and worked normally. Modal testing were presented on shear walls with kinds of structure. The digital compensation feedback method was used for reproducing earthquake waves, the natural vibration frequency, the horizontal and vertical accelerationresponse were studied. By data analyzing and processing and camparising the test results, the strengthening method on shear walls were proved correct.
