strain step

The characteristics of coseismal effect about strong motion of above seven magnitude in global and above five magnitude in China since Dec of 2004 were analyzed in this paper. When epicentral distance is little, the coseismal strain step is similar to pure phase step.

分析了2004年12月以来全球7级以上强震和中国5级以上地震的同震效应特征，当震中距较小时，同震应变阶似单纯的阶跃；

The records are stable and show that the earth strain tide and a coseismic step with earthquake on Sep.21,1999 in Taiwan had been recorded

仪器所得观测数据稳定，并记录到清晰的应变固体潮汐与台湾9.21大地震0.5μm的同震阶跃

Step-stress method is used to partition inelastic strain results from in-phase thermal-mechanical fatigue.

采用分步应力法对同相热机械疲劳产生的非弹性应变进行了区分。

In order to verify the analysis results, static test on two spatial full-sized solid models is carried out, and the step-by-step load apply system is adopted to find out the stress and strain value of each testing point.

为验证计算分析结果，对两个受力较大的铸钢节点进行了足尺实体静力试验，采用分级加卸载制度获取各级荷载下各观测点应力应变值。
