The results show that the main factors influenced structural earthquake are earth damage degree , fault length stress and an angle between extend stress axes and fault strike 研究结果表明，地壳损伤程度、断层长度、应力及拉应力轴与断层走向之间的夹角是影响构造地震的主要因素。
This paper have identifications to the whole bridge with genetic algorithm , the data indicate that the method to identify the damages of the double arch is precise 论文通过遗传算法对全桥损伤(包括损伤位置和损伤程度)进行识别，结果表明遗传算法对双曲拱桥的主要病害识别有较好的精度。
Bottom of the screen said of the long car injury , after all into a yellow vehicle will be completely destroyed , meanwhile the end of the game , according to adhere to the 画面下方的长条表示汽车的损伤程度，全部变为黄色以后车辆就会彻底毁坏，同时游戏结束，依据玩家坚持的时间来给出最后得分。
Through processing vibration signal of the damaged blade , it can be seen that the different depth and location splits have the different influences to the vibration character of the blade 通过小波分析处理不同损伤程度的叶片振动信号，总结分析了不同深度和位置的裂纹对叶片振动特性的影响。
This model will be more coincidence with the real structure . 2 . present the conception and calculate method of blow - up degree of the peak based on the peak of strain mode curve diagram 5建立了实际工程的有限元模型,进行损伤位置与损伤程度的识别,验证本文的方法在实际工程中的可行性和准确性。
In the future work through comparing the detail signal from damage specimen with the signal from healthy specimen , the damage signature can be extracted 在将来的工作中，通过比较复合材料损伤信号和无损伤信号的细节信号的差异，提取同损伤相联系的特征，就能进行材料损伤位置及损伤程度等判定工作。
After the localization of the damage , the extent of the damage can be determined according to the relation between the damage extent with the change rate of natural frequencies before and after damage 损伤位置确定后，利用板在这一位置的损伤程度与板损伤前后的频率变化率的关系，可以确定损伤的程度。
Five sets of long - term axial loading equipment were designed and manufactured . the component of long - term loading test comprised axial creep and creep recovery at two different level of sustained load 试验中,获取了不同损伤程度加固柱在长期荷载作用下的试验数据,同时考虑了不同大小轴压荷载的影响。
So the occurrence ^ location and degree of the damage can be identified in theory , according to the differences of modal parameter between damaged and undamaged structure 结构中不同位置的损伤对结构各阶模态的影响不同，因而根据结构损伤前后模态参数的变化在理论上可以确定损伤的发生与否及其位置和损伤程度。
4 . using processed frequencies and first order modal dofs in a few points as network inputs , trained neural network gives excellent assessment results of a steel truss bridge 4 、本文以结构的低阶频率和少数节点的一阶振型分量，经预处理后作为神经网络输入，准确实现了对一钢析粱桥的损伤位置和损伤程度识别。
