Dynamic Structural Health Monitoring结构健康动态监测
Static deformation shows where a structure has moved. Dynamic vibration, strain, stress and pressure show how it responds to traffic, wind, machinery, water loads and sudden events — revealing frequency change, resonance, load paths and fatigue demand before they become visible damage.静态变形说明结构已经移动了多少；动态振动、应变、应力与压力则说明结构如何响应交通、风、机组、水荷载和突发事件，从而识别频率变化、共振、荷载路径与疲劳需求。

A Structure Is Not Only a Slowly Changing Shape结构不只是缓慢变化的几何形状
Bridges and dams can remain within displacement limits while their dynamic characteristics change. A shift in natural frequency, damping or operating response may indicate stiffness loss, boundary-condition change, added mass, looseness or abnormal excitation. Dynamic measurements connect these changes to actual load events.桥梁和大坝即使位移仍在限值内，动力特性也可能已经变化。自振频率、阻尼或运行响应的变化，可能对应刚度损失、边界条件变化、附加质量、连接松动或异常激励。动态测量把这些变化与真实荷载事件关联起来。
