桥梁动力分析
Dynamic Vs Static problem
ESSENTIAL CHARACTERISTICS OF A DYNAMIC PROBLEM
A structural?dynamic problem differs from its static?loading counterpart in two important respects.
The first difference to be noted, by definition, is the time?varying nature of the dynamic problem-response history.
The second and more fundamental distinction between static and dynamic problems is illustrated in Fig.1
均匀质量梁的固有振动
考虑均质梁的自由振动,EI(x),m(x) 为常量EI,m。自由振动方程可以表示为:
