Structural Dynamics and Vibration

Structure design is a mixture of art and science, combining the experienced engineer’s intuitive feeling of statics and material. In the engineering practice, it is not exact enough to design a structure only by considering the constant loading. Time-varying loading such as earth-quake, wind loading, bomb blast loading, vortex should be taken into consideration in the practical engineer problems. If structure is subjected with a time-varying loading, the response is vibration. This article is going to show how to deal with some typical types of vibration such as free vibration analysis of SDOF equation of motion, the undamped free vibration, the damped free vibration and vibration control Further, it will explain structural dynamic responses under the periodic loading, impulsive loading. Air crash, building collapse will be predictable and this will save people’s lives and decreasing economic loss. The methodology of dynamic analysis will be applicated in the real world of structure design.
