The analysis of structural vibration is necessary in order to calculate the natural fre- quencies of a structure, and the response to the expected excitation.
Feb 26, 2013 in the us the most commonly used method of analyzing floors for vibration is found in steel design guide #11, “floor vibrations due to human.
In the introductory chapter the causes and effects of structural vibration, the reduction and analysis are briefly outlined.
Structural vibration occurs when forces generated by machines such as compressors, pumps, chillers and air handling equipment, causes the structural steels to vibrate. Consequently, this can prompt equipment failure, noise transfer and most importantly, safety concerns. The vibration is due to the structure being mechanically resonant.
Structural vibration testing and analysis contributes to progress in many industries, including aerospace, auto-making, manufacturing, wood and paper production, power generation, defense, consumer electronics, telecommunications and transportation. This application note provides an introduction to the basic concepts of structural vibration.
Structural vibration and dynamic design analysis for fpsos, platforms, elevated structures offshore production platforms or fpsos with reciprocating or rotating machinery can experience high vibration. High vibration may cause equipment failures, lost production, excessive maintenance costs, as well as environmental and human safety issues.
Using vibration analysis and monitoring enables you to look quantitatively into structural weakness or looseness, rotating component looseness and whether resonance is present. If implemented properly, continuous vibration monitoring helps you optimize machinery performance.
Structural vibration (dynamic) analysis predicts the dynamic effects of the machinery itself so that resonance can be avoided. Dynamic loads include imbalance, misalignment, pulsation forces, cross-head guide forces, cylinder gas forces, moments, and other forces (see figure 5 for an example of dynamic forces in a reciprocating compressor).
Structural vibration analysis and damping many structures suffer from unwanted vibrations and, although careful analysis at the design stage can minimise these, the vibration levels of many structures are excessive. In this book the entire range of methods of control, both by damping and by excitation, is described in a single volume.
Structural vibration control is relevant because vibration involves dynamic strain, so that the sensing of vibration can be conducted by the sensing of strain. The elastic deformation regime is to be distinguished from the plastic deformation regime that may follow the elastic deformation regime as the stress is increased beyond the elastic limit.

Vibration analysis and structural dynamics for civil engineers: essentials and group-theoretic formulations is relevant to instances that involve significant time-varying effects, including impact and sudden movement. It explains the basic theory to undergraduate and graduate students taking courses on vibration and dynamics, and also presents an original approach for the vibration analysis of symmetric systems, for both researchers and practicing engineers.
While the analysis of a civil-engineering structure typically seeks to quantify static effects (stresses and strains), there are some aspects that require considerations of vibration and dynamic.
Vibration analysis and structural dynamics for civil engineers: essentials and group-theoretic formulations acquaints students with the fundamentals of vibration theory, informs experienced structural practitioners on simple and effective techniques for vibration modelling, and provides researchers with new directions for the development of computational vibration procedures.
