DIY vibration testing

The two most advanced design guides on floor vibrations are SCI Publication 354 and CCIP-016 for steel-framed buildings and reinforced concrete buildings, respectively. Both design guides permit engineers to predict the response of structures due to human-induced vibrations to enable comparisons to be made with acceptance criteria contained within standards such as ISO 10137. Standards…
