WebSince structural damage is directly related to local deformations, a more reasonable approach for seismic evaluation and design of structures should be based on inelastic displacements rather than elastic forces. The emergence of ASCE/SEI 41-13 has laid the foundation for the development of future performance-based seismic codes. WebThe phase relationship between displacement, velocity, and acceleration is that such that velocity is 90° out of phase with acceleration and displacement is 180° out of phase with acceleration. In other words, when displacement is at a maximum, velocity is at a minimum, and acceleration is at a maximum. 20 Hz Sinusoidal Motion.
