An Impulse and Earthquake Energy Balance Approach in Nonlinear Structural Dynamics
- Available for pre-order. Item will ship after March 10, 2021
Problems in nonlinear structural dynamics and critical excitation with elastic-plastic structures are typically addressed using time-history response analysis, which requires multiple repetitions and advanced computing. This alternative approach transforms ground motion into impulses and by takes an energy balance approach.
This is accessible to undergraduates because it is based on the energy balance law, and the concepts of kinetic and strain energies, and can be used by practitioners for building and structural design. This presentation starts with simple models which explain the essential features and extends in a step-by-step manner to more complicated models and phenomena.
