Solver User's Guide Version 2.2. Dynamic Response Analysis of Single Degree of Freedom Systems
Abstract
The objective of this study is to present the theory and the application of the Newmark-beta method for solving single degree of freedom (SDOF) dynamic problems. The SOLVER program applies the Newmark-beta method for solving SDOF systems. The SDOF system can be described in terms of a nonlinear stiffness with separate descriptions for the initial response and rebound. Mass and viscous damping can be included as constants or given a nonlinear description. The loading can be arbitrary and include multiple peaks and negative phases. In civil engineering studies, many problems can be reduced to simplified analyses. Specifically, the dynamic behavior of individual members and certain combinations of these members can be treated as SDOF systems. SDOF systems are a quick and economical way to evaluate a dynamic system and, therefore, are useful for parametric studies. In these problems, the response of interest is primarily the fundamental mode and can be described in terms of some gross behavior (e.g., centerline deflection). Further assumptions include simplified loadings and linear elastic structural response. The SOLVER program calculates the dynamic response of a user prescribed SDOF system and loading.
