A New Look at Structural Energy Dissipation.
Abstract
The investigation is the first step of a continuing study on energy dissipation in large, dynamically loaded structures. Work is directed at qualitatively and quantitatively defining the dissipative properties of complex structural systems, with a view toward improving the considerations of energy dissipation and nonlinear response in the seismic analysis and design of buildings. The present study deals with the extension of finite element methods to provide an analytical means for determining energy dissipation caused by cyclic plasticity in cyclically loaded structures. A computer-based cyclic stress-strain simulation model is developed which serves as the basis for the finite element constitutive relation. The model's behavior incorporates hysteretic material behavior and load history effects. It is experimentally verified for A-36 steel. (Modified author abstract)
