On the Nonlinear Transient Analysis of Structures

“…Another important conclusion is that the mathematical model of the concrete has a significant influence on the nonlinear transient response of structure (earthquake analysis) and reality is somewhere between analyzed elasto-plastic and elasto-damage behavior and thus we recommend using combination of plasticity and damage models simultaneously. The Friction diagram [1].…”

“…The numerical process of direct integration of the equation of motion (1) in a time interval t ∈ t 0 , t m hi is called transient analysis. Time is discretized to finite number of time instants t 0 ,t 1 , … ,t m .…”

“…But to take advantage of these developments, the use of spectral analysis must be abandoned and a method of direct integration of the equation of motion must be used (also called the transient or time history analysis). Several aspects of this area, including the comparison of the explicit and implicit method in seismic analysis [1,2], suitable material models, and sources of dynamic damping are discussed in this chapter. Subchapter 2 deal with several aspects of the transient dynamic approach in seismic analysis.…”
