NONLINEAR ANALYSIS OF SEISMIC BEHAVIOR OF STICKY-STEEL REINFORCEMENT BEAM IN CYCLIC LOADING

摘要

This paper analyses the seismic behavior of sticky -steel reinforcement beam adopting nonlinear finite element. The concrete applies the incremental orthogonal abnormality analysis model based on the equivalent single-shaft strain and the constitutive relation of repetitive loading that takes fracture plane effect into account. The constitutive relation of steel takes Baushinger effect in cyclic loading into account. The result of calculation and test meet fairly.
