Abstract:
In reinforced concrete frames that underwent different loading paths, moment development was accurately predicted with a nonlinear analytical method. The nonlinear behavior of reinforced concrete frames with sidesway is governed by two factors: the nonlinearity of materials due to cracking and plastic behavior, and the nonlinearity of geometry caused by second-order deformation. These two factors may interact and yield a combined effort known as the nonlinearity of geometry and materials. Related questions arising from American and European codes of practice were examined through experiments and analyses.
