文摘

Nonlinear inelastic responses of steel frames with various base restraints are studied. Second-order effects are considered by stability functions, save computational time. Geometric, material and column-base restraint nonlinearities are taken into account. A solution procedure for nonlinear differential equations of motion is developed. Damping ability of nonlinear semi-rigid base restraints is illustrated.
