Abstract:
A new step-by-step method for the analysis of earthquake stresses in multi-story frame buildings is presented and compared with the rigorous solution of the same problem to evaluate its efficiency. The following essential factors influencing earthquake stresses are considered: (1) stiffness and internal damping of the resisting structure; (2) rocking of the foundation due to the yield of the ground and (3) period and amplitude of the earthquake componets. It is hown how the method can be extended to buildings in which stresses beyond the elastic limit create plastic hinges. Estimates of time and labor required by the proposed method are presented.
