Hybrid computation programming techniques are used to study the dynamic behavior of certain inelastic systems and its dynamic responses due to earthquake excitations. The methods of solution are examined in detail. Sources of error and cost comparison with digital computation results are presented. Computed results confirms the conclusions obtained from theoretical predication. It has been found that P-Δ effect parameters have significant influence on the dynamic behavior of inelastic systems. These parameters, which are in dimensionless forms, are related to the masses, the lateral stiffnesses, and the height of each story of the structure.
