A method of structural optimization for upper beam is proposed in order to satisfy the requirements of high stiffness and light weight of isothermal hydraulic press. Finite element analysis mold is established in ABAQUS by analyzing structural features and load conditions of hydraulic press. When original structure is retained, stiffness and strength of upper beam are checked based on finite element analysis mold. Key factors influencing stiffness and mass are extracted and analysis results are obtained by experiment design. Mathematical model for structural optimization is established by second order stepwise regression model. The goal of structural optimization is to increase stiffness of upper beam while mass is set as constraint. The stiffness of upper beam is increased by 7.04% and its mass remains unchanged basically when structural optimization is finished.

The aim of the article is to present a developed algorithm of a stepped structural optimization method in the case of load combinations. The presentation of external loading via load combinations usually is employed in design codes. The pin‐jointed steel structures as light‐weight ones are widely used in actual engineering practice. The employment of dissipative features of material via elastic‐plastic model ensures a significant reduction of structural carrying capacity reserves (essential economic effect) versus the employment of structural response only in the elastic range. The stability, stiffness, constructional requirements and actual functions for cross‐sectional properties of standard profiles are employed in the optimization process aiming to obtain an optimal light‐weight structure which deformed behavior is compatible with codified requirements for such class of engineering structures. FEM mathematical models realizing structural optimization method steps are developed.
