Optimization Design of Reinforced Concrete Frame Structure based on pseudo full internal force

In order to solve the optimization problem of reinforced concrete structure,Based on the design concept of full bearing capacity, a new reinforced concrete frame structure optimization design method--the full internal force design method is proposed. This method can solve the problem that the reinforced concrete frame structure has many constraints and is difficult to optimize in the design process. It can deal with multivariable and multi-constrained discrete variable structure optimization design problems with both size constraints, reinforcement constraints and bearing capacity constraints. The results of the example show that the method has strong local optimization ability, high optimization efficiency, simple application, and can directly calculate the optimization problem of reinforced concrete frame structure. It is a feasible and effective optimization design method.
