| Abstract: | A method for optimization design of cross-section of simply supported steel-concrete composite beams considering interface slip is introduced. Aiming to get the minimum value of manufacturing cost, a mathematical model is developed on condition that the calculation of deflection is based on stiffness degradation owing to interface slip. The complex method is adopted as the algorithm and the computer program is made with Matlab language. The validity and potential of the proposed approach has been demonstrated with a simply supported steel-concrete composite beam. |
