Development of Optimization Design Programs for Composite Beams

합성보의 최적설계 프로그램 개발

The object of this study is to develop computer programs with which ordinary engineers can analyse or design steel-concrete composite teams using optimization technique. Various design ana construction techniques which could maximize load carrying capacities and control concrete tension cracks effectively are studied and included in the programs. Analysis results show that proposed construction techniques can reduce steel weight by about 10%∼20% compared with ordinary composite beam. Concrete tensile stresses can also be controlled affectively by the suggested techniques.
