Study and simplified calculation of transverse distribution coefficient of simply supported Ⅰ-shaped steel-concrete composite beams
Steel-concrete composite beams have the tensile properties of steel and the compressive properties of concrete.At the same time,the overall cost has significant advantages compared to steel beams,which has obvious application advantages in urban construction.However,the research on the transverse distribution coefficient and simplified calculation of steel-concrete composite beams based on engi-neering examples is scarce.Therefore,a bridge reconstruction project is selected in this paper,and the object is simply supported Ⅰ-shaped steel-concrete composite beam.The transverse distribution coefficient of the simply-supported Ⅰ-concrete composite beams is studied by analyzing the parameters of bridge width,interbeam spacing,interbeam strength and the number of main beams.Compared with the rigid beam method,the rigid plate beam method and the orthotropic plate beam method,the finite element calculation of the simple supported Ⅰ-shaped steel-concrete composite beam is simplified.
