Bearing capacity calculation of U-section steel-encased concrete composite beam
摘要
Abstract
As a new type of composite beam,calculating the bearing capacity of U-section steelencased concrete composite beam is the premise and foundation for the application of the beam.According to the plastic theory and the superposition principle,the calculation method of ultimate bending capacity under positive and negative moment,vertical shearing capacity,longitudinal sheafing capacity as well as longitudinal sliding capacity for the beam were theoretically studied,and the calculation formula were established.The results calculated by the formula and the experimental data were compared to prove the applicability of the formula.The results show that the formula can be used to predict the ultimate bending capacity of the composite beam.The vertical shearing capacities for the beam are composed of two parts,one is that of the web for U-section steel,the other is that of the filled-concrete in U-section steel.The calculation methods of longitudinal shearing capacity as well as longitudinal sliding capacity is feasible,which can prevent the longitudinal shear failure and the longitudinal slip failure of the composite beam.关键词
