    Abstract
  • In new steel-concrete combinatory concealed-beam floor structure,the changes of the parameters of the steel concealed-beam are important factors,which impact the performance of the new combinatory concealed-beam floor structure.In order to investigate the effects on force bearing and deformation characteristics of the new combinatory structure,which caused by parameters such as the span,pitch,cross-section height and hole rate of web plate of steel concealed-beam.ANSYS is used to do the nonlinear analysis of the changes in the parameters.The result shows that the span of concealed-beam is significant to the bending stiffness and ultimate strength of the new combinatory concealed-beam floor;its influence is limited when the rate of opening in the web is within 26 percent.The pitch and cross-section height have less impact.The stress state of steel concealed-beam and concrete floor are changed with different span,pitch,cross-section height and hole rate of abdomen plate of steel concealed-beam.
