| Abstract: | Methods for analysis of composite?steel beams with profiled sheet are proposed in the paper.The beam is connected with stud shear connectors.Elastic stiffness and flexural capacity of the beam are less than that with traditional connection due to the slip effect.The reduced stiffness method is developed by the authors in a previous study,it is modified and extended to analyze the stiffness of the beam.Another analytical method is also proposed to calculate the flexural capacity of the beam with consideration of the slip effect.The results are in good agreement with that of the experimental results. |
