| Abstract: | A model of the finite element analysis considering the slip effect of stud and the function of steel bar is established in order to research the mechanical properties of steel-concrete composite beams under static load.It is conducted a comparison between composite steel-concrete beams with open section and those with box section about flexural performance,development trend and distribution characteristic of cracks.The curves of strain and stress of concrete and those of steel beams are anastomotic with the... |
