Modelling of full and partially shear connected composite beam with finite element method

Steel material is commonly used in the most important economically improved countries for several years [1] . The academic research about steel has started to share a high market in our country . Developing composite behaviour on slab beams , which gains a save of money , is an important point . Followed researches show , adding the concrete strength to beam strength reduces the section of the slab beam and reduces costs . The only way to obtain real composite behaviour between those two materials is to use shear connectors between them . Most commonly used of those connectors are shear studs .In U.S. and european countries , there have made several researches about composite beams . There are several experimental studies done in early years . But, because of they are very old , it is hard to access to the data of those , and if only accessed , it is generally not reasonable to verify those data . To have an experimental study in labrotary about composite beams is very expensive and time consuming .In this research , it is tried to find as many experimental studies as and tried to be solved by finite element modeling techniques . Nowadays computer sciences made it easy and fast to work with 3D analysis programs . In this subject SAP2000 commercial program used , and the results tried to be compared by the experimental studies . The differences in using the shear studs providing the composite action , single or pairs have been observed . The different ways of modelling studs investigated.
