| Abstract |
This study was attempted to make a study of the bending behavior of T-section Modular Composite Profile Beams(TMPB), which is characterized by mass production, less construction period, and cost saving of the module, by modular assembly of the cross section through experiments and on the basis of the theory, and to look into the applicability of major parameters by changing thickness of the lower module mostly being under tension. As results of the experiments, T1-1 sample where thickness of the upper module and the lower module was same displayed fully combined plastic behavior of the modules, which indicates the good performance of TMPB by thin film profile. For T1-2 sample where a thickness ratio between the upper module and the lower module was 2, the rate between experimental value and theoretical value was 79%, thus it is deemed applicable. On the other hand, for T1-3 and T1-4 samples where a thickness ratio between the upper module and the lower module was large, the rate between experimental value and theoretical value was 50% or so, which indicates that it did not fully display plastic behavior. Putting initial stiffness, ductility and strength together, it is deemed that TMPB can be fully applicable as long as a thickness ratio of the upper and lower modules is 2 or less, and that further studies on shear reinforcing method are necessary. |
