| Abstract |
The object of this paper is to evaluate on behavior the experimentally of beam in a welded connections for unit modular steel frame with the hollow structural steel section to light steel section. The connections carried out test on the connection shapes bracket-type and diaphragm-type to consideration which the connections for unit modular steel frame was capacity, deformation and failure mode. Test of results, the connections strength decided to beam of the lateral buckling strength in light steel section regardless of connection shapes and connection failure. The strength & stiffness for connection increase proportionally as the light steel section beam section sizes, and the more bracket-type than diaphragm-type as connection shapes. The results from theory of lateral buckling are compared to the experimental results. The ratio of experimental results to theory value is 0.84～1.00 in the case of bracket-type and diaphragm-type of 0.83, indicating an accurate and safe estimation. |
