| Abstract |
The object of this paper is to evaluate on lateral resistance performance of lateral cyclic test for unit modular steel frame with the cold-formed the hollow structural steel sections column and light weight ㄷ-sections steel beam. Major variables include bracket-type and C-type is shaped joint. Lateral resistance in order to evaluate the performance of the unit frame having first and second floors by making full scale framing experiments were carried out. This study will be evaluated about stiffness and strength variations by form of joints, deformation shapes and failure modes through the test. Comparisons on the test of results in the story drift elastic limited ratio(0.01rad), the unit frame with joints bracket-shape showed highly lateral yielding load to 3～12%, peak load to 30～35% and lateral stiffness to 7～12%. The stiffness and strength of 2nd story unit frame were estimated some low at the same position. For the security of lateral structure safety regardless of joints shape and scale with the unit frame modular system that was determined to a fixed connector additional in light weight ㄷ-shape beams of between column-to-column with long-direction. |
