These studies experimentally investigates structural behavior and reinforcing effects by strengthening the Carbon Fiber Bar overhanging length ratio of hip rafter in hipped-and-gabled roof house as follows. 1) As a result of hip rafter member test, it is found that reinforced specimen shows increased yield load by 4.1%～45.8%, and ultimate load than non-reinforced standard specimen depending on the ratio of overhanging length by 0.6%～47.7%. Also, in yield load, based on the ratio of overhanging length increases, load shows decrease of 6.7%～32.2% in standard specimen and of 5.1%～19.7% in reinforced specimen. 2) As a result of comparing standard specimen to reinforced specimen according to the ratio of overhanging length of hip rafter, Ductile Coefficient shows increase in reinforced specimen of Ⅰ-Type (1:1.0) by 17%～26%, but Ductile Coefficient of standard specimen and reinforced specimen in Ⅱ-Type (1:1.2) and Ⅲ-Type (1:1.4) were similar. As a result of experiments and analysis with hip rafter member in traditional wooden structure, proposed retrofitting method with encased Carbon Fiber Bar is more rational than existing reinforcement methods such as slide installation, steel band reinforcement, plastering mud on the ceiling and core load adjustment and putting stone in the inside considering archetype preservation, structural safety and durability of cultural properties. |
