ABSTRACT

In this research, a test-bed large-span Hanok which adopts new structural system compared to the traditional structural system has been introduced, and the structural analysis and seismic design for it have been performed to test possibility as a large-span Hanok. The test-bed Hanok is composed of two parts, that is, 1st story part and 2nd story part. The roof structure of 1st story part is similar to that of the traditional Hanok, but that of 2nd story part is new-styled and different from the traditional Hanok. The two parts are joined together side by side. The largest span of this test-bed Hanok is 14.4m in 1st story part and 10.8m in 2nd story part. The structural design was done to extract optimal member size for both raw wood and glued laminated wood with satisfying safety and serviceability conditions. The comparison of the sectional area between raw wood and glulam showed that glulam required less member size than raw wood. The area ratio of the glulam compared to the raw wood is from 0.60 to 0.92, and this shows that, glulam is more economical than raw wood in large-span Hanok from the viewpoint of the required volume of the timber which affects much in cost and construction. Conceptual seismic design methods for the test-bed large-span Hanok were proposed and the structural characteristics of each method were discussed. The proposed method is summarized as addition of shear wall, reinforcing existing shear wall and isolating the basement of the structure from the ground.
