강성 기준에 근거한 Hexagrid 구조의 부재 선정에 관한 연구

Abstract

This study investigated structural performance of horizontal hexagrid(HH) and vertical hexagrid(VH) structural system based on the maximum lateral displacement, steel amount of perimeter structure, and combined strength ratio of exterior columns. The required moment of inertia of members are derived from relationships between force and deformation. Member size between modules is changed through the height of building, which was not considered in the previous studies. Based on the result of analyzed buildings conclusion of this study is as follows: (1) Vertical hexagrid structure was more efficient than horizontal hexagrid structure in lateral stiffness, (2) Exterior columns of vertical hexagrid structure resisted 90∼95% of lateral load on the other hand those of horizontal hexagrid structure took 60∼80% of lateral load. However, two systems showed somewhat similar result for gravity load distribution in exterior columns, (3) Proposed member selection met lateral displacement limit in most cases.
