접합부 유한요소해석을 바탕으로 한 모듈러 구조물의 힌지접합부 수치해석적 연구

Abstract

This paper introduces research on the hinge joint of modular structure joints using finite element analysis. The modular structure has acharacteristic in that it is difficult to expect the integrity of columns and beams between unit modules because the construction is carried outsuch that the modules are stacked. However, the current modular design ignores these structural characteristics, considers the momenttransmission for the lateral force, and analyzes it in the same manner as the existing steel structure. Moreover, to fasten the moment bonding,bolts are fastened outside and inside the module, resulting in an unreasonable situation in which the finish is added after assembly. To considerthe characteristics that are difficult to expect, such as unity, a modular structure system using hinge joints was proposed. This paper proposedand reviewed the basic theory of joints by devising a modified scissors model that is modified from the scissors model used in other research toverify the transmission of load when changing from the existing moment junction to a hinge junction. Based on the basics, the results wereverified by comparing them with Midas Gen, a structural analysis program. Additionally, the member strength and usability were reviewed bychanging the modular structure designed as a moment joint to a hinge joint.
