The design of the corner joints in furniture structures is very important to firmly support the loaded structure and to sufficiently maintain the durability and stability. Therefore, the strength of the corner joints and the rigidity of the connected panels play a very important role in the structural performance of the assembled furniture. The structural properties can be measured or calculated experimentally or numerically, and compared by representing the applyed forces or bending moments as a function of deformed value. This paper shows the numerical models to determine the strength and stiffness of the 3-types of corner joints for simple designed furniture. Based on the finite element results, the maximum stresses are concentrated on the corner joints designed with MDF panels. And the deformation resistances and maximum applied loads are calculated for furniture corner joints under tensile and compressive moment.

개발된 완전 조립식 교량 하부구조에 대한 설계비교와 비선형 해석을 수행하였다. 조립식 교량 하부구조는 현행설계법과 하중저항계수설계법으로 설계하였다. 설계시에는 현 도로교설계기준에 규정된 DB-24 및 DL-24 설계활하중을 적용하였다. 이 연구는 비선형 유한요소해석을 통해서 완전 조립식 교량 하부구조의 현행 설계법인 KHBD (2005)와 AASHTO-LRFD (2007)를 평가하였다. 사용된 프로그램은 철근콘크리트 구조물의 해석을 위한 RCAHEST이다.

Traditional marine structures are difficult to construct under the marine environment. These structure have maintenance costs associated with the chloride attack environments. In this paper, a new structure system is proposed to overcome these disadvantages. The connection of precast reinforced concrete girders and bent cap is the main feature of the proposed structure system. To assess the joint performance of the proposed methods, full-scale joint was fabricated and tested under cyclic loading. The key parameters examined were the pile displacement; the strain in the reinforcement; and the crack patterns in the concrete. The test structure behaved stably for cyclic loading. The test structure is analyzed to be safe in all members.
