  • Recently, many studies have conducted to satisfy a physical need of human between environment of light on space, so an atrium structure has been applied to cultural complex. However, this structure brings about many problems such as overheating in summer, excessive vertical temperature differences, condensation, diffusion of noise, effect of echo, and withering landscapes. Especially, in this research, thermal comfort by difference of vertical temperature in the space of atrium and the optical characteristics of glass skins of the atrium could be remarkably effected by solar flux entering indoors.

  • Traditionally, the construction industry has shown low labor productivity and productivity growth. To improve labor productivity, it must first be accurately measured. The existing method uses work-sampling techniques through observation of workers' activities at certain time intervals on site. However, a disadvantage of this method is that the results may differ depending on the observer's judgment and may be inaccurate in the case of a large number of missed scenarios. Therefore, this study proposes a model to automate labor productivity measurement by monitoring workers' actions using a deep learning-based pose estimation method. The results are expected to contribute to productivity improvement on construction sites.

A Study on the Change and Characteristics of Stereotyped Japanese Elementary School in Meiji Era - Focusing on the Standard Drawings by Japanese Ministry of Education - (명치기(明治期) 일본(日本) 소학교건축(小學校建築)의 표준화 과정 및 특성에 관한 연구 - 문부성 제정 표준도 분석을 중심으로 -)

  • This study aims to examine Japanese elementary school architecture in Meiji Era, in which Japanese modern education system was settled down and the school architecture flourished by mass construction of stereotyped school buildings. It is assumed that stereotyped school architecture is due to the influence of the standard drawings made by Japanese Ministry of Education, therefore standard drawings could be a key to understand the characteristics of the stereotyped school buildings in Meiji Era. In this perspective this study attempts to analyze 4 standard drawings and interpret it in relation to regulations and design guidelines for school architecture in that time. As results of this study the change and characteristics of stereotyped school architecture in Meiji Era are clarified in several categories. They are as follows : the deviation of classroom and corridor, the change of classroom size fixing to 4 kan(間) by 5 kan(間), the absolute use of north-lacing single corridor type block-plan, and the change of other space such as waiting room(控所), special instruction room, auditorium and gymnasium.

  • The bolted end-plate beam-column connections have been widely used in steel structure and composite structure because of its excellent seismic performance. In this paper, the end-plate bolted connection is applied in the concrete structure, A new-type of fabricated beam-column connections with end-plates is presented, and steel plate hoop is used to replace stirrups in the node core area. To study the seismic behavior of the joint, seven specimens are tested by pseudo-static test. The experimental results show that the new type of assembly node has good ductility and energy dissipation capacity. Besides, under the restraint effect of the high-strength stirrup, the width of the web crack is effectively controlled. In addition, based on the analysis of the factors affecting the shear capacity of the node core area, the formula of shear capacity of the core area of the node is proposed, and the theoretical values of the formula are consistent with the experimental value.

  • The domestic and foreign scholars conducted many studies on mechanical properties of wave web steel beam and high-strength spiral stirrups confined concrete columns. Based on the previous research work, studies were conducted on the anti-seismic property of the end plate bolt connected wave web steel beam and high-strength spiral stirrups confined concrete column nodes applied with pre-tightening force. Four full-size node test models in two groups were designed for low-cycle repeated loading quasi-static test. Through observation of the stress, distortion, failure process and failure mode of node models, analysis was made on its load-carrying capacity, deformation performance and energy dissipation capacity, and the reliability of the new node was verified. The results showed that: under action of the beam-end stiffener, the plastic hinges on the end of wave web steel beam are displaced outward and played its role of energy dissipation capacity. The study results provided reliable theoretical basis for the engineering application of the new types of nodes.
