국내 건축물 설계 및 시공단계에서의 BIM 적용에 대한 건설 전반적 운영의 기대치인 설계 BIM의 재활용 및 시공단계에서 필요한 견적, 공정 등의 정보 추출 및 활용을 만족하기에는 연계되는 모바일 기술이나 단말기기의 현장 보급 및 적용이 부족한 상태이다. 따라서 본 연구에서는 이러한 BIM 세부 업무 프로세스에 대해 모바일 기술 적용의 4D 시뮬레이션 및 Test-Bed 신축건축물 대상으로 기획·계획·기본·실시설계 및 시공단계에서 3차원 3D와 공정관리 4D 시뮬레이션 및 5D 물량산출 BIM 모델과 라이브러리를 구축하고, 시공단계에서 BIM 모델을 통한 간섭체크 등 다양한 시공성 검토를 보다 효과적으로 활용하는 건설업무의 BIM 프로세스에 대한 표준화 수립을 제시하는데 목적이 있다.

본 연구는 설계초기단계에 적합한 VE 적용방안을 제안하고자 하였다. VE방법론은 설계단계 초기에 적용할 경우 더욱 효과적이므로 본 연구는 설계 프로세스 초기단계의 설계YE에 초점을 맞추고 있다. 관련 연구문헌의 고찰과 실무경험을 바탕으로 국내 건설산업에서 설계VE의 문제점을 도출하였다. 이러한 문제점을 해결하기 위하여 본 연구는 (1)설계단계별 VE실시시기를 구분하고, (2)건설산업에 적합한 VE대상선정 방법을 제안하며, (3)기능분석 프로세스를 보다 합리적이고 실용적으로 개선함으로써 (4)전체 설계VE 수행절차를 효율적으로 개선하고자 하였다.

For the improvement of APR1400 Diverse Protection System (DPS) design, the Advanced DPS (ADPS) has recently been developed to enhance the fault tolerance capability of the system. Major fault masking features of the ADPS compared with the APR1400 DPS are the changes to the channel configuration and reactor trip actuation equipment. To minimize the fault occurrences within the ADPS, and to mitigate the consequences of common-cause failures (CCF) within the safety I&C systems, several fault avoidance design features have been applied in the ADPS. The fault avoidance design features include the changes to the system software classification, communication methods, equipment platform, MMI equipment, etc. In addition, the fault detection, location, containment, and recovery processes have been incorporated in the ADPS design. Therefore, it is expected that the ADPS can provide an enhanced fault tolerance capability against the possible faults within the system and its input/output equipment, and the CCF of safety systems.

To design the shear connections for vertical construction joints of slurry walls, it is necessary to create a force-displacement curve that represents the structural performance of the shear connections. This paper proposes a method for preparing the force-displacement curve of the shear connections including major considerations.

A paradigm shift in teaching modular construction in higher education and K-12 is proposed as a means to increase the future adoption of the modular construction technique. To this effect, a new education module is presented to STEM educators. This education module is based on LEGOs and directed towards educators in the architecture, engineering, and construction (AEC) industry. The main objectives of the education module are to increase interest and knowledge of modular construction, acknowledge the benefits of using 3D design with 4D scheduling, and create a simulating hands-on educational opportunity. The education module is designed to allow participants to experience a hands-on simulation of modular construction and stick-built construction through building a LEGO project. Participants are challenged to find the advantages and disadvantages in both construction systems first-hand and record their findings. Results are presented from the preliminary testing of this education model on a group of construction management students at the University of Nevada, Las Vegas. Overall, the survey results showed that the LEGO education module was successful at achieving the project's three main objectives: 1) increasing the participants' interest and knowledge of modular construction through an interactive project; 2) increasing the participants' understanding of the benefits of 3D design with 4D scheduling over the use of 2D drawings; and 3) creating a simulating hands-on educational opportunity to help participants compare modular construction to stick-built construction. In the end, this proposed a new LEGO education module addressing the problems identified from this study with more participants.

This paper describes recent developments in composite construction and their effect on codified design procedures in the UK. Areas of particular interest include: rules on shear connection, design of beams with web openings, serviceability limits, such as floor vibrations, and fire safe design. The design of cellular beams with regular circular openings now includes generalized rules for web-post buckling, and for the development of in-plane moment in the web-post for asymmetric sections. Closed solutions for the maximum shear force due to limits on web-post bending or buckling are presented. The fire resistance of cellular beams is also dependent on the temperature of the web-post, and for closely spaced openings. It is necessary to increase the thickness of fire protection to the web. For serviceability design of beams, deflection limits and natural frequency and response factor for vibration are presented. It may be necessary to use stricter limits for certain applications.

With the booming of construction and property industries in China, the demand for high-rises and mega-scale buildings with more integrated building functions, open- and tailor-shaped outlooks, better connections to municipal infrastructures, and higher grades of building importance has been increasing in the past two decades. The seismic design and engineering of such modern mega-buildings face engineering challenges such as hazard mitigation of extreme actions and surroundings, integrated structural frameworks and building skins, complex connections, and overall construction efficiency. It is the work of a new generation of civil and structural engineers to enhance engineering efficiency and achieve overall engineering, environmental, and economical effectiveness for these high-rise projects. This paper elaborates the above topics through case studies on the design and construction of four such developments in China. Some rethinking is conducted on evolution in modern seismic engineering and design through innovation to achieve an acceptable level of overall sustainability and building effectiveness.
