State of Integration: Investigation of Integration in the A/E/C Community

AbstractIntegrated buildings are one goal of the architectural/engineering/construction (A/E/C) community. Integration implies quality work and it is perceived to add value to a project; but, how is integration defined and how is it applied? This paper reflects on the current status of integration and assesses where the industry stands. To do this, integration was evaluated through publicly available documents of the major professional organizations that represent the field. The American Institute of Architects; ASCE; two ASCE institutes (Structural Engineering Institute and Architectural Engineering Institute); the American Society of Heating, Refrigerating and Air-Conditioning Engineers; and the Associated General Contractors of America were examined for their commitment to and implementation of integration and integrated design. This survey of the resources has found that integration is important to the industry on the whole, but that the effort to include integration into the A/E/C industry varies in ...

Ten Years of the Architectural Engineering Institute

The Architectural Engineering Institute AEI will be celebrating its 10-year anniversary at the 2008 National Conference in Denver from September 25 to September 27, 2008. During its 10year-long history, the AEI has grown to become the premier professional organization for engineers who specialize in designing and constructing the technical systems within buildings. The AEI promotes an integrated, multidisciplinary approach to the design, construction. and operation of buildings, whereby engineers of various disciplines can unite, interact, and share knowledge in an effort to advance the state of the building industry. The AEI was created through a merger between the National Society of Architectural Engineers and the Architectural Engineering Division of the American Society of Civil Engineers. The AEI has grown to more than 8,500 members with more than 3,800 student members. During its brief existence, the AEI has had numerous significant accomplishments in meeting the needs and expectations of its membership. A few of the recent accomplishments include the following: • Creation of the Architectural Engineering Exam;

Creating a Forum on the Contribution of Architectural Engineering Education to the Profession

Architectural engineers in practice receive their formal education from a wide variety of sources, including the academic institution they attended. An academic education program does not have to have ‘‘architectural engineering’’ ~AE! in the title in order to contribute to the profession or to train students to be productive in the industry. The membership of the AE profession is made up of individuals from a wide variety of experience, practice, and educational backgrounds, not just the faculty and graduates of the AE schools. With only 14 ABET-accredited AE schools ~several additional AE programs are in various stages of development!, it is clear that a large number of those practicing in the AE field are not graduates of educational departments with the words Architectural Engineering in their names. In the past, this journal has published large numbers of papers from authors who neither graduated from nor worked at one of the AE schools. Many technical and academic papers from various architecture and engineering programs concentrating in some aspect of building design, construction, and operation have also been published in the pages of the Journal of Architectural Engineering ~JAE!. Promoting an AE-based education is one part of the mission of the Architectural Engineering Institute ~AEI! of ASCE. This not only encompasses various forms of outreach and continuing education efforts, but also includes the role of supporting and coordinating the voice of the ABET AE programs. This activity within AEI is centered on the Academic Council, which is composed of the Chairs and Department Heads of the AE programs within the United States. As of the date of this writing, there are 14 ABETaccredited programs in the U.S., with several others established, offering classes, or in the planning and proposal stages. While this is still a small amount compared with, for instance, the total number of traditional civil engineering schools, it is significant to note that from the mid-1980s until fairly recently, the number of ABET AE schools held constant at 13. This recent increase in AE program development is also matched by an increased interest in building design and construction by the more traditional civil, mechanical, electrical, and related engineering programs in this country. As the industry expands and buildings become more complex, the need for graduates from all sources with specific expertise in AE-related disciplines will continue to grow. The AE-related academic programs should continue to take the lead in defining the

CJ90-39. The method of dynamic analysis of variable mass for vibration screen motion : By Wang Jizong (Hebei Coal Mining Architectural Engineering Institute, Hebei, China) et al. Chinese J. Mech. Engng26, No. 3 (June, 1990), pp. 58–64

In mineral processing industries vibrating screens operate under high structural loading and continuous vibrations. In this regard, this may result in high strain rates, which may often lead to structural failure or damage to the screen. In order to lessen the possibility of failure occurring, theories and techniques for analyzing machine structures are investigated and applied to perform a sensitivity study of a newly developed vibrating screen. Structural strength and stability of a vibrating screen is essential to insure that failure doesn’t occur during production. In this paper a finite element analysis (FEA) on a reconfigurable vibrating screen (RVS) is carried out to determine whether the structure will perform as desired under extreme working conditions at the different configurations of 305 mm × 610 mm, 305 mm × 1220 mm and 610 mm × 1220 mm. This process is aimed at eliminating unplanned shutdowns and minimizes maintenance cost of the equipment. Each component of a screen structure is analyzed separately, stress and displacement parameters are determined based on dynamic analysis. In addition, a modal analysis was carried out for the first three (3) modes at frequency f of 18.756 Hz, 32.676 Hz and 39.619 Hz respectively. The results from the analysis showed weak points on the side plates of screen structure. Further improvements were incorporated to effectively optimize the RVS structure after undergoing an industrial investigation of similar machines.
