Abstract
The design of tall building structures is both time consuming and labour intensive. Even with the availability of various engineering software, computer utilization in the present practice of design work is mostly carried out in a piecemeal manner and not coordinated with structural analysis, detailing and drafting. In engineering practice, an integrated system which can address the sharing of data communication will result in coordination among design activities. It will also improve design reliability and increase the productivity and efficiency in terms of time and cost. To obtain these benefits, two major issues must be addressed (a) approaches for information exchange and (b) controlling of information exchange in a truly integrated system. This study utilizes a centralized database method and a Level Manager based problem solving architecture to create a theoretical as well as practical system integration model for computer aided design of tall building structures. In this integration model, the central database, which consists of a component-subsystem model and a hierarchical index based object-oriented database management system, provides an efficient way to integrate the design information. In addition, five fundamental Level Managers are identified to model the structural design of tall buildings, and they in turn provide a design environment for various design activities and their software tools. A special Level Manager named Database Server Level Manager is introduced to connect the fundamental Level Managers to the central database, thereby realizing an efficient information exchange method and an intelligent way of coordinating design activities and their corresponding software tools. The high modularity of this system architecture makes it suitable for incremental development of a practical integrated system. A prototype system named TBCAD is developed to illustrate the implementation of the proposed integration model. The nature of TBCAD provides an open design platform for utilizing the existing design software tools in an efficient and intelligent way. Two examples are presented to demonstrate the system's functional capability in assisting of the structural design of tall buildings.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
