Comparative review on integration levels between design and analysis systems /

Abstract

Building design is a broad and intensive collaborative process that involves a multitude of tasks and responsibilities that need to be accomplished in a timely and qualitative manner. The design process has a clearly expressed iterative nature - each solution is initially raised as a hypothesis, which is further discussed, analysed, calculated, checked, including compliance with normative requirements, and then final decisions are made after analysing several possible alternatives. This takes place in each team (discipline) of the project participants by comparing analysis results and anticipating the possible impact of decisions on the solutions and results of other design teams (disciplines). Therefore, it is very important to coordinate, synchronize, reconcile, and manage these decision making iterations in a collaborative environment. The Building Information Modelling (BIM) technology encourages the development of harmonized information production and management processes, creating preconditions for real collaboration between design partners in a unified model (the prototype of real building) environment and enables this model to be used for multivariate virtual testing. This feature is realized through the integration of modelling and analysis and computing systems, when the data transfer from one system to another system ensures the connection between the physical and the analysis model and the integrity of their data. The article deals with the integration levels and systemic directions of architectural and structural modelling and design computation programs. The problem of physical construction model creation and conversion into analysis model is defined and the stages of Computer-Aided Design/Competer-Aidet Engineering (CAD/CAE) integrated design process are discussed.
