Abstract:
Computer simulation of the real behavior and response of a concrete structure when subjected to a load is the numerical technique of creating and executing of an idealized model; follow by analyzing the results. During the executing phase, a set of input parameters such as the geometrical data, properties of materials, boundary constraints and loads will be processed numerically to obtain a set of useful output such as the ultimate load-displacement curve and the anticipated cracked pattern. Subsequently, this output will be incorporated into a design process with the key objective of developing a reliable, safe and economical structure. In other words, an efficient manipulating of a numerical model using a digital computer will enhance the reliability of a design process and the creativity of design engineers in an attempt to achieve an optimized structure. Although it is used by the research department of the universities, its potential application as a practical design tool to perform a non-linear quantitative assessment has not fully realized yet. This is partially due to the lack of such advanced tool in executing a non-linear structural analysis and design of concrete structures. The second author is involved in the development of such tool, which is aimed to close up this gap. In this paper, the authors have introduced and demonstrated that the complex state of stress in concrete structures can be readily simulated using an advanced computer-aided tool.
