Research on the performance of recycled concrete as building material in the current world is an important subject. Given the complex composition of recycled concrete, conventional methods for forecasting slump scarcely obtain satisfactory results. Based on theory of nonlinear prediction method, we propose a recycled concrete slump prediction model based on geometric semantic genetic programmin...

Problem solving in IT consists of expressing an algorithm for abstract models of computation. This has proven to be hard, but it can be taught, specially when students are exposed to concrete and visual illustrations of artefact behaviour. IT graduates require problem-solving skills, but it is difficult to teach such problem-solving skills in the context of huge bodies of technological concepts...

Green concrete is a concept of thinking environment into concrete considering every aspect from raw materials manufacture over mixture design to structural design, construction and service life. Green concrete is a type of concrete which resembles the conventional concrete but the production or usage of such concrete requires minimum amount of energy and causes least harm to the environment. Si...

The paper reports the results of a joint project on evolutionary design of reinforced concrete structures in tall buildings. It has been conducted at the Center for Concrete Structures at the Darmstadt University of Technology in Germany and in the School of Information Technology and Engineering at George Mason University. Its ultimate objective is to revolutionize design of both steel and con...

Crack formation is common among concrete used for all different types of construction. While cracking is inevitable in concrete, it can create instabilities that can compromise an entire building’s structural integrity. New advancements are being made in the biological and engineering fields that are providing a solution to this problem. Certain bacteria and chemicals when mixed provide a react...

The Adaptively Shifted Integration (ASI) technique, which produces the highest computational efficiency in the finite element analyses of framed structures including static and dynamic collapse problems, is applied to the seismic damage analysis of a reinforced concrete building. By expressing member fracture by a plastic hinge located at the exact position with a simultaneous release of result...

Reuse of agricultural wastes and industrial by-products for building materials has been gaining popularity in the recent years. Agricultural waste material; namely rice husk ash (RHA), and industrial by-product; namely expanded polystyrene beads (EPS) are discarded in large amounts globally, causing increased environmental problems. Therefore, this paper introduces innovative efforts of the com...
