Abstract: Evaluation on energy consumption is a key point for research of energy-saving work, and the current research mainly focuses on the energy consumption of individual processes. In order to solve the problem of energy consumption for the whole process of steel enterprise, three types of energy consumption indicators are proposed: comprehensive indicator, process energy consumption indicator and energy recovery indicator. A TOPSIS model has been established for energy consumption of steel enterprise. In order to avoid the tolerance caused by experts’ subjective consciousness, in the model, the indicator weight will be confirmed by entropy weight. Five steel enterprises were evaluated using this model. The result of evaluation is almost the same as the result of benchmarking analysis method, which has verified the availability of the model. The model has primarily solved the energy consumption problem for the whole process of steel enterprise.

Abstract: In order to study the comprehensive effect of material flow and energy flow on energy consumption of steel manufacturing process, firstly, the using energy peculiarity and energy saving technology of energy process of steel enterprise were analyzed. Secondly, the evaluation index of energy saving for steel enterprises was put forward based on analytic hierarchy process. The rule layer includes process energy consumption, steel ratio and application of energy saving technology. The variable layer includes 22 indexes. Indexes’ weight of rule layer, steel ratio and application of energy saving technology was determined by analytic hierarchy process and Delphi method. Indexes’ weight of process energy consumption was determined according to the average process energy consumption value of key steel enterprises in china. Finally, the evaluation index system of energy saving for steel enterprises was established. With the index system, the energy saving level of one steel enterprise can be evaluated according to its actual production data. The index system is practical and easy to apply.

Abstract: The document concerns with the design and study of a large masonry model of Hagia Irene in Istanbul. The goals of experimentation were to acquire a deeper structural behaviour knowledge than that possible to acquire with numerical models only and to assess the effectiveness of the consolidation works foreseen on Hagia Irene. The scale factor chosen is equal to 1:10. The tests were arranged into two different phases: for not reinforced and reinforced scale model .The displacements of the markers placed on the structure were registered by an innovative monitoring technique measuring 3D motion time histories.
