Use of Multi-Criteria Optimization for Selection of Building Materials for Reconstruction

Abstract

Problematic of optimizing the selection of a suitable building material for reconstruction in the Czech Republic is a frequent topic. The paper reviews the methodology of multi-criteria evaluation of partition walls for the following criteria: the mechanical-physical, technological, economic, but also ecological. The multi-criteria evaluation methodology can be used at an early stage of construction, in the decision process of selecting the most suitable material variants for designing interior non load-bearing walls.

Application of Multi-Criteria Optimization for Selection of Building Materials for New Buildings

“…For mathematical modeling in a multi-criteria optimization method we have to select and specify the list of evaluation criteria and we determine the set of real material´s variant to prepare the decision-making criterion matrix. In this matrix, the columns correspond to the criteria (7 evaluation criteria) and line material´s variants (variant 8 tracks partitions), see equation (1).…”

“…The choice of materials and technologies for the quality of the works decisive step which can be used at an early stage of construction preparation [1,3]. An objective method of multi-criteria optimization of the selection of materials for partitions (as from glass [2]), which eliminates or minimizes subjective view of participants in the construction process is of great benefit.…”

Reconstruction of the Municipal Bath House

“…In places where the steel was missing or peeling off in big scales from the reinforcing rods, the original steel was removed and replaced with new one. The reinforcement was improved by new rods which were welded to the exposed end of the existing rods [9]. The redevelopment was made using the steel with well-proven weldability and same strength as was that of the existing structure.…”

“…More and more attention has been paid to improvements of the reinforced concrete structures because more and more structures have becoming degraded both in the Czech Republic [2], [3], [5], [9], [10] and abroad, see, for instance, [1], [4]. Various issues should be addressed when assessing, diagnosing and designing technologies and materials for redevelopment, see [6], [8].…”

The Verification of Range of Chemical Grouting of Wet Masonry by Theoretical Modeling and by Using Infrared Camera

“…The contribution presents the results [2] of pilot measurement and the proceeding of the initial intention of using mathematical modeling or other methods of evaluation [3] for the supposed range of grouting masonry to verify the range by the infrared radiometric long-wave system. The measuring took place within the Moravian-Silesian region: Support of Science and Research in the Moravian-Silesian Region [2] and some results have been published in several articles f.e.…”
