This paper proposes a cognitive approach for analyzing and reducing the Pareto optimal set for multi-objective optimization (MOO) of structural problems by means of jointly incorporating subjective and objective aspects. ...
The construction of bridges has been necessary for societies since ancient times, when the communication between and within towns, cities or communities was established. Until recently, the economic factor has been the ...
[EN] Structural optimization is normally carried out by means of conventional heuristic optimization due to the complexity of the structural problems. However, the conventional heuristic optimization still consumes a large ...
[EN] The construction sector is one of the most active sectors, with a high economic, environmental and social impact. For this reason, the sustainable design of structures and buildings is a trend that must be followed. ...
[EN] Nowadays, sustainability assessment tends to focus on the biophysical and economic aspects of the built environment. The social aspects are generally overestimated during an infrastructure evaluation. This study ...
[EN] In bridge design, many variables like material grades, cross-sectional dimensions, passive and prestressing steel need to be modeled to evaluate structural performance. Efficiency gains are intended while satisfying ...

[EN] The main objective of this work is to study the sustainable needs of Spain from the selection of criteria in the recruitment of public works, this work finally focuses the analysis in Spain to identify its sustainable ...
Manzano Alvarado, Mateo Xavier(Universitat Politècnica de València, 2020-01-27)
[EN] Delays and cost overruns in the construction works are a global phenomenon, their appearance is so
common that it has come to assert that they are an integral part of the projects. Despite of the numerous
efforts ...

[EN] This paper deals with the cost optimization of road bridges consisting of concrete slabs prepared in situ and two precast-prestressed U-shaped beams of self-compacting concrete. It shows the efficiency of four heuristic ...
This paper aims to find sustainable designs of post-tensioned concrete box-girder pedestrian bridges. A hybrid harmony search algorithm combining threshold optimization is used to find the geometry and the materials for ...
[EN] Lean philosophy introduces a new approach for maximizing value while minimizing waste, facilitating sustainable practices at the same time. Companies have become aware of these improvements and are demanding students ...
In this paper life cycle assessments are carried out on 30 optimized earth-retaining walls of various heights (4e13 m) and involving different permissible soil stresses (0.2, 0.3 and 0.4 MPa) in Spain. Firstly, the ...
Purpose Blended cements use waste products to replace
Portland cement, the main contributor to CO2 emissions in
concrete manufacture. Using blended cements reduces the
