Structural behaviour of stainless steel frames. Safety against accidental seismic actions
(English) Stainless steel is one of the most promising construction materials due to its long service life, low maintenance requirements, excellent mechanical properties and high residual value. Nevertheless, for an efficient ...
Estudio teórico y experimental sobre el comportamiento no lineal de estructuras continuas parcialmente pretensadas
(English) Performance-based design (PBD) is a philosophy for structural design that puts emphasis on the realistic estimation of the structural behaviour and its relationship with the objectives of the final user, or ...
Mechanical characterisation of masonry in existing structures by means of laboratory and in-situ experimental techniques
(English) Masonry structures are among the most abundant construction typologies in the world, having been commonly built until the second half of the 20th century. The determination of the mechanical properties of these ...
Methodology for seismic vulnerability assessment of existing masonry buildings in urban centres. Application to the Eixample district in Barcelona
(English) Unreinforced masonry buildings (URM), which prevail in many historic and urban centres, can be considered to be significantly vulnerable to seismic actions due to their peculiar constructive and structural features ...
Development of low-cost sensors for structural health monitoring applications
(English) There is increasing interest in developing low-cost sensors for economical structural health monitoring of civil engineering infrastructures. In addition to their price, they have the additional benefit of being ...
Building information modeling for facility managers
A Decision Support System (DSS) can help facility managers to improve building performance, occupants’ comfort, and energy efficiency during the Operation and Maintenance (O&M) phase. These DSSs are normally data-intensive ...
Vegetable Fiber Reinforced Calcium Aluminate Cement based composites for construction materials VFRCCs
Vegetable Fiber Reinforced Cement Composite Materials (VFRCC) have emerged as a potential construction material, providing adequate load-bearing capacity and ductility for non-structural applications. VFRCC have good ...
Sustainability, durability and mechanical characterization of a new recycled textile-reinforced strain-hardening cementitious composite for building applications
Cementitious materials have one of the highest compressive strength-to-weight ratios compared to other construction materials. Nonetheless, both tensile strength capacity and toughness result to be an order of magnitude ...
Refuerzo de estructuras de hormigón armado y pretensado por conversión a sección mixta mediante hidrodemolición
This thesis develops a new structural strengthening technique: converting existing reinforced concrete structures to composite sections by inserting connectors after controlled demolition with high-pressure water. The key ...
Fibre reinforced concrete column-supported flat slabs : from material and structural characterization to design and economic optimization
Fibre reinforced concrete (FRC) has proven to be a suitable material for statically indeterminate elements. The FRC column-supported flat slabs with partial or even total substitution of reinforcing steel bars constructed ...
Non-linear finite element analysis oriented to optimisation of fibre reinforced concrete structures
The construction industry is one of the industrial sectors with the largest output worldwide and, thus, of great economic interest. In this sector, reinforced concrete plays a significant role since it is one of the most ...
Models de priorització d'inversions utilitzant criteris de desenvolupament sostenible
This Doctoral Thesis addresses aspects of interest for hydraulic infrastructure managers, such as investment decision support tools, in order to provide both decision support and the justification tools which are required ...
Consideraciones relativas al diseño y a la alta durabilidad de dovelas de hormigón reforzado con fibras no metálicas (HRFnM)
The use of the fibre reinforced concrete (FRC) as a construction material has expanded beyond the traditional applications since the publication of design codes and structural guidelines. Fibre reinforced concrete for ...
Seismic design of steel beam-to-column joints with reduced beam section using European hotrolled
The design rules on Reduced Beam Sections (RBS) are covered in the Eurocodes in EN1998-3 as a possible solution to improve rotation capacity of beams for the retrofit of existing structures. The design rules are very similar ...
Study on the shear and punching-shear strength of reinforced concrete slabs subjected to point loads and in-plane tensile forces
Reinforced concrete members, especially when subjected to concentrated loads, can fail in shear. This is an undesirable and brittle failure mode preventing the structure from deforming and reaching higher load levels. It ...
A machine learning based material homogenization technique for masonry structures
Cutting-edge methods in the computational analysis of structures have been developed over the last decades. Such modern tools are helpful to assess the safety of existing buildings. Two main finite element (FE) modeling ...
Recomendaciones para el proyecto de puentes de ferrocarril con aparatos de apoyo de núcleo de plomo (LRB) en zonas sísmicas
Railway bridges located at seismic zones are particularly complex structures that present exceptional difficulties due to the existence of the track and the phenomena associated to it called track-bridge interaction. The ...
Structural behaviour of masonry arches on moving supports : from on-site observation to experimental and numerical analysis
Since ancient times, master builders have used arches to cover large spans in masonry structures. As a consequence, nowadays the safety assessment of these structural elements plays a fundamental role in the conservation ...
Performance of distributed optical fiber sensors embedded inside reinforced concrete structural elements.
The employment of a novel cutting edge strain monitoring technique named Distributed Optical Fiber Sensors (DOFS) as Structural Health Monitoring (SHM) tools is becoming increasingly common. Its popularity can be attributed ...
Structural system identification by dynamic observability technique
Structure system identification (SSI) can be classified as static and dynamic depending on the type of excitation. SSI by Observability Method (OM) using static tests was proposed and analyzed to address the observability ...
