This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete ...

The use of steel fiber reinforced concrete (SFRC hereafter) is becoming more and more common. Building codes and recommendations are gradually including the positive effect of fibers on mechanical proper ...

In this investigation, the characteristics and the rheological properties of two different nanocomposite systems were investigated. These systems consisted of a dispersion of carbon nanotubes (CNTs) and carbon nanofibers ...

The bond behaviour of prestressing strands in precast pretensioned concrete members, and its transmission length, depends on several factors. However, no consensus exists on the main parameters to be considered in the ...

[EN] The purpose of this Final Degree Project is to study the reinforcement of the CV-50 road between P.K. 6+425 and P.K. 11+000. Among the main objectives are to stop pavement degradation, increase the bearing capacity ...

[EN] This work consists of the analysis and later capture of decision of action, on a series of existing pathologies of the props of the floor of basement of a building

A method for calculating the design axial buckling load in the fire situation of unreinforced axially loaded concrete filled circular hollow section columns was presented by the authors in a previous paper [1]. In the ...

[EN] This paper describes standard scale fire tests conducted on four precast prestressed hollow core slabs configurations under flexure. The influence of the reinforcement arrangement was investigated using two test ...

En las estructuras actuales la investigación es un procedimiento (medio) para alcanzar un objetivo (fin) que permite el desarrollo de nuevas tipologías y materiales. En las históricas existe una bifurcación: los problemas ...

Modern self-tapping and continuously-threaded woodscrews enable new methods for strengthening and joining timber and glulam construction elements. As these screws have a high axial strength and an excellent continuous ...
