This paper presents a summary of the procedures for elaborating Eurocodes that started in last two decades 20th century with some emphasis Eurocode 2 on concrete structures. Besides, general scope technical content new proposal is commented and main changes are highlighted.

This article highlights the most relevant aspects of new generation Eurocodes for assessment existing structures, and in particular those governing concrete structures. In this respect, Eurocode 0 will include a section (prEN 1990-2. Basis retrofitting structures: general rules actions) covering approach analysis that must be included type assessment, while 2 (prEN1992-1-1:2021 Design structure...

It is generally recognized that heavy timber in fire conditions demonstrates high structural performance. Exposed timber chars which functions as an isolative layer which protects the inner material from heat and loss of load bearing capacity. Char has no significant strength, and therefore, as the char layer grows, the load bearing capacity of the timber member reduces under sustained fire con...

This paper describes four standard scale fire tests conducted on precast prestressed hollow core slabs under flexure. The influence of the reinforcement arrangement was investigated using two test parameters: the average axis distance (from 30.1 to 46.7 mm), and the type of reinforcement (5 mm diameter wires and 9.5mm diameter strands). An ISO 834 standard fire was applied maintaining the load ...

This paper presents the shear performance of reinforced concrete (RC) beams with Tsection. Different configurations of externally bonded carbon fiber reinforced polymer (CFRP) sheets were used to strengthen the specimens in shear. The experimental program consisted of six full-scale, simply supported beams. One beam was used as a bench mark and five beams were strengthened using different confi...

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 filled tubular columns with elliptical cross-section, the main objective of this paper is to compare the behaviour of such innovative cross-sections under ambient and high te...

This paper investigates whether the model uncertainty of reinforced recycled aggregate concrete (RAC) beams subjected to bending differs from that of reinforced natural aggregate concrete (NAC) beams. An introductory remark concerning the importance of the codification of RAC structural design is made and notions concerning model uncertainties and their role on structural codification are given...

Since 1990 he has been working at ICOM and is currently preparing a ...

The seismic performance of RC columns could be significantly improved by continuous spiral reinforcement as a result of its adequate ductility and energy dissipation capacity. Due to post-earthquake brittle failure observations in beam-column connections, the seismic behaviour of such connections could greatly be improved by simultaneous application of this method in both beams and columns. In ...
