In the present paper, innovative joint configurations leading to more economical solutions for full-strength beam-to-column joints for seismic building frames are detailed. The specificities of these joints are due to the fact that (i) the column is made of high strength steel while the beam are made of mild carbon steel and (ii) the design of some components allows partially neglecting the overstrength factor. Also, methods for the characterisation of specific joint components not directly covered by the Eurocode recommendations are proposed. [less ▲]

Behaviour of bolted flange joints in tubular structures under monotonic, repeated and fatigue loadings I: Experimental tests

This paper presents a test program on bolted flange plate connections used in circular tubular structures. In the tested joints, the connected tubular elements are made of high strength steel (TS590) whilst normal steel grade (S355) is used for the flanges. The tests were performed under monotonic loadings to obtain the mechanical properties of the connections and under cyclic loadings to characterise the behaviour of these connections for low cycle and high cycle fatigue. The test results are first presented herein, including a critical analysis of the latter; then, designmethods available in literature are applied for the tested configurations with the objective to investigate the accuracy of these methods through comparisons with the experimental results.

Gap analysis on robustness of tubular structures

Recent events such as natural catastrophes (tsunami, hurricane, …) or terrorism attacks have highlighted the necessity of ensuring the structural integrity of buildings under exceptional events with the objective to save the life of the occupants and of the safety services (fireman, ambulance man, …) and also to avoid collateral damages to the adjoining buildings. The partial collapse of the Ronan Point Tower in 1968 in UK is considered as the starting point of the interest in the structural integrity of buildings but more recent catastrophes in the last decade such as the terrorist attack of the World Trade Center towers in 2001 or the earthquake/tsunami in Fukushima in 2011 have increased the interest of the engineering community and also of the population in this topic. According to different national and international design codes, the structural integrity of civil engineering structures should be ensured through appropriate measures but, in most of the cases, no precise practical guidelines on how to achieve this goal are provided. In the present report, some definitions are first given. Existing codes and standards are then reviewed and main conclusions are drawn on their adequacy to the present needs of practitioners. From this analysis, general and specific research needs within CIDECT are identified. These ones are detailed in two dedicated sections respectively on buildings and trusses. A summary table draws the main conclusions in terms of future required CIDECT investments. Finally some references to literature are listed. [less ▲]
