The fatigue behaviour of the welded beam-to-column connections of steel moment resisting frame in seismic area must be evaluated. The cohesive zone model is an efficient solution to study such connections by finite elements. It respects the energetic conservation and avoids numerical issues. A three-dimensional cohesive zone model element has been implemented in the home made finite element code Lagamine [1]. It is coupled with the fatigue continuum damage model of Lemaître and Chaboche [2]. The cohesive parameters are identified by the inverse method applied on a three points bending test modelling.

A quantitative comparison of two 15 storey high framesdesigned to resist a 0.4g PGAhas been made: one frame corresponds to a standard design in which connections of diagonals are capacity designed to the diagonal sections and the other one uses dissipative connections at the diagonals ends. The structures are designed by a standard elastic procedure under reduced forces. Pushover analysis and non linear dynamic analyses are then performed to assess the real behavior and performance of the structures. The advantages of using dissipative connections are confirmed in a high rise flexible building. [less ▲]

This contribution presents the results of an experimental investigation carried out on the shaking table of the National Laboratory of Civil Engineering of Lisbon (LNEC), in order to validate the efficiency of some constructive proposals aiming at improving the structural behaviour of non engineered masonry housing subjected to low to moderate seismic action, with rather low costs compared to traditional North-European practice. Two specimens have been tested. These specimens were two full-scale small houses with two levels. The first one was built as a traditional Belgian house, while the second included some anti-seismic technical details. The main conclusions are that both specimens were still standing at the maximum earthquake level foreseen for Belgium, but that the improved model was much less damaged regarding crack openings in the walls. Therefore the economic consequences and repair costs would be much lower with these improvements. However the maximum ground acceleration that can be sustained by the structures seems to be very little influenced by the constructional detailing. [less ▲]

This paper presents a non linear finite element numerical modelling of reinforced concrete and fully encased composite columns. The model is a multi fibres beam with mono-axial non linear material laws for concrete, steel and reinforcing steel. The crushing of concrete in compression and the cracking in tension are taken into account. The steel behaviour is elastic-plastic with strain hardening. After calibration against the experimental results, a parametric study is performed. The main objective is to obtain the full moment-rotation behaviour of the columns under different level of axial forces and with different resistance of concrete, and to deduce ductility and rotation capacity of the composite sections.

The paper presents a quantitative comparison of two seismic design of a concentric braced frame of 15 storey height for a 0.4 g PGA: one classical design in which connections of diagonals are capacity designed to the diagonal sections and one innovative design introducing dissipative connections at the ends of the diagonals. The structures are first designed by equivalent static design. Pushover analysis and non linear dynamic analyses are then performed to compare the real behavior and performance of the structures. The advantages of using dissipative connections are confirmed in a high rise flexible building. [less ▲]

The project develops two innovations. The first innovation promotes a construction measure by which the "soft storey" mechanism is obviated in the lower storeys of reinforced concrete (R.C.) frames by encasing steel profiles in R.C. columns in order to provide them with a basic reliable shear, bending and compression resistance. Tests are performed and comparison of the behaviour of reference reinforced concrete and composite specimens made. Several parameters are studied: axial load, length of anchorage, stiffeners in the panel zone, weak and strong axis bending, configurations with and without infills. The study defines design rules for steel profiles to be encased in ductile R.C. columns, formulas for the behaviour of local strut and tie mechanism in presence of infills and formulas for the calculation of the shear resistance of a composite beam-to-column panel zone in configurations without infills. The second innovation consists in using dissipative connections for diagonals of frames with concentric bracings. Two types of connections are studied: the “pin” connections, made of bent rounded or rectangular bars, and “U-device” connection, made of plates bent in U. Their behaviour is studied experimentally on connections and on complete bracings. Design rules are defined, especially for the pin connection, and fatigue curves obtained. The applicability and interest are set forward by numerical studies and comparative design of structures with classical and with dissipative connections. The innovation demonstrates a higher capacity to dissipate energy. It can be translated into higher behaviour factor q. [less ▲]

Fatigue cracks in welded connections of steel moment frame buildings submitted to earthquakes are studied. The connections of beams with thick flanges designed to resist to seismic phenomena by plastic dissipation are presented. The structural components, the materials and the crack mechanics are described. To predict the crack initiation, the knowledge of residual internal stresses, generated by the welding process, is required. So these stresses are assessed by a FEM thermo-mechanical analysis. The potential sites of crack locations are detected by using an FEM model of the connection with the continuum damage model of Lemaître and Chaboche. After these FEM analyses, new meshes with specific elements located at the potential crack locations are defined. A cohesive zone law is used to model the crack propagation. This model describes the crack growth by analyzing the energy released by the generation of the new surfaces and damage micro-phenomena behind the crack tip. A constitutive tension-separation law computes this energy. In these cases of low cycle fatigue, the damage and the cyclic loading conditions are taken into account. [less ▲]
