Abstract: This paper describes the collapse during construction of a precast concrete girder bridge crossing Highway 15, north of Montréal. The bearing conditions for the girders at the time of collapse are discussed. The tie rods ...

Abstract: This paper presents two analysis methods for the in-plane seismic response of steel multitiered braced frames (MT-BFs) with three or more tiers: (1) a substructuring technique; and (2) a stiffness analysis method. ...

Abstract: A method based on elastic stability analysis to design bolted single shear lap (SSL) connections, which are traditionally used for hollow structural section (HSS) bracing members, is proposed in this paper. The method ...

Abstract: The influence of mass irregularity on building seismic response is examined for an eight-story concentrically braced steel frame with different setback configurations resulting in sudden reductions in plan dimensions and ...

Abstract: An experimental program was undertaken to investigate the inelastic seismic response of metal deck roofing systems. The load carrying capacity of roof diaphragms for low-rise steel buildings, subjected to lateral loads ...

Abstract: This paper examines the seismic response of 2-, 4-, 8-, 12-, and 16-story steel framed buildings with self-centering energy dissipative (SCED) bracing members. The structures are assumed to be located in Los Angeles, ...

Abstract: Use of passive energy dissipators is emerging as an accepted practice for the seismic design and retrofit of civil engineering structures. One such new device, based on a self-centering friction mechanism is investigated ...

Abstract: Analytical models are proposed to predict the compressive resistance of discontinuous bracing members in steel X-braced frames when governed by flexure of the connecting plates at the mid-connections. The connections are ...

Abstract: A comprehensive study has been conducted to investigate the long-term behavior and strength of partially encased composite columns made with thin-walled welded I sections stiffened with transverse links. The paper presents ...
