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: A series of four shear wall specimens was tested in order to evaluate the seismic retrofit that had been proposed for the core wall of an existing building. The core wall had nonductile reinforcing details, including lap ...

Abstract: Four different failure modes, stud shearing, concrete pullout, rib shearing and rib punching are described for metal deck stud shear connections. Equations for predicting the strengths associated with those failures are ...

Abstract: The response of slab structures after initial failure is investigated in order to determine a means of preventing progressive collapse. Analytical models for predicting the post‐failure response of slabs are presented and ...

Abstract: Analytical expressions for predicting the bond stress versus slip response and the bond stress distribution for different types of pullout tests were developed. These analytical studies were mainly based on the use of bond ...

Abstract: This paper presents the results from an experimental program that studied the effects of simulated delamination and corrosion on the structural response of six two-way slab-column specimens with details typical of older ...

Abstract: The reversed cyclic loading behavior of full-scale shear wall specimens was investigated before and after retrofit. The wall specimens were designed and detailed to simulate nonductile reinforced concrete construction of ...

Abstract: Four variable-depth pier cap beams were constructed and tested. These specimens were designed to have reinforcement details that had similar features to two different types of pier cap beams used in the Champlain Bridge ...

Abstract: Four short shear-critical rectangular columns were constructed and tested under monotonic shear loading and a constant compressive axial load. The main variable in these tests was the amount of shear reinforcement. The ...
