  • Northumberland Strait Crossing: Design Development of Precast Prestressed Bridge Structure
    PRECAST CONCRETE SOLVES 100-YEAR-OLD PROBLEM Northumberland Strait Crossing: Design Development of Precast Prestressed Bridge Structure The authors describe the design development process of the $840 million (Canadian dollars) Northumberland Strait Crossing Project from conceptual design in 1987 to the final project design. The 13 km (8 mile) long bridge links Prince Edward Island with New Brunswick and mainland Canada. The current design is based on main bridge spans of 250 m (820 ft) to minimize the number of piers and foundations in the Strait. Each span consists of a continuous precast, prestressed concrete variable depth double cantilever girder Barry Lester, P.Eng. with a length of 190 m (623 ft) and a drop-in segment of 60 m President (197 ft). The design took into consideration unusually heavy SLG Stanley Consultants Inc. vehicle loads, high wind loads, seismic factors, very high Calgary, Alberta icepack forces and possible ship collisions. Precast concrete Canada production began in the summer of 1994 and the main spans will be erected beginning in September 1995. The project is scheduled for completion in the summer of 1997. he Northumberland Strait gotiating the Terms of Confederation, Crossing Project (NSCP) is a the Federal Government of Canada T 13 km (8 mile) long bridge (see promised to promote efficient commu­ Fig. 1), with associated approach nication between the island and the roads and shoreside facilities, joining mainland, a promise that has been ful­ Prince Edward Island to New filled by the payment of annual subsi­ Brunswick and mainland Canada (see dies to support the island ferry service Fig.

Thorat M.Tech Student. (Civil-Structural), G.H.Raisoni College of Engineering and Management, Pune, Maharashtra, India Assistant Professor, G.H.Raisoni College of Engineering and Management, Pune, Maharashtra, India ABSTRACT: A precast segmental concrete bridge pier system is being investigated for use in seismic regions. The proposed system uses unbonded posttensioning (UBPT) to join the precast segments and has the option of using a ductile fiber-reinforced cement-based composite (DRFCC) in the precast segments at potential plastic hinging regions. The UBPT is expected to cause minimal residual displacements and a low amount of hysteretic energy dissipation. The DFRCC material is expected to add hysteretic energy dissipation and damage tolerance to the system. Small-scale experiments on cantilever columns using the proposed system were conducted. The two main variables were the material used in the plastic hinging region segment and the depth at which that segment was embedded in the column foundation. It was found that using DFRCC allowed the system to dissipate more hysteretic energy than traditional concrete up to drift levels of 3–6%. Furthermore, DFRCC maintained its integrity better than reinforced concrete under high cyclic tensile compressive loads. The embedment depth of the bottom segment affected the extent of microcracking and hysteretic energy dissipation in the DFRCC.

Lee Department of Civil and Environmental Engineering Stanford University Sarah L. Billington Department of Civil and Environmental Engineering Stanford University PEER Report 2009/109 Pacific Earthquake Engineering Research Center College of Engineering University of California, Berkeley December 2009 ABSTRACT The focus of this research is on conducting a performance-based earthquake engineering assessment of self-centering bridge columns for structural concrete bridges. Standard highway bridges in highly seismic regions are typically designed for columns to undergo large inelastic deformations during severe earthquakes, which can result in residual displacements. These residual displacements are a measure of post-earthquake functionality in bridges, and can determine whether a bridge remains usable following an earthquake. To mitigate the effects of residual displacements, a number of self-centering systems for bridge columns using unbonded post-tensioned (UBPT) reinforcing steel are proposed and investigated. The research reported herein had three objectives: (1) to assess and develop simulation methods and models that can

  • Life Cycle Assessment of Maillart's Bridges
    Politecnico di Torino École polytechnique fédérale de Lausanne Master Course in Civil Engineering Master Thesis: Life Cycle Assessment of Maillart’s Bridges Giulia Pirro Professors: Supervisor: C. Fivet and C. De Wolf R. Ceravolo Academic Year 2018/2019 Life Cycle Assessment of Maillart’s Bridges Giulia Pirro 1 Master Thesis, 2019 Life Cycle Assessment of Maillart’s Bridges Abstract Robert Maillart’s contribution to the community of civil engineers and, most of all, his crucial role in the evolution of the structural art are undeniable. He was able to merge not only mechanical efficiency with innovative solutions but also aesthetic expression as a real artist, always balancing his choices with limited resources both in terms of construction materials and costs. Following these three key parameters he succeeded in producing structures which can be considered a very good combination of structural performance and sustainability. The actual goal is to understand to what extent Maillart’s bridges are indeed sustainable in addition to be efficient and elegant. That is why performing a Life Cycle Assessment (LCA) of his bridges is a valid quantitative confirmation of his achievements. The followed procedure is, thus, based on the computation of construction materials volumes. Starting from the original drawings [1], elaborating them as 3D model, the contribution of concrete and steel is computed. Then, the volume of masonry is also calculated and, where present, the timber for the scaffolding. The goal is to compute the Global Warming Potential (GWP) of each bridge, to normalise them per deck area and to be able to compare them according to different strategies.
