Nonlinear analysis of the end zones of prestressed concrete girders [PDF]
, 2017 Pretensioned concrete girders have been used for many years in construction. Nevertheless, optimization is still possible, especially regarding the anchorage zones.

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders
Structural Concrete, EarlyView.Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate
Structural Concrete, EarlyView.Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Why did modern post-tensioned floors flourish in the us and not in europe -a matter of tradition? [PDF]
, 2016 Unlike in Europe, prestressed concrete with post-tensioned reinforcement came to be a standard technique in building construction in the US. Kenneth Bondy has been the only one who has made a significant contribution to clarify why this occurred, by ...

Modeling for assessment of long-term behavior of prestressed concrete box-girder bridges [PDF]
, 2018 Large-span prestressed concrete (PC) box-girder bridges suffer excessive vertical deflections and cracking. Recent serviceability failures in China show that the current Chinese standard modeling approach fails to accurately predict long-term ...

Structural Concrete, EarlyView.Abstract Compression field approaches such as the Cracked Membrane Model with fixed, interlocked cracks (CMM‐F) are efficient tools for the mechanical modeling of reinforced concrete elements, providing the mechanical model σ=fε$$ \boldsymbol{\upsigma} =f\left(\boldsymbol{\upvarepsilon} \right) $$ required for finite element analyses.

Mechanical component screening for scanner [PDF]
, 1972 The critical mechanical components of the scan mirror mechanism are described and their evaluation and screening procedures are discussed. A bumper/damper unit is used in the design to reverse motion of the mirror and effect scan and retrace cycles.
