Enhancement of riveted steel bridges by adding a trough in UHPFRC acting in composite action

Riveted railway bridges are commonly considered as being “old”, having fatigue damage and are therefore replaced. While this practice should be by now obsolete by using novel engineering methods like structural monitoring, prolongation of the service durat ...

Optimization of multi-directional fiber architecture for resistance and ductility of bolted FRP profile joints

Thomas Keller, Lulu Liu, Xin Wang

In view of the low structural efficiency of bolted joints in pultruded fiber-reinforced polymer (FRP) profiles with mainly unidirectional (UD) fiber architecture, off-axis plies were considered as an effective way to improve bolted joint performance. An ex ...

A Calculation Method for Interconnected Timber Elements Using Wood-Wood Connections

Yves Weinand, Julien Gamerro, Jean-François Bocquet

Wood-wood connections, widely used in the past, have been progressively replaced by steel fasteners in timber constructions. Currently, they can be manufactured and implemented more efficiently thanks to digital fabrication techniques. In addition, with th ...

Modelling Workflow for Segmented Timber Shells using Wood-wood Connections

Yves Weinand, Julien Gamerro, Nicolas Henry Pierre Louis Rogeau, Petras Vestartas

This paper presents a modelling method based on planarization for double-curved segmented timber shell made from quad polygons and assembled by wood-wood connections. The inspiration is taken from timber dome structures, where solid timber walls were built ...

Enhancing Punching Strength and Deformation Capacity of Flat Slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Punching reinforcement systems have significantly developed in recent years as they allow enhancing the punching resistance of slab-column connections as well as their deformation capacity. These systems, with varying geometry and layout, normally consist ...

Shell Modelling Strategies for the Assessment of Punching Shear Resistance of Continuous Slabs

Aurelio Muttoni, Raffaele Cantone, Beatrice Belletti

The punching shear resistance formulation provided by Model Code 2010 is calibrated on the basis of experimental tests on isolated slabs supported on columns. According to Level of Approximation approach, several quantities are required for the design punc ...

Bonded sleeve connections for joining tubular GFRP beam to steel member: Numerical investigation with experimental validation

Zhujing Zhang, Yu Bai, Chao Wu

This paper investigates an innovative bonded sleeve connection for joining tubular GFRP and steel members. Experimental results focused on mechanical responses of beam-to-column specimens using bonded sleeve connections and conventional steel angle connect ...

Variability of the pullout strength of cancellous bone screws with cement augmentation

Dominique Pioletti

Background: orthopaedic surgeons often face clinical situations where improved screw holding power in cancellous bone is needed. Injectable calcium phosphate cements are one option to enhance fixation. Methods: paired screw pullout tests were undertaken in ...

A critical examination of the size effect correction for welded steel tubular joints

Alain Nussbaumer, Luís Costa Borges, Ann Schumacher

Welded circular hollow section (CHS) joints typical to bridge construction have been examined in an experimental, numerical, and analytical study with respect to their fatigue strength. Evidence from this study has indicated lower fatigue strength for join ...

Size effects in the fatigue behaviour of tubular bridge joints

Luís Costa Borges

A critical aspect in the design of tubular bridges is the fatigue performance of the structural joints. Economic viability depends on it. Lower fatigue strength for joints with thicker failing members was observed in welded joints typical to the bridge app ...

A probabilistic model for determining the effect of post-weld treatment on the fatigue performance of tubular bridge joints

Alain Nussbaumer, Scott Walbridge

Herein, a probabilistic model for predicting the effect of post-weld treatment on the fatigue performance of the welded joints in tubular truss bridges is described. Specifically, a probabilistic LEFM-based model is first developed for the fatigue analysis ...

A probabilistic study of fatigue in post-weld treated tubular bridge structures

Scott Walbridge

In the design of tubular bridges, engineers have found the fatigue performance of the joints to be a critical aspect that may have a significant impact on the economic viability of these structures. In looking for ways of improving this performance, the us ...
