Numerical analyses on flexural performance of prefabricated UHPC link slab

IABSE Congress Reports, 2021
<p>The expansion joints in the multi-span simply supported bridge can be eliminated by using the link slab. The ultra-high performance concrete (UHPC) with high tensile strength and crack resistance is an effective material for the link slab. However, the cast-in-situ UHPC link slab need to be cured with steam curing.

Behavior, Analysis, and Design of an Instrumented Link Slab Bridge

Journal of Bridge Engineering, 2005
Presented in this paper are the results of a research project on the monitoring and assessment of the first link slab jointless bridge in the state of North Carolina. The structure was instrumented with a remote data acquisition system and monitored for over a year.

Seismic Performance of Multisimple-Span Bridges Retrofitted with Link Slabs

Journal of Bridge Engineering, 2002
During earthquakes multisimple-span bridges are vulnerable to span separation at their expansion joints. A common way of preventing unseating of spans is to have cable or rod restrainers that provide connections between adjacent spans. Alternatively, dislocation of the girders can be controlled with a link slab that is the continuous portion of the ...

Earthquake size distribution in subduction zones linked to slab buoyancy

Nature Geoscience, 2014
Some of the most devastating earthquakes are generated in subduction zones. Analysis of the stress state of subduction zones worldwide suggests that large earthquakes are generated more frequently where a young, buoyant plate subducts.

Effect of lap reinforcement in link slabs of highway bridges

Engineering structures, 2008
This paper investigates the influence of lap reinforcement in link slabs of highway bridges under four independent boundary conditions by using a three-dimensional nonlinear finite element code based on the microplane model. Numerical solutions for load-deflection relationships, internal force distribution and failure cracking planes are presented for ...

Evaluation of Link Slab Performance on Texas Highway Bridges

Transportation Research Record: Journal of the Transportation Research Board
Multispan bridges with simply-supported girders are straightforward to construct and economical but have historically utilized expansion joints between the spans. The negative long-term impacts of expansion joints are well-documented in the literature: eventual leaking causes damage to the girder ends and substructures.

Preliminary probabilistic assessment of the seismic response of link slab viaducts

2019
Recent seismic events occurred in Central Italy drew the attention towards the resilience of the Italian road network, which is characterised by a significant number of old reinforced concrete bridges and viaducts. In this context, the fragility assessment of existing bridges is crucial, since their collapse or loss in functionality after earthquakes ...

PERFORMANCE OF LINK SLAB USING ECC AND UHPC

2019
Conventional bridge design has been challenged by durability and reliability issues due to expansion joints. Chloride-contaminated infiltration and debris accumulation in traditional expansion joints affect the bridge performance negatively. Link slab has emerging as an effective alternative in bridge rehabilitation and design by eliminating expansion ...

Early Age Cracking in a SHCC Bridge Deck Link Slab

Forensic Engineering 2015, 2015
A strain hardening cementitous composite (SHCC) with extreme tensile ductility exceeding 2% was used to construct a link slab for a jointless bridge deck on Grove Street bridge over I-94 in Michigan, USA. The superior ductility of SHCC was expected to accommodate bridge deck deformations imposed by girder deflection, concrete shrinkage, and temperature

Behavior of link slab for highway girders

A Link slab of continuous bridge deck over its adjacent span of simply supported precast girders is desirable for smooth riding due to jointless construction. Since end movements of the girders have become restraints of the slab associated with some other actions, the movements of typical highway girders of I, T, U and Box sections with different span ...
