Composite Bridges with Integral Abutments Minimizing Lifetime Cost
IABSE Symposium, Melbourne 2002: Towards a Better Built Environment - Innovation, Sustainability, Information Technology, 2002 The cost of maintenance is an ever- growing problem for road administrations around the world, and bridges are no exception to the rule.

Modified Sheet Pile Abutments for Low-Volume Road Bridges: TR-568, January 2012
, 2012 To date there have been few investigations of the substructures in low-volume road (LVR) bridges. Steel sheet piling has the potential to provide an economical alternative to concrete bridge abutments, but it needs investigation with regard to vertical ...

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

Soil structure interaction of integral abutment bridges
, 2014 Elimination of the bearings and expansion joints in the superstructure of integral abutment bridges offers the advantage of reducing the initial and life cycle costs of the structure.

Energy Science &Engineering, EarlyView.This study primarily investigates the optimal width for coal pillar retention in both sides of the worked‐out face section. Taking the 42201 haulage roadway of the 42201 working face at Shengxin Coal Mine as the primary research target, it analyses the optimum width for coal pillar retention through theoretical calculations, numerical simulations, and ...

Simulation of Low-cycle Fatigue in Integral Abutment Piles
IABSE Reports, 2007 <p>Integral abutment bridges are bridges without any expansion joints, and their largest benefits are the lower construction- and maintenance costs. In order to build longer integral bridges it might be necessary to allow plastic hinges to be developed in the piles. Lateral thermal movements are the major reason to plastic deformations, and since

Earthquake resistance of integral abutment bridges
, 2008 Integral abutment construction has become a popular alternative to conventional bridge construction for short and intermediate length bridges. Integral abutment construction eliminates joints and bearings which reduce long-term maintenance costs. However,

Integral Abutment-Backfill Behavior on Sand Soil-Pushover Analysis Approach
, 2005 This paper presents a study on the behavior of the abutment-backfill system under positive thermal variation in integral bridges built on sand. A structural model of a typical integral bridge is built, considering the nonlinear behavior of the piles and ...

Energy Science &Engineering, EarlyView.This study determines the impact critical stress early‐warning indicators for deep soft coal seams: 18 MPa (shallow holes), 20 MPa (deep holes), and 3 MPa/d daily stress change rate, via theoretical, experimental and simulation methods. ABSTRACT The accurate determination of early‐warning indicators for critical impact stress in deep soft coal seams is
