Book excerpt: A two-dimensional nonlinear p-version finite element method is developed for the analysis of boundary value problems relevant to elastomeric bridge bearings. The method incorporates polynomial shape functions of the hierarchic type for the modeling of large-deformations rubber elasticity. In addition, a frictional-contact algorithm based on a penalty formulation and suitable for the interaction of the pad with rigid flat surfaces is derived and implemented. The J sub 2 flow theory with isotropic hardening is utilized to model the reinforcing steel as a bilinear elastoplastic material. Examples are presented to illustrate the performance of the element and some guidelines for the selection of appropriate orders of interpolation and integration rules. The results of a study performed to examine the effects of several design parameters of the bearing are presented. Comparisons with experimental findings are shown. A dynamic lumped model for the walking of the bearing is developed. Viscous frictional interfaces with the girder and the abutment are included. Several cases are analyzed to investigate the factors that affect this phenomenon.

This book was released on 2020 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastomeric bearings have been used in bridges for more than 60 years. They are economical, durable, require minimal maintenance, and are suitable for larger rotations. The AASHTO LRFD Design Specifications provide two different design approaches for elastomeric bearings: Method A and Method B. Method A is simple and rational whereas Method B is complex but more realistic. Method A was proposed with the goal to make it quick and be consistent with Method B. The study has developed solution spaces for these methods which not only assist the analysts to understand the inter-relationship between these methods but also check their compatibility. The analysis of solution spaces demonstrated the possibilities of the cases where bearings designed using Method A fails to satisfy the provisions of Method B.These cases result in inconsistent design and cause difficulties to the designer. Thus, a profound analysis of the behavior of elastomeric bearings is required. For the purpose, nonlinear finite element models are developed using Abaqus/CAE 2019 and are validated with the experimental tests. The results from validated finite element models are compared with analytical closed-form solutions and current AASHTO design methodologies to check their accuracy and recommend a suitable analytical model for a more realistic design.

This book was released on 1995 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to analyze elastomeric bearing performance on the basis of elastomer hardness, shape factor, reinforcing shim orientation, degree of taper and compressive stress level with the goal of developing a simple design procedure which standardizes as many of those parameters as possible. Particular emphasis was placed on comparing the behavior of flat and tapered bearings. Experimentation included shear, compressive, and rotational stiffness tests, shear and compression fatigue loading, long-term compressive loading, and tests to determine compressive stress limits.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of tests and analyses performed on elastomeric bridge bearings. The focus of this research was the measurement of bearing deformations in the field and assessment of the feasibility of using instrumented elastomeric bearings to monitor bridge condition. The bearing deformations were successful measured in the field during the deck concrete pour and a static truck test. Shear, compression, rotation, and fatigue tests have been carried out in the laboratory and at the manufacturer's facility. Full scale bearings (shape factor 11) were tested at the manufacturer and installed in the field. Model bearings (shape factor 11 and one-quarter the plan area of the full scale bearings) were tested at the manufacturer and in the laboratory. Test bearings (shape factors 5,7, and 10) were tested in the laboratory. The bearing material was 50 Durometer neoprene. The analyses support the testing and considered the bridge-bearing system. The stiffnesses of the bearings are explicitly included in the analyses. A singular characteristic of this experimental research is the focus on the in-service behavior of the bearings.

Available in PDF, EPUB and Kindle. Book excerpt: Based on a study of seismic isolation and energy absorption of elastomeric pad bearing and TPFE bearing, the vibration equations of nonlinear seismic response for continuous girder bridges have been derived. The nonlinear characteristics for rubber bearings are accounted for, and related commercial software EARGB-RB-2 is developed by the authors. This paper deals with the behaviour and regular pattern of seismic responses of continuous girder bridges with rubber bearings, and illustrates the proposed technique with the help of examples.
