Evaluation of low-temperature test methods for elastomeric bridge bearings



Evaluation of Top Flange Bracing Systems for Curved Box Girders
Topkaya, Cem; Williamson, Eric B. (American Society of Civil Engineers (ASCE), 2005-11-01)
In recent years, steel trapezoidal box girders for curved highway interchanges have become popular. For these bridge systems, significant steel girder cross-sectional stresses occur during the concrete casting sequence. To help resist construction loads, a lateral truss system is installed at a level close to the top flanges to form a "pseudo-closed" section, which has a higher torsional stiffness than an open U-section. Several recent incidents, ranging from the buckling of individual bracing members to th...
Investigation of the Applicability of AASHTO LRFD Live Load Distribution equations for Integral Bridge Substructures
Erhan, Semih; Dicleli, Murat (SAGE Publications, 2009-08-01)
In this study, applicability of the AASHTO LRFD girder live load distribution equations (LLDEs) for integral bridge (IB) abutments and piles is investigated. For this Purpose, numerous 3-D and corresponding 2-D structural models of typical IBs are built and analyzed under AASHTO LRFD live load. In the analyses, the effect of various superstructure properties such as span length, slab thickness, girder spacing and stiffness are considered. The results from the 2-D and 3-D analyses are then used to calculate ...
Application of ring beam stiffness criterion for discretely supported shells under global shear and bending
Topkaya, Cem (SAGE Publications, 2018-12-01)
Silos in the form of a cylindrical metal shell are commonly elevated to provide access to the space beneath. In general, a few discrete column supports at evenly spaced intervals are commonly utilized. The presence of discrete supports results in circumferential non-uniformity in the axial compressive stress above the support. Depending on the size of the structure, several different support arrangements may be chosen. A stiff ring beam is utilized in larger silos to transfer and evenly distribute the discr...
Experimental Determination of Resistance Characteristics of Support Details Used in Prestressed Concrete Bridge Girders
Baran, Eray; French, Catherine; Schultz, Arturo (American Society of Civil Engineers (ASCE), 2009-09-01)
Static load tests were performed on support details used at the ends of prestressed concrete pedestrian bridge girders to determine the resistance characteristics of girder supports in the direction perpendicular to the longitudinal axis of the girders. The specimens tested represent support details that have also been widely used in prestressed concrete highway bridges in Minnesota and in other states. Two specimens, one representing the free-end detail and one representing the restrained-end detail were s...
Comparative Study on the Effect of Number of Girders on Live Load Distribution in Integral Abutment and Simply Supported Bridge Girders
Yalcin, O. Fatih; Dicleli, Murat (SAGE Publications, 2013-06-01)
In this study, the effect of the number of prestressed concrete girders on the distribution of live load effects among the girders of integral abutment bridges (IABs) and simply supported bridges (SSBs) is investigated. For this purpose, two and three dimensional finite element models (FEMs) of several single-span IABs and SSBs are built and analyzed. In the analyses, bridges with various superstructure properties, such as span length, girder type and size, slab thickness are considered. The finite element ...
