Comparison of Mechanistic-Empirical and Traditional Rigid Pavement Design Methods: Afyon-Emirdag Trial Section

The first rigid pavement section in Turkey under the jurisdiction of General Directorate of Highways was designed as Jointed plain concrete pavement (JPCP) according to Belgian Catalog method. This design was compared with the traditional empirical American Association of State Highway and Transportation Officials (AASHTO-93) design method and with the mechanistic-empirical (M-E) pavement design guide. Moreover, the international roughness index (IRI) values measured with intervals were compared with the predicted values of M-E analysis. According to M-E analysis, it is predicted that IRI and faulting will exceed but the cracking will be within the limit values during its service life.


Improved Seismic Response of Multisimple-Span Skewed Bridges Retrofitted with Link Slabs
Sevgili, Gizem; Caner, Alp (American Society of Civil Engineers (ASCE), 2009-11-01)
Results of a recent bridge inventory evaluation indicated that about 50% of Turkish highway bridges have more than 30 degrees of skew angle and can be classified as irregular bridges. During the recent major earthquake in Turkey, multisimple-span bridges with continuous decks and link slabs performed well even though these bridges were in the vicinity of the fault line. This study aims to evaluate the improvements in seismic response of skew bridges in terms of forces and displacements when link slabs are a...
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...
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...
Timber joint design: the geometric breakdown method
Erman, E (Informa UK Limited, 2002-11-01)
A large number of joints are developed as a result of various timber construction techniques, structural efficiency and cultural differences. Many joints are not used because they are not adapted or are inconvenient for modern manufacturing and construction technologies. Nonetheless, this construction heritage can be harnessed and adjusted for contemporary use. Significant cultural and social differences in timber jointing and construction technologies are reviewed. The Geometric Breakdown Method is develop...
Rating and reliability of existing bridges in a network
Akgül, Ferhat (American Society of Civil Engineers (ASCE), 2003-11-01)
Currently, the load rating is the method used by State DOTs for evaluating the safety and serviceability of existing bridges in the United States. In general, load rating of a bridge is evaluated when a maintenance, improvement work, change in strength of members, or addition of dead load alters the condition or capacity of the structure. The AASHTO LRFD specifications provide code provisions for prescribing an acceptable and uniform safety level for the design of bridge components. Once a bridge is designe...
