Updating Bridge Reliability Based On Bridge Management Systems Visual Inspection Results, Allen C. Estes, Dan M. Frangopol
Updating Bridge Reliability Based On Bridge Management Systems Visual Inspection Results, Allen C. Estes, Dan M. Frangopol
Architectural Engineering
Bridge management systems have become increasingly sophisticated over the past decade and provide valuable information about the structural condition of all bridges in the national database. At the same time, reliability methods have gained increasing prominence and are used to forecast life-cycle performance over many decades of structural life. Such reliability analyses need to be updated based on the results of inspections. Specifically targeted nondestructive evaluations are the preferred solution, but are not always available for every bridge. This paper examines how the visual inspection data provided from bridge management systems already in place can be used to update the …

Correlating Off-Axis Tension Tests To Shear Modulus Of Wood-Based Panels, Edmond P. Saliklis, Robert H. Falk
Correlating Off-Axis Tension Tests To Shear Modulus Of Wood-Based Panels, Edmond P. Saliklis, Robert H. Falk
Architectural Engineering
The weakness of existing relationships correlating off-axis modulus of elasticity E to shear modulus G12 for wood composite panels is demonstrated through presentation of extensive experimental data. A new relationship is proposed that performs better than existing equations found in the literature. This relationship can be manipulated to calculate the shear modulus G12 of orthotropic specimens such as wood-based panels solely from off-axis tension (or compression) tests. The proposed relationship reduces to classical theory for the isotropic case. In all cases tested, the newly proposed relationship is a better fit to the data than the traditional orthotropic elasticity equation.
Finite Element Simulation Of Retrogressive Failure Of Submarine Slopes, A. Azizian, Radu Popescu
Finite Element Simulation Of Retrogressive Failure Of Submarine Slopes, A. Azizian, Radu Popescu
Architectural Engineering
To simulate earthquake-induced, retrogressive submarine slope failures, element removal capabilities of a finite element program are used to model a soil mass that fails and then flows away, causing upper parts of slope to fail retrogressively due to loss of support. It is explained how an initial failure leads to subsequent failures of a flat or gently sloping seafloor. Effects of a silt layer and gently sloping seafloor on the extension of retrogression in a sand deposit are studied. The extension of failure increases significantly for a gently sloping seafloor with the presence of a silt layer.
Hershey Arena: Anton Tedesko’S Pioneering Form, Edmond P. Saliklis, David P. Billington
Hershey Arena: Anton Tedesko’S Pioneering Form, Edmond P. Saliklis, David P. Billington
Architectural Engineering
Civil engineering structures are part of our cultural heritage. The story of who we are can be told, in part, by what we have built. There have been pivotal moments in civil engineering design history wherein a master engineer creates a pioneering structure. One major example is Anton Tedesko’s 1936 Hershey Ice Arena, the first large-scale thin shell concrete roof in the United States. Tedesko left all his papers, including the original design and analysis calculations of the Hershey shell, to the Princeton Maillart Archives. These documents, as well as other archival materials and photographs, provide insight into the design …
Finite Element Modeling Of Guastavino Tiled Arches, Edmond P. Saliklis, S. J. Kurtz, S. V. Furnbach
Finite Element Modeling Of Guastavino Tiled Arches, Edmond P. Saliklis, S. J. Kurtz, S. V. Furnbach
Architectural Engineering
An investigation of Rafael Guastavino's arches has been conducted by means of finite element modeling and laboratory experimentation. A novel method of modeling laminated masonry tile construction via the finite element method has been devised. This technique takes advantage of the layered shell element features found in commercially available finite element programs. Historical Guastavino tiles have been tested to obtain material properties. These modem techniques have been employed in conjunction with Guastavino's original empirical design criteria to provide a better understanding of these historically significant structures.
