Center for Urban and Regional Analysis logo. The Center for Urban and Regional Analysis (CURA) is an interdisciplinary research organization of Ohio State University.CURA's mission is to serve as a bridge across academia, industry, and the policy sector by providing spatial analysis of economic, social, environmental, and health issues in urban and regional settings in Ohio and beyond.

In solid mechanics, the Johnson–Holmquist damage model is used to model the mechanical behavior of damaged brittle materials, such as ceramics, rocks, and concrete, over a range of strain rates. Such materials usually have high compressive strength but low tensile strength and tend to exhibit progressive damage under load due to the growth of ...
The STAAD.Pro Advanced Slab Design workflow is an integrated tool that works from within the STAAD.Pro environment. Concrete slabs can be defined, and the data can be transferred to RAM Concept. The data passed into RAM Concept includes the geometry, section and material properties, loads and combination information, and analysis results.
The Interurban Bridge, also known as the Ohio Electric Railroad Bridge. is a historic interurban railway reinforced concrete multiple arch bridge built in 1908 to span the Maumee River joining Lucas and Wood counties near Waterville, Ohio. The span was once the world's largest earth-filled reinforced concrete bridge. [2]
No record exists of the first calculations of the strength of structural members or the behavior of structural material, but the profession of a structural engineer only really took shape with the Industrial Revolution and the re-invention of concrete (see History of Concrete). The physical sciences underlying structural engineering began to be ...
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
The rate of flow of the ions between the anode and cathode areas, and therefore the rate at which corrosion can occur, is affected by the resistivity of the concrete. [5] To measure the electrical resistivity of the concrete a current is applied to the two outer probes and the potential difference is measured between the two inner probes.
