Abstract

Reinforced concrete (RC) culverts under high fill have been widely used in the construction of expressways and railways. Based on the results of a field survey, various types of structural damage to RC culverts occur during construction and service periods. In this study, numerical simulation and field tests were conducted to investigate the impact of soil properties on the structural integrity of RC culverts under high fill. Important factors that influence culvert integrity, such as ground bearing capacity and ground treatment, have been analyzed in detail. Research findings indicate that damage to RC culverts under high fill is not typically caused by failure to the subgrade layer under the culvert foundation, due to the beneficial effects of foundation depth, foundation width and subgrade layer consolidation. Structural damage is probably caused by improper ground treatment strategies. Proper strategies for preventing integrity problems are recommended based on the research. (C) 2013 Elsevier Ltd.

Deep foundation

A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper.

Shallow foundation

A shallow foundation is a type of building foundation that transfers structural load to the earth very near to the surface, rather than to a subsurface layer or a range of depths, as does a deep foundation. Customarily, a shallow foundation is considered as such when the width of the entire foundation is greater than its depth. In comparison to deep foundations, shallow foundations are less technical, thus making them more economical and the most widely used for relatively light structures.

Structural integrity and failure

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. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively.

Reusability assessment of reinforced concrete components prior to deconstruction from obsolete buildings

Maléna Bastien Masse, Julie Rachel Devènes, Corentin Jean Dominique Fivet

A large part of building demolitions is motivated by purely socio-economic reasons. Hence, about-to-be-demolished structures, commonly made of reinforced concrete, very often present no or little degradation. When adaptive reuse of the entire building is n ...
