Available in PDF, EPUB and Kindle. Book excerpt: The study presents an evaluation of the deterioration of reinforced concrete 3-sided culverts and reinforced concrete box culverts in Ohio. The Office of Structural Engineering (OSE) database for bridge size culverts (structures with a span length of 10 ft. or greater along roadway centerline) was provided to by Ohio Department of Transportation (ODOT). The database included a record based on culvert inspection data, such as general appraisal and overall culvert condition ratings. Using the provided data, Markovian deterioration models and Weibull survival analysis models were developed for cast-in-place and precast reinforced concrete 3-sided and reinforced concrete box culverts. The major findings of the study are: Data preprocessing and quality assurance should be planned and coordinated properly with a systematic procedure outlined to limit data manipulation; Markovian models can be modified to model non-standard transitions, which were encountered in the data, such as condition rating improvement and two condition ratings drop in one year; On average, cast-in-place culverts deteriorate slightly faster up to the half of the design life and maintain a slightly higher condition rating near the end of the design life compared to precast 3-sided and box culverts; On average, cast-in-place box culverts maintain a slightly higher condition rating throughout their design life compared to 3-sided cast-in-place culverts; Precast 3-sided and box culverts have a similar deterioration trend on average; The Weibull survival analysis can be highly sensitive to censored to uncensored data ratio and extreme values.

Available in PDF, EPUB and Kindle. Book excerpt: The US Federal Highway Administration (FHWA) reports 230.000 of the 577.000 bridges in the United States as deficient functionally or structurally. The majority of the structurally deficient bridges are short-span, averaging less than 15 m (50 feet) in length. Within the past two decades, prefabricated culverts have become economical alternatives for replacing deteriorating short-span bridges and cast-in-place box culverts. These prefabricated structures include reinforced concrete arches, four-sided and three-sided reinforced concrete culverts, and metal box culverts. The most commonly used type is the precast reinforced concrete culverts due to its durability, minimal field construction time, and favorable cost. Several test programs have concluded that concrete box culverts of standard ASTM C850 are structurally conservative. The strain and deflection data from model testing were found to be in good agreement with field testing of prototypes. Ihe availability of the finite element analysis programs provide the engineer an opportunity to model the actual three-dimensional geometry and boundary conditions more accurately. This research will demonstrate the use of the finite element method in analyzing me structural behavior and stress distribution of four-sided and three-sided concrete box culverts subjected to various highway loadings. A finite element modeling technique will be recommended for use by engineers. The results will assist in modeling and predicting the actual strength and behavior of a particular ASTM C 850 section or a new culvert with larger opening. Thirteen four-sided and three-sided concrete culverts will be idealized using the finite clement structural package SAP90. The following element types will be considered: (a) plate bending and stretching (shell) elements; (b)eight-node brick elements. A mesh sensitivity analysis will be performed to select a proper finite element discretization of the culverts. The culverts will be loaded with AASHTO wheel load including impact effect. Simple supports will be used at the bottom side edges. The maximum deflection in the culvert will be computed as well as the maximum moment in the upper face. The stress distribution will also be investigated. The three-dimensional cases to be analyzed will be compared to the two-dimensional frame analysis approach proposed by AASHTO (1992), and to test results from prototype culverts.

Available in PDF, EPUB and Kindle. Book excerpt: Three-sided concrete culverts can be used to replace short span bridges and multiple sections (barrels) of four-sided concrete box culverts. ASTM Standards do not specify designs for four-sided concrete box culverts with span lengths exceeding 12 ft (3.6 m) nor do they discuss the three-sided concrete culverts. This paper describes the analysis and design of three-sided flat-top precast reinforced concrete culverts with span length ranging between 14 ft (4 m) and 36 ft (11 m). It was shown that the AASHTO distribution width used in performing plane frame analysis gave similar results to the three-dimensional finite element analysis. Therefore, ten shallow structures were selected for analysis and design. The culverts were subjected to live load plus impact, dead load, and lateral earth pressure. The slab and wall thicknesses were selected so that no shear reinforcement is needed. The ultimate strength design was used to determine main reinforcing steel. AASHTO and ASTM recommendations were used to determine the reinforcing steel in transverse direction.

Book excerpt: Application of exterior coatings and membrane waterproofing on precast reinforced concrete box culverts, three-sided flat-topped culverts, and precast reinforced concrete arch and round sections is required by Ohio Department of Transportation (ODOT). Sealing and waterproofing limit the intrusion of ground water through the top of the joint and it protects the top and sides of the concrete surfaces from top-down chloride intrusion, thus extending the service life of the culvert. The intrusion of water through the joint, particularly in low cover applications, can lead to premature degradation of the reinforced concrete. This project investigated the suitability of the current exterior surface preparation of large-span reinforced concrete structures to eliminate water infiltration. Based on survey data from 24 state DOT agencies and precast concrete industry, literature review, and evaluation of ODOT's current waterproofing and joint treatment methods, successful practices are identified and recommended for repair and protection of precast concrete culverts.
