Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of corrugated metal pipe in the late 1890s, there has been a continuing interest in proper pipe usage for maintenance purposes. Early methods of design were truly "rule of thumb" and were developed through "failure criteria." Refinements of these methods resulted in a set of systems that were very effective in dealing with pipe problems. However, the building of the Institute Highway System brought with it a need to develop new approaches that would incorporate the latest soil-structure interaction theories and be applicable to the larger structures, higher embankments, and new materials. Better inspection and construction control are considered requisite to the utilization of more refined theories. Practice in the design and construction of culverts continues to improve, but, because many organizations have not been able to keep up with or apply the latest theories, the Highway Research Board Committee on Subsurface Soil-Structure Interaction organized a symposium to assess the state of the art and to delineate problems needing further attention.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Heger's pressure distributions are considered a fundamental tool in the design of reinforced concrete culverts per the direct design method. However, there are some factors known to affect soil-structure interaction that are neglected when utilizing Heger's pressure distributions. These factors include the effect of the trench geometry, the relative stiffness of the existing and backfill soil, and the burial depth of the structure. This thesis presents a detailed finite-element analysis parametric study that investigates the accuracy and applicability of Heger's pressure distributions for culverts in partial trench installations when the aforementioned factors are considered. Additionally, a detailed pseudo-static finite-element analysis parametric study investigating the applicability and accuracy of the simplified seismic load combination presented in the Canadian Highway Bridge Design Code is presented."--Leaf ii

This book was released on 2018-05-24 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings of the EPS 2018: 5th International Conference on Geofoam Blocks in Construction Applications, held in Kyrenia, Northern Cyprus on May 9 to 11, 2018, present a collection of contributions on the state-of-the-art of research and applications relating to geofoam. Geofoam researchers, consultants, molders, contractors and practitioners from all around the globe discuss the recent developments and future trends of expanded polystyrene (EPS)-block geofoam technology and its construction applications. EPS’18 contributes to the development of geofoam applications, following on from successful conferences in Oslo (1985), Tokyo (1996), Salt Lake City (2001) and Oslo (2011). The book discusses topics including, but not limited to, current use of geofoam, design specifications, applications, new concepts, material properties, modeling and specific topics in geofoam blocks in construction applications.

Available in PDF, EPUB and Kindle. Book excerpt: Failures of box culverts under static and earthquake loads can cause significant economic loss. Therefore, it is important to investigate the soil-culvert interaction of box culverts to understand their responses to such loads. The response of buried box culverts is a complex soil-structure interaction problem, where the relative stiffness between the soil and the structure is a critical factor. Soil arching is an important aspect of the soil-culvert interaction problem, and results in the redistribution of free-field stresses due to the presence of buried structures and leads to an increase or decrease in the loading around box culverts. A series of static and seismic scaled physical model centrifuge tests were performed to investigate the soil culvert interaction. Two different box culvert thicknesses and two Nevada sand relative densities were used to explore the interaction between the sand and box culverts under a wide range of different conditions. The static loading consisted of the soil self-weight of and the surcharge from a surface foundation, while the seismic loading considered the application of seven earthquake shaking events for each test. Several sensors were used in these tests, including tactile pressure sensors, LVDTs, accelerometers and strain gauges. A newly developed method for installing the strain gauges inside the box culvert model is introduced. The responses of the box culvert have been compared for all of the loading conditions. It was observed that the kinematic soil culvert interaction due to the presence of a box culvert, as well as the surface foundation, had a significant effect on reducing the peak ground acceleration at the surface when compared to the free-field peak ground acceleration. The kinematic interaction can provide up to a 50% reduction and is dependent on the amplitude of the input motion at the base of the model. Small values for the rocking of the box culvert and surface foundation were also observed, and their values changed with the amplitude of the input motion. The values observed for the foundation were higher than those for the culvert, due to the soil confinement. The lateral movement of the foundations increased as the peak ground acceleration at the base of the model increased. The racking deformation ratio of the culvert was found to change with the thickness and therefore the relative stiffness of the culvert and the soil density. Soil pressures measured by different methods were in good agreement and those obtained from the tactile sensors can be considered to bound the expected behaviours. The soil pressure observed on the culvert top slab had a parabolic shape, i.e., higher values at the edges and lower at the center than the theoretical vertical soil pressure. On the side wall, the horizontal soil pressure increased with depth. The soil-culvert interaction factors decreased at the center and increased at the edges of the top slab, as the thickness and the relative stiffness of the culvert decreased. The seismic analysis showed that the seismic bending moment increased as the peak ground acceleration at the model base and the relative stiffness of the culvert increased. The static and seismic responses of the box culvert were analyzed using the finite difference code FLAC 2D and the results matched the experimental responses. The validated numerical model was then used to perform a parametric study, to evaluate the effects of: culvert geometric parameters, foundation locations and soil properties for the static loading and only the culvert geometric parameters for the seismic loading. The results have been evaluated for bending moment, soil pressure and soil culvert interaction factors. Based on these analyses, charts and equations are presented to help in assessing the design values of the static soil pressure, static bending moment, and the seismic bending moments around box culverts.

Available in PDF, EPUB and Kindle. Book excerpt: To obtain a better understanding of the stresses acting on cast-in-place concrete box culverts, and to investigate the conditions which resulted in a culvert failure under about 12 meters of backfill, two sections of a new culvert were instrumented. The measured earth pressure distribution was found to depend upon the height of the embankment over the culvert. For low embankment heights (less than one-half the culvert width), the average measured vertical earth pressures, weighted by tributary length, were about 30% greater than the recommended AASHTO pressures. The measured lateral pressures were slightly greater than the AASHTO pressures. As the embankment height increased, the measured weighted average vertical stress exceeded the AASHTO pressures by about 20%. Lateral pressures which exceeded the vertical pressures were recorded at the bottom of the culvert walls, and small lateral pressures were recorded on the upper locations of the wall. The high lateral pressures at the base of the wall are consistent with the results from finite element analyses with high density (modulus) backfill material placed around the culvert.
