What do you think of WyoDOT's Brass Culvert. I am currently designing a 5 cell RCB and I haven't found any program that will design that many cells. We also use this to do our load rating of box culverts. Our DOT uses this program also. One of the precasters here in the area also uses BRASS Culvert to check the designers numbers before casting too. Our DOT has said that the rating module in BRASS is VERY conservative. Come up with the loads by hand and model the box with the appropriate load combinations in your STAAD, RISA, VA, etc., and then a few quick hand calcs for the design checks. I don't have a moving load generator so maximizing the live load effects for the design truck, tandem, double tandem and permit vehicle is tedious.

Many highway-related structures, including culverts, are deemed to be in a state of disrepair or obsolescence. Culverts serve the dual purpose of conveying water under the highway while carrying traffic over streams and ditches. As such, they affect and influence the safety of the public traversing these highways while also ensuring proper drainage and hydraulic performance. (Photos 1 and 13)It is important that all those who inspect highways are trained to understand the key factors related to culvert inspection and maintenance. Alternatively, the option of contracting with outside experts should be considered.The focus is on factors that influence the structural integrity of the culvert and items affecting efficient hydraulic performance. Methods of evaluation and discussion of potential solutions such as replacement, repair and maintenance also are presented.The embankment may be used for a roadway, highway, street, railroad, access to an industrial facility or a private business, etc.For states such as Ohio with more than 30,000 bridges, or Texas with more than 50,000 bridges, the number of culverts is overwhelming.This can be a single span or several openings passing the same body of water, added together. (Photo 2) Conversely, the FHWA considers structures with a span equal to or greater than 20 feet to be a bridge. (References 5b) All bridges should be listed in the National Bridge Inventory (NBI), a database comprised of each state's department of transportation (DOT) bridge inventory. (References 5c)Culverts are classified as rigid, semi-rigid or flexible based on their material type, how they carry load and to what degree they rely on the surrounding soil envelope for support. http://www.oglethorpeclub.org/~oglethor/UserFiles/carvox-2-way-alarm-manual.xml This article provides an overview of the practical design and performance differences to consider. However, detailed culvert design factors and procedures are readily available through the listed references. Those designing, inspecting, evaluating and specifying culverts must understand the functional differences between culvert types and the degree of dependence upon the in-place strength and physical characteristics of the underlying and surrounding soil.Unlike the well-established National Bridge Inventory (NBI) and the required inspection intervals for all U.S. bridges, culverts have had less regular attention paid to their in-place performance. In many cases, culvert inspection happens as a result of problems with the roadway above.Although the FHWA suggests that states develop and implement such a program, a mandate has not been issued to state DOTs. As such, culvert inspection often falls to established bridge and highway inspection personnel, some of who may not have the extensive knowledge specifically needed to understand and appreciate the nuances and key, relevant factors associated with culvert inspection.Collecting relevant data leads to a reliable evaluation, and ultimately a reliable load rating. A trained and competent culvert inspector will observe, and, when possible, measure and obtain all of the following key culvert data:Imagine a state DOT having 100,000 culverts and devoting the required man hours to accomplish this comprehensive approach on a routine basis. Consequently, a detailed approach to culvert inspection is often not taken or is outsourced to non-DOT consultants.The inspection team needs to be properly trained in confined space entry. Tripping and slipping hazards exist. Conditions may be hazardous. Slope stability and negotiating embankments with potentially unstable footing and vegetation calls for proper safety measures. Working in teams or in tandem is recommended. http://www.statcardsports.com/node/8870 This article will not attempt to list or describe all of the relevant issues and necessary safety precautions. It is recommended that inspection personnel follow OSHA and other safety guidelines for such work.It is expressed as a rating factor (RF) or expressed in terms of tonnage for a particular vehicle. The RF is simply the structure's capacity at material yield (Capacity) less the dead load (DL) divided by the live load (LL) plus Impact as appliable. Restated, the structure must have enough strength remaining after the dead load is subtracted to carry the live load. Otherwise, this rating factor is less than one (1) and problematic, requiring a reduction in the applied load to keep the culvert in service.The longer a culvert has been in service, the more likely the field characteristics show signs of deterioration that ultimately reduce the culvert's design capacity, resulting in a lower load rating than originally designed. The question becomes: Is there still enough remaining capacity for the culvert to safely carry the required in-service loads?In general, new culvert and bridge designs completed since October 1, 2010, are rated using the LRFR method. The NBI ratings are based on the HL-93 culvert and bridge design loads, and should be reported as a rating factor (References 3b). For new bridges designed prior to October 1, 2010, where the design was based on Allowable Stress Design (ASD) or Load Factor Design (LFD), the NBI ratings can be based on either LFR or LRFR. The rating factors are based on AASHTO HS-truck loading and reported in tons when using the LFR method. Culverts that have been in the ground at least 30 years also use LFR or LRFR even though they were designed using allowable stress design.The National Corrugated Steel Pipe Association (NCSPA) Data Sheet 19 (References 6b with link) serves as the basis for load rating buried flexible corrugated metal pipe. Many DOTs, including Ohio, have modified this data sheet to include the LRFR method. http://hwprigging.com/images/ca-1010-manual.pdf A spreadsheetdriven solution is available from the Ohio Department of Transportation (References 9).BRASS-CULVERT analyzes and designs one- to four-barrel reinforced concrete rigid or flexible box culverts, with or without bottom slabs. End skews can be defined. Wall and slab thicknesses may be specified or set by the program.Additional resources also are available though trade organizations, such as:The structural capacity and hydraulic functionality of the culvert will be governing factors when it comes to making decisions as to the proper course of action for deficient or deteriorated culverts. Other key factors include the safety and convenience of the traveling public and adjacent property owners; traffic volume and vehicle loading details; economic considerations and budgetary constraints; and the feasibility of various repair versus replacement options.Partial rehabilitation or repair, temporary bracing when appropriate, invert paving, etc. — perhaps combined with a posted load reduction — could be employed as methods to keep a culvert in service and functional until more permanent measures can be undertaken. Transportation officials must consider the safety and conveniences of the travelling public, assess the feasibility of various repair methods, take into account the effects of any posted load reductions and evaluate the economics and practicality of various rehabilitation methods compared to total replacement. Often relining of a deteriorated culvert is chosen as the most logical and appropriate means of ensuring continual performance with minimal disruption. https://www.ideaklinik.com.tr/wp-content/plugins/formcraft/file-upload/server/content/files/1629c6947c334d---Cpr-manuals-heartsaver.pdf (Photos 10, 11 and 12)Careful and controlled removal of the existing pavement section and installing a reinforced concrete load relief slab over the culvert perhaps combined with higher strength fill such as a concrete slurry or a controlled low strength mortar fill for the upper section of the select fill zone may be an option to consider when dealing with situations involving less than the required minimum cover.There is a percentage of installed culverts that are operating at diminished functionality from the perspective of structural performance and hydraulic efficiency. As such, it is highly recommended these culverts be properly inspected and maintained by state DOTs and other roadway and public transportation departments, agencies and officials to ensure satisfactory performance and safety. Unfortunately, typical bridge inspection procedures and guidelines may not be adequate for many culverts. Often there are not sufficient personnel to carry out such detailed inspections and evaluations.Key factors influence the choices made regarding the feasibility of various repair versus replacement options.He has 36 years of experience in the corrugated metal pipe industry and is an active member of various technical organizations including ASCE, AREMA, NCSPA and ASTM.FHWA-IP-86-2, July 1986.

Box 41023, Lubbock, TX 79409.The basics of culvert load rating are discussed and are followed by a history of culvert design policy and the challenges created by the use of culvert standard designs. A population of Texas Department of Transportation CIP RC standard culvert designs developed between 1930 and 1980 was load rated by using AASHTO policy guidance and a two-dimensional model of direct stiffness structural demand for a full range of cover soil depths. This analysis resulted in a set of 1,081 relationships of load rating versus cover soil depth. Three typical relationships of rating versus depth are illustrated and described in detail. The distribution of characteristic relationships of rating versus depth on the basis of culvert geometry, design cover soil depth, and design era is explored. Cover soil depth is shown to be a critical parameter that must be explicitly considered for the intelligent load rating and design of RC box culverts. References 1.
