    Predicting Performance in Articulating Concrete Blocks: Block Geometry (Print PDH from the December 2019 issue of Informed Infrastructure)

    When left uncontrolled, water has created the deepest of canyons and destroyed countless properties. Sediment transport in streams and rivers is inevitable, but erosion must be controlled in critical areas for safety and economic reasons. Stream restoration and stabilization may require the use of armoring countermeasures to provide lateral or vertical stability to a stream. Articulated concrete block (ACB) revetment systems provide permanent erosion protection against the hydraulic forces of moving water. They are used when vegetation, soil remediation or other forms of hard armoring are unstable or unsuitable for a given hydraulic event or where the consequence of failure is not acceptable.

    Helical Piles: Best-by-Test Foundation Solution for Traffic Signs, Bollards, Emergency Call Boxes and Airport Taxiway Lights (Print PDH from the December 2019 issue of Informed Infrastructure)

    Although it’s difficult to find official estimates for the number of traffic signs in the United States, given the near-ubiquity of signs (e.g., Stop, Speed Limit, Yield, Do Not Enter, One-Way Road, Railroad Crossing, Wrong Way, No U-Turn and many others), it seems safe to put the number in the hundreds of millions. And that doesn’t count “non-sign” regulatory objects such as call boxes, bollards and airport taxiway lights.

    Precast Structural Alternatives for a Green Solution (Print PDH from the June 2019 issue of Informed Infrastructure)

    Concrete plays an integral role in urban development, from the fabrication of underground sewer lines to the construction of bridges and interstate highways. However, this development increases impervious surfaces that, in turn, generate more stormwater runoff, which often carries pollutants produced by the activities that occur on the impervious surfaces. These pollutants can include trash and debris, sediment, nutrients, dissolved metals, and petroleum hydrocarbons. Increased stormwater runoff also can erode and degrade the urban streams that ultimately receive the flow and may cause flooding issues for existing development downstream. The quality and quantity of stormwater runoff can threaten wildlife, natural systems and aesthetics. Fortunately, concrete also is part of the solution to these problems.

    Introduction to CJ Series Steel Joists in Floor Systems (Print PDH from the June 2019 issue of Informed Infrastructure)

    Composite and noncomposite steel joists are utilized to support concrete floor systems. This article highlights the use of Steel Joist Institute (SJI) CJ-Series composite joists. SJI CJ-Series composite steel joists utilize shear studs welded through the steel deck to the underlying top chord angles of the steel joists (see Figures 1 and 2). Steel joist top chords typically are fabricated utilizing hot-rolled or cold-formed steel angles. A typical 1-inch horizontal gap between the top chord angles requires that the shear studs be welded to the top chord horizontal legs on either side of this gap.

    After the concrete is placed on the steel deck and allowed to cure, the concrete slab acts as a compression chord element for the steel joist. Installed welded shear studs transfer the horizontal shear between the concrete slab and steel joist.

    Practical Design Considerations That Can Extend The Service Life Of Metal Buried Bridge And Culvert Structures (Print PDH from the April 2019 issue of Informed Infrastructure)

    Buried bridges can be described as a buried structure with a clear span of 20 feet or greater that supports an embankment and engages the passive support of the backfill material surrounding it. There are many different types of buried bridges used in highway construction. Some solutions are constructed from concrete; others utilize steel or aluminum in their designs. Buried culvert pipes utilize the same passive soil support and share many similar issues that impact the service lives of these structures.

    Buried structures frequently offer advantages over traditional slab bridges. Pavement design and maintenance are simplified with buried structures, as the same pavement design used in the roadway profile can typically be utilized over the buried structures. Buried pipes and bridges often provide accelerated design and construction schedules as compared to conventional bridges. Because buried structures help dissipate surface live loads, they frequently can utilize full inverts or shallow foundations and eliminate the need for piling or other deep foundations commonly used in conventional bridge construction. All of these advantages often lead to lower installed costs as well.

    Engineering a Permanent Road Foundation (Print PDH from the February 2019 issue of Informed Infrastructure)

    Unbound aggregate materials are the largest transportation infrastructure asset for most state and local Departments of Transportation (DOTs). This asset is used in road bases and subbases as well as for surfacing of unpaved roads. Unbound aggregate layers also are the most vulnerable transportation infrastructure, as these layers are subject to premature failure due to deterioration, contamination and adverse hydraulic conditions.

    These “out of sight, out of mind,” underappreciated and often under-engineered layers are the subject of this PDH article. The loss of support of unbound aggregate results in full-depth reconstruction, a total loss of the aggregate assets, and road downtime with traffic congestion and construction-related traffic accidents.

    Readers will be shown improved best-management design practices and how to preserve unbound aggregate assets to enhance the performance of these layers. Use of the correct aggregate and a separation/stabilization geotextile can construct a Permanent Road Foundation (PRF) so full-depth reclamation and total reconstruction may be avoided. The quality of aggregate enabled by the selection of the proper geotextile will maximize the cost effectiveness of these now-permanent road layers.

    Design Considerations for Wildlife Crossings (Print PDH from the Nov/Dec 2018 issue of Informed Infrastructure)

    The term “wildlife crossing” describes a variety of structures that are designed or retrofitted to provide safe passage for wildlife above or below a highway. Although wildlife crossing structures are not standardized designs, they can be categorized as two major types: overpasses and underpasses. Structures often are built in combination with fencing to increase their effectiveness.

    Each crossing is designed to serve the target species for a specific location or accommodate the majority of species in an area. When wildlife crossing structures are designed for motorist safety, the target species typically are large ungulates such as moose, elk or deer. Other wildlife crossings are designed for species with high conservation concern, such as salamanders, desert tortoises, flying squirrels or kit foxes.

    How to Design a Culvert Reline Project (Print PDH from the May/June 2018 issue of Informed Infrastructure)

    Culvert replacements are a common reality for all owners of drainage infrastructure and a routine part of maintenance and expansion projects on federal lands, roadways and railroads; state department of transportation (DOT) roadways; and at the local level with county, township and municipality owned transportation corridors. Fortunately, culvert rehabilitation via relining has gained momentum as a viable alternative to culvert replacement when dealing with aging drainage infrastructure. Whether an owner of a culvert wants to take a traditional design and delivery approach or conduct the work themselves, the construction methods of many reline options can be performed by parties whose normal work activities don’t include reline construction. In addition, most methods can be performed by in-house maintenance teams or entities who do more traditional open cut drainage work.

    Introduction to Designing Corrugated Metal Pipe (CMP) Stormwater Detention Systems
    (Print PDH from the May/June 2017 issue of Informed Infrastructure)

    The two essential functions of a stormwater management system are to control the 1) quality and 2) quantity of runoff leaving a site. There are various ways to do this; a common method is with an aboveground system in the form of a detention pond, but these take up usable land space. This is not a major issue in rural areas, but in urban environments, land space is expensive, and a loss of land space results in lost revenue.

    As a result, engineers and developers often turn to underground solutions, which take many forms. One of the most common is an underground detention system made from corrugated metal pipe (CMP). These systems are employed on a site to reduce the quantity of stormwater runoff leaving a site by temporarily storing the runoff that exceeds a site’s allowable discharge rate and releasing it slowly through time.

    Designing CMP detention systems is a complex task. This article is not intended to be a complete design guide; it is intended to address three questions engineers often have regarding designing CMP detention systems.

    Dams are called “installations containing dangerous forces” in International Humanitarian Law; there is potential for great destruction to people, property and the environment in the event of a dam failure. The forces that make dams dangerous also provide essential benefits such as drinking water, flood control, power production, irrigation and recreation. Holding a balance between destructive forces and essential benefits lies, to some degree, in protecting the dam from soil erosion when an overtopping event occurs.

    Helical Design: Code Compliance and Effects of Seismic Activity (Archived Webcast)

    Originally Aired March 1, 2017. This webcast has expired

    Helical piles and anchors have been used in construction applications for more than 175 years. The first recorded use of helical piles was in 1836 by Alexander Mitchell in England. The helical pile industry has seen substantial growth in the last 20 years as most practicing engineers have recognized the strength, versatility, and many applications of the system.
    The popularity of helical piles has grown so much, the International Code Council (ICC) established acceptance criteria AC358 for helical piles in 2007. ICC inducted helical piles into the International Building Code in 2009. However, helical piles were barely mentioned in undergraduate and graduate civil engineering studies.
    The presentation will cover the design, applications, and building code requirements of helical piles.
