Utah Structural 30 PDH Discount Package 3

This online engineering PDH course provides the practicing engineer with the background required to understand and use the design rules for fatigue resistance that are currently a standard part of design codes for fabricated steel structures. 

Fatigue in metals is the process of initiation and growth of cracks under the action of repetitive tensile loading. If crack growth is allowed to go on long enough, failure of the member can result when the uncracked cross-section is sufficiently reduced such that the member can no longer carry the internal forces from the crack which extends in an unstable mode. The fatigue process can take place at stress levels that are substantially less than those associated with failure under static loading conditions. The usual condition that produces fatigue cracking is the application of a large number of load cycles.

This online engineering PDH course delivers the best practices for repair and retrofit of fatigue cracks in steel bridges.

This course is also a guide for owners and consulting engineers to use for design and detailing of repairs and retrofits for fatigue cracks. It should be used in conjunction with existing specifications, codes, and engineering judgment. In addition to designing and executing the repairs and/or retrofits, there are numerous other steps involved in the inspection and assessment of a cracked bridge member.

When cracks are discovered in bridge elements (members or connections) in service, fatigue is usually the cause. Fatigue is the formation of a crack due to cyclic service loads. Fracture may be defined as rupture in tension or rapid extension of a crack, leading to gross deformation, loss of function or serviceability, or complete separation of the component. Periodic in-service inspection provides an opportunity to assure safety by detecting cracks before they grow to a critical size. The Federal Highway Administration has mandated a twenty-four month inspection interval for all highway bridges located on public roads which is intended to detect problems before they become critical to structural performance.

This online engineering PDH course aims at identifying the key variables necessary in estimating the impact of regular washing of steel bridges on the paint and service life, recommending methods for recording data in order to most effectively estimate the benefits of bridge washing, and developing a framework to assess the impact of bridge washing on paint life.

Thirty years ago, when the environmental rules changed, the WSDOT stopped annual cleaning of steel truss bridges. Some cleaning was done after this time only to assist inspection crews or to determine what the cost would be to hand clean a steel truss bridge. WSDOT is investigating the feasibility of an annual steel truss bridge washing program. A pilot study was implemented in 2011 that will help to determine the benefits and environmental impacts of such a program.

This work builds on the pilot study to identify current bridge washing practices around the country and to select the measurements necessary to determine whether more regular washing has positive cost benefits. The research summarized in this course is a first step towards understanding and quantifying the benefits of a more regular bridge washing program on paint life and corrosion.

This online engineering PDH course provides basic information on procedures for selecting and applying in-place treatments to bridges to prevent or arrest degradation, and discusses different approaches for minimizing damage caused by fire.

Wooden bridges have a long history of use throughout the world, and like bridges made of other materials, the service life of wooden bridges can be enhanced through proper construction, inspection, and maintenance. Wooden bridges, whether historic covered bridges or current highway timber bridges, can be vulnerable to damage from biodeterioration, fire or biodegradation. Biodeterioration is minimized through design and construction practices, and in the case of modern timber bridges, through pressure treatment of the timbers with wood preservatives. However, over time, many bridges need maintenance in order to prevent degradation and to minimize any damage caused by fire.

In order to maintain wood bridges, different methods, procedures and treatments are used. These include; in-place treatments, surface-applied liquid treatments, paste surface treatments, internal treatments, and fire retardants, all of which are discussed in this course.

This online engineering PDH course provides an overview of the importance of safe rooms, as well as their design and construction process.

Every year, tornadoes, hurricanes, and other extreme windstorms cause injury, death, and property damage worth billions of dollars in the United States. Even so, more and more people build homes in tornado- and hurricane-prone areas, possibly putting themselves into the path of such storms. Having a safe room for your home or small business can help provide near-absolute protection for you and your family or employees from injury or death caused by the dangerous forces of extreme winds.

This 4 PDH online course is applicable to structural engineers, design professionals, homeowners and other technical personnel who are interested in learning more about designing and building safe rooms.

This online engineering PDH course describes typical loads for the design of reinforced concrete hydraulic structures (RCHS) and provides detailed information on design procedures along with examples of their application.

Reinforced concrete hydraulic structures have very long service lives and are subject to different types of loads, severe climatic conditions and sometimes to chemically contaminated atmosphere. To ensure a satisfactory long term service and to provide a safe, reliable and cost effective hydraulic structures, industry design and construction standards should be adopted.

Satisfactory long-term service requires that the saturated concrete be highly resistant to deterioration due to daily or seasonal weather cycles and tidal fluctuations at coastal sites. The often relatively massive members of RCHS must have adequate density and impermeability, and must sustain minimal cracking for control of leakage and for control of corrosion of the reinforcement. Most RCHS are lightly reinforced structures (reinforcement ratios less than 1%) composed of thick walls and slabs that have limited ductility compared to the fully ductile behavior of reinforced concrete buildings (in which reinforcement ratios are typically 1% or greater).

This online engineering PDH course provides guidelines on how to attach mechanical equipment to a building to minimize earthquake damage. It presents examples of anchoring and using special devices called seismic restraint devices. These devices include vibration isolation systems, cable or strut suspension systems, roof attachment systems and steel shapes.

This 5 PDH online course is applicable to structural and mechanical engineers, architects, contractors, building professionals, and other technical personnel dealing with the planning, design and installation of mechanical equipment.
