Maine Structural 30 PDH Discount Package 3

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 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 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 an overview of the methods necessary for elevating residential structures for flood protection.

One of the most common of all retrofitting techniques is to raise an entire existing superstructure above the design Flood elevation (DFE). When properly elevated, the living area is placed above all but the most severe floods.

Elevating the house offers long term advantages over wet and dry floodproofing. Since cleanup after the flood is often much easier and limited to areas outside of the living area, elevating the house is often simpler and more cost effective than wet and dry floodproofing. The information in this course could also be useful in projects where elevating the house is necessary, regardless of the reason for elevating.

This 4 PDH online course is intended for engineers, architects, contractors and planners who are with the planning and implementation of elevating residential structures for flood protection.

This online engineering PDH course provides guidelines on how to attach Electrical 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.
