A basic understanding of the underlying causes of concrete deficiencies is essential to performing meaningful evaluations which lead to the proper selection of the method or technique used to successfully repair concrete. Symptoms or observations of a deficiency must be differentiated from the actual cause of the deficiency, and it is imperative that causes and not symptoms be addressed in repairs. Deterioration of concrete is an extremely complex subject since, in most cases, the damage detected will be the result of more than one mechanism.
In this course, the student will review Chapter 3, Causes of Distress and Deterioration of Concrete from Engineer Manual (EM) 1110-2-2002, “Engineering and Design – Evaluation and Repair of Concrete Structures” published by the U.S. Army Corp of Engineers (issued 30 June 1995). This course is most relevant to engineers wishing to attain knowledge on the most common causes of problems in concrete. The course also provides a brief description of the basic mechanism of each common problem, a description of the typical symptoms that would be observed during a visual inspection, and suggests preventative methods or techniques to prevent further damage.
This course teaches the following specific knowledge and skills:
You will be able to immediately print a certificate of completion after passing a ten (10) question multiple-choice quiz. The quiz can be retaken unlimited times until a passing grade of 70% or better is earned. This course satisfies two (2) professional development hours (PDH) of continuing education.
This course describes the criteria for the design of concrete floor slabs on grade in buildings for heavy loads. Concrete floor slabs on grade are often subjected to heavy loads in buildings such as wall loads, stationary live loads and moving loads. The entire design procedure is based on a working stress concept. This course will provide the student with the criteria needed to design concrete floor slabs on grade subjected to heavy loads. Design examples are shown to aid in understanding the course material.
You will be able to immediately print a certificate of completion after passing a fifteen (15) question multiple-choice quiz. The quiz can be retaken unlimited times until a passing grade of 70% or better is earned. This course satisfies three (3) professional development hours (PDH) of continuing education.
Proper design, construction, and maintenance of hydraulic steel structures (HSS) is imperative for safe operation and reliable service over the structure’s lifetime. Engineers charged with the responsibility of maintaining these structures must be familiar with the basics of HSS design, as well as the intricacies of the structure’s abilities and limitations. This 4 hour interactive course prescribes guidance for (a) designing hydraulic steel structures (HSS) by load and resistance factor design (LRFD) and (b) fracture control. Allowable stress design (ASD) guidance is provided as an alternative design procedure or for those structure types where LRFD criteria have yet to be developed. Hydraulic steel structures are lock gates, tainter gates, tainter valves, bulkheads and stoplogs, vertical lift gates, components of hydroelectric and pumping plants, and miscellaneous structures such as lock wall accessories, local flood protection gates, and outlet works gates. HSS may be subject to submergence, wave action, hydraulic hammer, cavitation, impact, corrosion, and severe climatic conditions.
You will be able to immediately print a certificate of completion after passing a twenty (20) question multiple-choice quiz. The quiz can be retaken unlimited times until a passing grade of 70% or better is earned. This course satisfies four (4) professional development hours (PDH) of continuing education.
