Low-Density Concrete Properties Overview The use of low-density concrete provides several advantages with the primary, and most obvious, benefit being a 15 to 25 savings in weight without sacrificing the overall strength of a structure. However, the use of low-density concrete can result in a considerable impact to the structural design and cost of the structure. In this course, the student will review Engineer Circular (EC)  more...

Low-Density Concrete Construction Considerations Overview In general, concrete construction using low-density concrete is quite similar to using normal-density concrete. Constructability considerations related to mixing, placing, curing, pumping, and testing controls must be addressed in order to maximize the quality of concrete and avoid problems during construction. The use of low-density concrete provides several advantages with the  more...

Culvert Design This course presents terms related to culvert design. Based on certain design conditions, we will design a couple of culverts. We will design a circular concrete pipe culvert and a concrete box culvert. We will use nomographs for the design. We will also design rip rap for erosion control. The student must take a multiple choice quiz consisting of ten questions at the end of the course to earn  more...

Urban Hydrology This course provides an overview of hydrologic methods commonly used in urban drainage design. In this course, the student will review Chapter 3 of Hydraulic Engineering Circular 22, Urban Hydrologic Procedures. This chapter addresses the following subjects: Rainfall Determination of Peak Flow Rates Development of Design Hydrographs This course is relevant to municipal engineers, highway  more...

Design of Conduits Culverts and Pipes Overview The design procedure for conduits, culverts, and pipes vary due to life cycle considerations, material types used, loading types applied, and construction methods utilized. This course provides guidance on applying different types of loading such as (a) internal/external pressure, (b) vertical and horizontal pressures due to groundwater, surcharge water, and concentrated live loads,  more...

Introduction to Particle Accelerators Overview This course will provide the student with a general introduction to various types of particle accelerators, their construction, and their practical uses. This course is useful for anyone that may be involved with electrical, civil, or other type subprojects for particle accelerator laboratory construction, renovation, or maintenance projects, as well as engineers who work with low  more...

Electrical Conductors A conductor is a piece of metal used to conduct electricity, known colloquially as an electrical wire. Wires are very good conductors, which mean that they have very little resistance. In fact, their resistance is so small that often we consider it to be zero. (In other words, we often treat wires as perfect conductors). In the United States, conductors are measured by American wire gauge  more...
