Maryland Structural and Ethics 16 PDH Discount Package 3

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 information on protocols for the assessment and repair of bridge foundations.

This course is intended to provide guidance to bridge owners for preparing for and responding to bridge foundation failures. The word “failure” as used herein includes foundation movements and/or corrosion beyond the design norms for the structure that result in the need to close a bridge or portion thereof for any period of time. The movements and/or corrosion may or may not cause the bridge to be unsafe but are considered significant enough to close the bridge.

This course describes case histories of recent bridge foundation failures. It also provides guidance on preparing for foundation events by collecting records, establishing response teams and developing notification and communication protocols. Once an event has occurred, the course provides guidance for response including closing the bridge to traffic, notifying government and private parties, stabilizing the bridge site, investigative and monitoring techniques, repair and retrofit techniques. The course includes a check list intended to assist bridge in preparing for an incident and for developing a response once an incident has occurred.

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 presents the principles of engineering ethics that every engineer is expected to live by when practicing their profession.

Engineering ethics is (1) the study of moral issues and decisions confronting individuals and organizations involved in engineering and (2) the study of related questions about moral conduct, character, ideals and relationships of peoples and organizations involved in technological development (Martin and Schinzinger, Ethics in Engineering).

This course describes the fundamental legal concepts with which very engineer should be familiar. It also presents unique disciplinary case studies selected from across the nation, as well as hypothetical ethical challenges that demonstrate how difficult it can be to apply the code of ethics for engineers.
