Parking Structures - WEBINAR WEDNESDAYS
Our Free 2021/2022 Webinar Wednesday Program will focus on the evaluation, repair and protection of parking structures. Each webinar will be 1 hour in length. Professional development certificates approved by the National Council of Structural Engineer Associations (NCSEA) are available for all participants.

At this time, there are no upcoming Parking Structures events.
Description: Precast double tee beams are widely used in parking and other structures where long spans are required or where the structure must carry heavy loads. Double tees are manufactured under controlled environments, which result in consistent high-quality concrete. In addition, double tees can be rapidly installed making them a go-to for many engineers who are schedule conscious. However, the flange-to-flange shear connectors in double tee construction are susceptible to premature failure from fatigue and corrosion causing costly interventions. This webinar will explore a simple innovative technology aimed at the repair of failed flange-to-flange connectors.
Description: Parking structure use requirements and even their capacity to carry design loads can change over time. Building standards can change so the structure must be made compliant, loads can increase and the environmental exposure conditions can degrade a structure’s capacity. There are many methods of structural strengthening available today and one of the most used and economical is carbon fiber strengthening. This webinar will compare the various forms and applications of carbon fiber strengthening.
Description: Unbonded post-tensioning has been employed by engineers in the design and construction of buildings and parking structures for decades. Though the technology has evolved and improved over the years, early generations of the technology were highly susceptible to moisture infiltration and corrosion of the high tensile steel strands. This pernicious risk often flies under the radar until a strand violently erupts from the concrete. This webinar will discuss the methods of unbonded post-tensioning evaluation, corrosion mitigation and repair.
Description: The “Halo Effect” or “Patch Accelerated Corrosion” is a long known and well documented phenomenon whereby performing a quality concrete repair actually accelerates corrosion in the parent concrete around the repair. Embedded galvanic anodes can be used to mitigate the “Halo effect” as well as proactively prevent corrosion in “hot spot” areas before there is even a need for concrete repair. This webinar will review corrosion cells and how they initiate, the “Halo Effect” and how embedded galvanic anodes provide protection to concrete parking structure elements.
Description: Impressed current cathodic protection (ICCP) systems have successfully been used to protect embedded reinforcing steel from corrosion in concrete structures since the early 1970’s. Since then, the field has evolved with respect to new innovations in material science and practitioners have learned many lessons as it relates to the design, installation, and maintenance of these systems. This webinar will discuss the history of ICCP systems, modern approaches to design and current applications on parking structures.
Description: The majority world’s existing parking structures were built decades ago and through environmental exposure, age and wear are in dire need of rehabilitation. There are many repair strategies and protection systems available today and knowing how to perform long lasting, durable concrete repairs is critical to extending a parking structure’s service life. This webinar will review the steps involved in performing a quality concrete repair and explore the various protection systems to ensure that repair lasts the test of time.
Description: Corrosion of reinforcing steel is the #1 cause of concrete failure for parking structures. Before asking how we can prevent corrosion, we must understand the underlying cause and quantify the severity and extent of corrosion risk. There are many destructive and non-destructive test methods that are effective in assessing corrosion risk. No one method will provide the complete picture, but in combination these tools can provide a holistic view of the structure’s health. This webinar will compare and contrast the various methods available today.
