Design of Foundations for Equipment Support

Date & Time: 
Fri, 01/23/2015 - 11:30am - 1:00pm
Location: 
E.L. Robinson Engineering, 1801 Watermark Drive, Suite 310, Columbus, OH 43215

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Purpose and Background
Design of foundations for equipment support is often required in industrial and process facilities, yet this topic is rarely, if ever, included in the engineering college curricula. Engineers are left to learn on the job – a process that often produces a variability of foundation designs for similar installations. In some cases the design is performed by the engineers who may or may not even have structural background. Yet whenever any component of an equipment foundation fails, the resulting strengthening and retrofit activities are often very expensive and intrusive into the equipment operations.

Deterioration and Repair of Concrete

Date & Time: 
Tue, 02/10/2015 - 11:30am - 1:00pm
Location: 
WD Partners, 7007 Discovery Blvd Dublin, OH 43017

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Purpose and Background
Concrete has been called durable but not eternal material. Despite its longevity, it eventually deteriorates and requires repair or replacement. This webinar focuses on repairing deteriorated concrete and restoring its structural capacity. (A related topic on strengthening concrete buildings in sound condition is addressed in a separate presentation.) The webinar provides a succinct overview of the issues involved in repair of concrete structures, with a focus on practical solutions useful for a design engineer.

Underpinning and Strengthening of Foundations

Date & Time: 
Thu, 01/08/2015 - 11:30am - 1:00pm
Location: 
WD Partners, 7007 Discovery Blvd Dublin, OH 43017

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Purpose and Background
Many renovation projects involve strengthening of foundations. Whenever an increase in gravity loading or a lateral load retrofit is proposed, foundation strengthening is likely to follow. Underpinning, the lowering or enlarging an existing foundation, is a basic technique of foundation strengthening. Underpinning of existing foundations is particularly common when new construction occurs nearby.

Recent advances in bicycle facility design guidance have led to increased demand from government agencies and the public to implement many of these innovative treatments. As more of these facilities are being implemented, users are recognizing the host of safety benefits and greater comfort level generated from the increased separation from automobile traffic and enhanced intersection treatments. Agencies throughout the country are using the design guidance recently issued within the National Association of City Transportation Officials Urban Bikeway Design Manual, in association with the guidance set forth in the established U.S. manuals such as the AASHTO Guide for the Development of Bicycle Facilities and MUTCD, to implement these facilities. The primary goals of this webinar are to familiarize transportation engineers/planners with the newest innovations in the bicycle facility design practice. The webinar will discuss recent developments in available design guidance and considerations when designing these facilities.

Creating Design Storms for Rainfall-Runoff Models

Date & Time: 
Mon, 06/16/2014 - 12:00pm - 1:00pm
Location: 
WD Partners, 7007 Discovery Blvd Dublin, OH 43017

*Open only to Central Ohio Section Members
*Seating is limited to the first 30 people
*Bring your own lunch

Purpose and Background
This webinar will cover the concepts related to creation of a design storm for use in hydraulic software packages, along with sources of rainfall data. Many projects require that a rainfall-runoff model be developed to determine the design flow for a storm sewer system, a detention pond, or some other hydraulic conveyance facility. This is typically completed using one of a variety of software packages, such as SWMM, HEC-HMS, or vendor software. These software packages require that rainfall information be input, usually in a time series; however, very little guidance is provided in the software packages on how to take the available rainfall information and create a time series that can be used in the software. Storm water design manuals usually include requirements such as designing for the 10-year, 24-hour event, or for the 25-year, 6-hour event, but provide no information on how to actually develop a design storm for these events. This webinar will cover the concepts related to creation of a design storm for use in hydraulic software packages, along with sources of rainfall data. The webinar will include examples of the different techniques so that attendees will be able to use them, along with appropriate rainfall data, to develop a design storm for any location.

Modern Roundabouts: The Geometric Aspects

Date & Time: 
Thu, 06/19/2014 - 12:00pm - 1:30pm
Location: 
Korda/Nemeth Engineering, Inc., 1650 Watermark Drive, Ste 200 Columbus, OH 43215

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Purpose and Background
This webinar will focus on the best practices for designing the geometric aspects of roundabouts to maximize the safety of all road users using guidance from the latest publications from FHWA and TRB. About 65% of all crashes in urban areas and 40% of all crashes in rural areas occur at or near intersections or driveways. Safety improvements at these locations have always been a priority and pose a challenge for most transportation agencies. Because crashes are typically complex events, a variety of mitigation measures have been tried with varying degrees of success, including the modern roundabout. This webinar will focus on the best practices for designing the geometric aspects of roundabouts to maximize the safety of all road users using guidance from the latest publications from FHWA and TRB. Case studies will be used to highlight problems that can result from roundabouts that are not designed in accordance with best practices.
