Topic: An Overview of Geosynthetic Composite Liner Systems

You are invited to a Technical Presentation and Initial Meeting of the Lower Scioto Valley Chapter of ASCE. The Chapter is part of the Central Ohio Section of ASCE.

The presentation will include an overview of the different components of composite containment liner systems for landfills and other projects.

Topic: Prefab Bridges & Structures

You are invited to a Technical Presentation and Initial Meeting of the Lower Scioto Valley Chapter of ASCE. The Chapter is part of the Central Ohio Section of ASCE.

The presentation will include the general use of precast bridges and structures, the selection and design process, and some of the latest innovations and applications of this technology.

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

Purpose and Background
This webinar concentrates on micropile foundations. Micropile foundations are often a technically sound and cost-effective foundation choice where a deep foundation solution is appropriate based on site conditions, applied loads and project schedule and performance requirements. The LRFD platform offers a rational framework for consideration of micropile foundation systems. The webinar will use the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge and Structures Specifications as a basis for the technical content. Applicable articles in Section 10.5 and 10.9 of AASHTO LRFD Specifications will be used as a basis of discussion.

The webinar will include discussion on the terminology and construction of micropiles, identification of limit states and resistance factors, axial compression and uplift resistance of a single micropile, estimation of grout-ground bond resistance and tip resistance, group efficiency factors for evaluation of axial resistance of micropiles in groups, buckling and lateral stability, lateral resistance of micropiles in groups, evaluation of settlement of micropile groups, concept of cased, uncased and plunge lengths, consideration of extreme event limits state such as scour and seismic events, corrosion and deterioration, and typical structural detailing and design. The webinar will assume that the participant has a basic working knowledge of design and construction of deep foundations.

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.

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.
