SPRING CONTINUING EDUCATION PROGRAMS

Precast Concrete Structural Design Seminar

April 28, 2011 - Boston

PCI Handbook

It’s not to late to register for the PCI Structural Design Seminar being held at the Westin Hotel in Waltham MA on April 28. This course will guide the attendee through the design of a 3-story, integrated precast office building using the PCI Design Handbook (7th Edition) as a reference. Review erection drawings and learn how collaborations with the producer of structural concrete products (precaster or specialty engineer) can streamline the relay of technical information to the production floor to ensure a final product that strictly adheres to specification and design. A detailed step-by-step connection design will also be covered in the presentation.

Highlights and learning objectives are:

  • Overview schematic building design
  • Estimate product sizes using load tables
  • Preliminary analysis of bearing haunch steel
  • Discuss lateral load options
  • Review structural specifications
  • Design responsibility
  • Engineer if record check list
  • Review precast erection drawings and calculation submittals
  • Connection design
  • PCI design handbook overview / changes from 6th Edition / 7th Edition

Continuing Education Credits: Attendees will earn 7.5 Professional Development Hours (PDH) or 7.5 HSW-Learning Units (LU). A certificate will be provided at the conclusion of the seminar and attendance data will be submitted to the National Council of Examiners of Engineers and Surveyors, for which PCI is a Registered Continuing Education Provider. Attendance data will be submitted to AIA for any AIA member.

Seminar Fees:
$295 - This fee includes a copy of the PCI Design Handbook 7th Edition to use as a reference for years to come, a CD of the handbook, seminar notes, breaks and lunch. Participants who are not already PCI members will also receive a FREE one-year individual PCI membership.

$225 - includes all of the materials above EXCEPT the PCI Design Handbook text. You will receive a CD-only of the handbook. (Bring your laptop to class to facilitate your learning experience.)

This highly interactive course is a “don’t miss!” opportunity.

Providing Safety with FEMA 361: Community Storm Shelters

Presenter: Dave Robertson, Jr., LEED AP

April 28, 2011

Fema361 This presentation examines FEMA 361 design for Community Safe Rooms. Learn about the properties of a tornadic event, common locations and applications for safe rooms, and FEMA 361 guidelines. Delve into the details of using precast concrete according to FEMA 361 guidelines for safe room design, including discussion of how to maximize the application of the building system to meet the needs of the FEMA grant process. During the presentation, there will be discussion concerning aesthetics, thermal properties, and detail that is unique to FEMA 361 design.

Parking Structures: Historical Development and Emerging Trends

Presenter: Tom Broch

June 2, 2011

Parking This webinar focuses on the history and development of the parking structure. Beginning with its origins as an urban amenity, primarily for the wealthy, this presentation traces the trajectory of the continuing evolution of the parking garage up to the present. The session will discuss the design goals of parking structures and investigate how those have evolved over time, as well as review current and emerging trends. Additionally, attendees will learn what can make a parking structure qualify as a "green building."

NEXT BEAM RESEARCH

Next Beam Field Monitoring of an Integral Prestressed Concrete Bridge using NEXT Beams

NEXT Beam Research Project is underway at the University of Massachusetts in Amherst MA. under the direction of Professor Sergio Brena.  The research is being sponsored by the Massachusetts Department of Transportation, PCI National, PCI Northeast; New Hampshire Department of Transportation and Central Atlantic Bridge Association.

The main goal of this research project is to provide an understanding of field performance of NEXT beam bridges through live-load field testing and long-term monitoring. Field testing will be supplemented with detailed finite element modeling of a prototype bridge to evaluate live load distribution factors for this type of superstructure.

A detailed Finite Element model of the Brimfield MA bridge including NEXT beams, deck (shell elements), abutments (thick shells) and H-piles with soil springs will be developed. The model is being loaded with HS20 trucks to determine live load distribution factors for that bridge. Umass is in the process of conducting parametric studies of the FEM model to include variations in skew angle, bridge length, and soil properties to assess distribution factors for a wider number of bridges rather than just the Brimfield bridge.

To date, parametric studies using FEM models of NEXT beam bridges are being conducted. The parameters being investigated include bridge span, end support conditions, and skew angle. Their effects on AASHTO Live Load distribution factors are being examined. A comparison of FEM determined LLDFs and AASHTO distribution factor equations in being conducted as well. Review of the instrumentation submittal for the Brimfield Bridge was conducted. Fabrication of the NEXT beams William E. Dailey Precast, LLC has begun and the project is scheduled for construction this Summer.
