PRESENTATION OVERVIEW:
Structural Engineers typically work on buildings, bridges and similar permanent infrastructure for which there are generally clear engineering requirements in codes. In contrast, temporary structures are handled inconsistently and lack clarity in the codes. This seminar will address engineering of structures that are used for temporary live events, such as concerts, public gatherings, sporting events, promotional events, pop-up commercial uses, and art installations. These structures can differ from conventional structures in their style of construction, use, methods of erection, monitoring opportunities, and relationship to the environment.

WEDNESDAY, APRIL 7 | 12:30 - 1:30 p.m. EDT: |
|
Changes to the Concrete Design Standard
Matthew Senecal, PE | Director of Engineering
American Concrete Institute
|
|
PRESENTATION OVERVIEW:
This new edition of Building Code Requirements for Structural Concrete is the first since the reorganized format was published in 2014 and includes new and updated code provisions. This presentation covers a few of the significant changes to this code including high-strength reinforcement, shear strength, development length, and shear lugs. A summary of other changes is provided at the end for reference.

|
THURSDAY, APRIL 8 | 11 a.m. - Noon EDT: |
|
Structural Roof Design for Rain and Ponding Loads
Aaron R. Lewis | Senior Principal
Simpson Gumpertz & Heger
|
|
PRESENTATION OVERVIEW:
This presentation will summarize the basis for determining the rain loads on an undeflected structure. We will also discuss the need for analyzing ponding loads due to the deflection of the roof structure. We will review pitfalls commonly encountered when coordinating the roof's loads with the architect and plumbing engineer and summarize how the code has evolved in response to roof structure collapses due to ponding rain loads. Attendees will also come away with what to expect in the next version of ASCE 7.

Proposed Changes to Snow Load Requirements
in ASCE/SEI 7-22
John F. Duntemann, PE, SE, Senior Principal
Wiss, Janney, Elstner Associates, Inc.
|
|
PRESENTATION OVERVIEW:
This presentation will provide a preview of proposed changes to the snow load requirements in ASCE/SEI 7-22. Specific topics will include the introduction of new ground snow load (GSL) maps and revisions to the snow drift provisions due to “winter wind”. The proposed revisions to the GSL maps are the first substantive change to the ground snow loads in ASCE/SEI 7 since the 1995 edition of the Standard and based upon reliability-targeted values.
