2017 SEAONC Summer Seminar: Examples from the Latest SEAOC Structural Seismic Design Manual

2017 SEAONC Summer Seminar: Examples from the Latest SEAOC Structural Seismic Design Manual


When: Thursdays, June 8 and 15, 2017

Time: 6:00 p.m. – 9:00 p.m

 Where: PG&E Auditorium, San Francisco

 

The 2017 SEAONC Summer Seminar will feature in-depth design examples from Volumes 1 – 3 of the newly revised 2015 SEAOC Structural Seismic Design Manuals (SSDM). The seminar will begin with a presentation on seismic analysis and design principles from Volume 1 of the SSDM, and follow with in-depth example problems from Volumes 2 and 3 including concrete special moment frames, concrete pile foundations, concrete shear walls and coupling beams, steel light-gage, and wood light-frame building systems. Through this seminar, presented by the manual’s contributing authors, attendees will gain a better understanding of seismic design for various building systems and structural elements.
 
 
Evening 1:
Seismic Analysis and Design Principles – SEAOC SSDM Volume 1
Speaker: Geoff Bomba, Forell/Elsesser Engineers
 

2015 SSDM Volume 1 presents 58 short examples covering most of the key code provisions from ASCE 7 Chapters 11, 12, 13 and 15. These examples have been updated and revised to reflect applicable changes to codes and standards, to provide additional clarification and commentary for the more complex or nuanced provisions, and to incorporate input from the SEAOC Seismology Committee and other practicing engineers regarding latest interpretations and recommended practices. This presentation on Seismic Design Basics will include examples addressing the equivalent lateral force procedure base shear, response spectrum analysis, diaphragm design, and structural irregularities.
 

 
Concrete Pile Foundation Design – SEAOC SSDM Volume 3, Example 5
Speaker: Stephen Harris, Simpson Gumpertz & Heger


The presentation includes a review of Example 5 in Volume 3 of the SEAOC Design Manual, which pertains to the design of a cast-in-place concrete pile foundation.  The foundation addressed in the example is a post-tensioned concrete parking garage.  However, the pile design methodology is applicable to any building.  The presentation includes recommendations for coordination with the geotechnical engineer, determination of the most cost-effective geotechnical pile capacity for the project, determining the number of piles at each location, geotechnical and structural design of the piles to resist vertical and lateral loading, distribution of base shear, review of applicable Code requirements and recommendations for detailing.
 

 
Reinforced Concrete Special Moment Frame – SEAOC SSDM Volume 3, Example 3
Speaker: Jon Kiland, IDA Structural Engineers
 

Design example 3 is for a reinforced concrete special moment frame building in the SEAOC Structural / Seismic Design Manual, Volume 3, 2015 Edition, Examples for Concrete Buildings.  It is written in accordance with the 2015 International Building Code, ASCE 7-10 and ACI-318-14.  In 2014, ACI 318-14 was reorganized and the design example has been updated to the new ACI 318-14 provisions. The example building is seven stories with concrete floors and perimeter special moment frames located in a high seismic area.  Mr. Kiland will discuss details and highlights of the design example, the new organization of ACI 318-14, and the important aspects and considerations for design and detailing of reinforced concrete special moment frames.  He will conclude with examples of past performance in strong earthquakes.
 


Evening 2:
Reinforced Concrete Shear Walls and Coupling Beams – SEAOC SSDM Volume 3, Examples 1 and 2
Speaker: Karl Telleen, Maffei Structural Engineers
 

SEAOC Seismic Design Manual Volume III Example 1 covers seismic design of a solid (cantilever) concrete wall, and Example 2 is a concrete wall with openings and coupling beams. Both examples will be presented in parallel, focusing on key concepts including: desired behavior of concrete walls, design for flexure, bar cut-offs and lap splices, design for shear, effect of gravity framing, detailing of wall boundaries, detailing of coupling beams, and wall stiffness. The presentation will draw on observations and lessons learned from past earthquakes, in addition to code requirements and recommendations from research.
 
 
Three-Story Cold-Formed Steel Light Frame Building – SEAOC SSDM Volume 2
Speaker: Jeff Ellis, Simpson Strong-Tie
 

Many of the questions regarding cold-formed steel framed seismic force-resisting systems deal with which floor framing system should be used, overturning restraint options and their design and detailing, wall stud bracing design and detailing, the use of the overstrength factor (Wo), and anchorage of the overturning restraint system to concrete. Therefore, this presentation focuses on these aspects of design as covered in the SSDM design example.
 
 
Four-Story Wood Light Frame Building – SEAOC SSDM Volume 2
Speaker: Doug Thompson, STB Structural Engineers
 

The presentation will be based upon the design example “Four-story Wood Light-frame Structure” in Volume 2 of the SSDM series. Presentation will talk about rigid vs flexible diaphragms and potential problems with torsion in these types of buildings. Presentation will include the design and detailing for a multi-story wood framed shear walls using the continuous tie down system including boundary element and tension rod design. The presentation will also include how to calculate wood frame shear wall deflections. There will be a brief discussion on the design and detailing of wood framed trusses and the use of collector trusses. The presentation will conclude with a side by side comparison of force-transfer-around-openings (FTAO) using both the SEAOC/Thompson Method and the Diekmann Method.
