PRESENTATION TOPICS & ABSTRACTS:
2015 IBC SEAOC Structural/Seismic Design Manual - Irregularities & Discontinuous Elements -by Kelly Cobeen, S.E.
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.
2015 IBC SEAOC Structural/Seismic Design Manual - Wood Frame Design Examples - by Doug Thompson, S.E., S.E.C.B.
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.
2015 IBC SEAOC Structural/Seismic Design Manual - Cold-Formed Steel Design Examples - by Jeff Ellis, P.E., S.E., S.E.C.B.
Many of the questions regarding cold-formed steel framed seismic force-resisting systems regard the 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, 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.
Introduction to Santa Monica Ordinance & Basic Requirements - by Daniel Zepeda, S.E. & Jeff Roi, S.E.
The City of Santa Monica has been an active proponent of seismic safety since the 1994 Northridge Earthquake. Since then they have had active ordinances for vulnerable buildings, however they have been mainly been triggered by major renovations. In a wide spread effort to improve the safety of Santa Monica, the City has recently passed mandatory seismic ordinances for URM, concrete tilt-up, wood soft-story, non-ductile concrete, and steel moment frame buildings. Our presentation will provide a brief overview of the history of these ordinances in Santa Monica and discuss the policy, prioritization, timeframes, technical guidelines, and building target performance.
Seismic Retrofit of Unreinforced Masonry Structures Using Fiber Reinforced Polymers - by Pedram Zohrevand, PhD, P.E. & Saeed Fathali, Ph.D., P.E., LEED AP
This presentation will review:
* Mechanical Properties of FRP Composites
* Most Common FRP Products and Retrofit Techniques
* FRP Design Process (Design Guidelines and Standards)
* FRP Installation, Construction Specifications, and Inspection
* Feasibility of FRP Retrofit techniques for Unreinfoced Masonry Buildings and Associated Costs
Pre-Northridge Steel Moment Frames - History & Rehabilitation Techniques - by Jonathan Buckalew, S.E. & Russell McLellan, M.S.
This presentation will discuss the performance of Steel Moment Frames constructed to building codes prior to the 1994 UBC Emergency Provisions. Key deficiencies of these structures will be discussed as well as common seismic rehabilitation techniques.
