Abstract: The Resilience by Design program adopted by Los Angeles to address earthquake vulnerabilities brought together the earth science, earthquake engineering and public policy professions and worked with hundreds of community organizations to get approval for sweeping seismic resilience legislation. The process elucidated the disconnect between what well-informed members of the community and local governments understand about the earthquake risk and the goals and objectives of mitigation measures like building codes, and what has been implemented in most communities. Since their inception, building codes have been based on a principle that safety is the only valid concern of government. If an owner chooses to build a building that is a total financial loss, that is his prerogative but he cannot kill someone in the process. A key factor is that building codes consider buildings in isolation with impacts only on their owners and tenants. But the reality of a major earthquake is that the failure of a building impacts the whole community through economic disruption, population decreases, and cascading failures of engineered and social systems. This talk will explore a conceptual framework for creating a building code that reflects the realities of earthquake losses and the social dynamics of shared economic decisions.

“Earthquake Risk Maps at FM Global”

FM Global insures commercial and industrial properties around the world and so requires a uniform worldwide assessment of earthquake risk for underwriting and engineering servicing decisions. We construct earthquake risk maps that show the return times of earthquake ground motions that can cause slight damage to URM low-rise buildings or slight-to-moderate damage to non-ductile concrete moment frame high-rise buildings. The steps to construct the risk maps are, first, perform a PSHA for a uniform soil, second, assign NEHRP site response categories and apply the NEHRP amplification factors, and third, compare the ground motions to the damage thresholds. The PSHA is performed on the OpenQuake software of the Global Earthquake Model. Site response categories are determined from the topographic slope method. The FM Global earthquake risk maps are different from building code maps in that the former account for soil conditions and show return times of spectral accelerations that initiate damage to weak buildings, whereas the latter present a ground motion parameter for a fixed return time without correcting for soil conditions.

Lecture Title: “Geotechnical-Earthquake Engineering Building Code Provisions and Impacts on Design” by Ehsan Kianirad, PhD of Haley and Aldrich

ABSTRACT: Seismic considerations of building codes have a significant impact on the design of structures. This presentation will shed light on important concepts and parameters that play a major role in seismic code provisions for buildings including the seismic hazard level, Maximum Considered Earthquake (MCE), site effects from soil and rock conditions, spectral acceleration coefficients, and seismic design category. Earthquake motions are represented by spectral acceleration coefficients provided in seismic hazard maps for the MCE. At a particular site, these motions are subject to site effects depending on soil and rock conditions. The spectral acceleration coefficients are combined with the site class to determine the design accelerations. Alternatively, site specific response analysis could be performed to obtain a design response spectrum for a particular site. Consequently, seismic design category (SDC) is determined from the design response spectrum and the structure’s desired level of performance. Applicable building design requirements are expressed as a function of the SDC in the building codes. A background on these issues will be provided, the process for determining the relevant parameters will be explained, and impacts on building designs will be discussed including regional considerations. Case histories will be used to illustrate key points.

Lecture Title: “Basis for Maximum Considered Earthquake Ground Motions in New England” by Nicolas Luco, Ph.D. of the United States Geological Survey (USGS)

ABSTRACT: The presentation will summarize the USGS computation of hazard curves for New England and explain the calculation of risk-targeted ground motions. A comparison will be made between Risk-Targeted Maximum Considered Earthquake (MCER) values in New England to their uniform-hazard Maximum Considered Earthquake (MCE) counterparts. Furthermore, the reasons for any changes in the New England region ground motion maps in the various editions of the IBC will be discussed. The MCER ground motion maps in the 2012 and 2015 editions of the International Building Code and MCE ground motion maps in previous editions are all based on the computations of the USGS National Seismic Hazard Mapping Project. For the MCE ground motions, the Building Seismic Safety Council interpolated the hazard curves at an exceedance probability that corresponds to 2% probability in 50 years. The interpolated ground motions are known as “uniform-hazard” ground motions, since the exceedance probability is geographically uniform. In contrast, for the MCER ground motions, all of the points on the computed hazard curves were used to develop maps that target a 1%-in-50-years collapse probability for new buildings. Since collapse probability is synonymous with collapse risk, the resulting ground motions are referred to as “risk-targeted.”

Lecture Title: “Potential Changes to Design Requirements for Earthquake Resistance and Its Impact on Design Practice in New England” by Dominic Kelly: Principal at Simpson Gumpertz & Heger

ABSTRACT: The Provisions Update Committee of the National Earthquake Hazards Reduction Program (NEHRP) is developing several proposals for change to seismic design provisions to be used in the U.S.  These proposals are in various stages of development, but all have the potential to lead to changes to the seismic design provisions of ASCE/SEI 7 Minimum Design Loads for Buildings and Other Structures.  This talk will describe several of the proposals that are being considered with a focus on those changes that likely will impact design practice in New England.   These proposals  include creation of design provisions that are applicable only to seismic design category (SDC) B buildings, revisions to the Simplified Seismic Design Procedure in ASCE/SEI 7, improved estimations of diaphragm force levels and ductility, a design approach applicable to buildings dominated by the response of a roof diaphragm, strength design for foundations, revised soil site factors, revised seismicity maps, and revisions to seismic design category criteria.
