Short Courses

All short courses take place on Sunday, June 10.

**Please note: all short courses require a separate fee, which can be paid when you register.

Short Course 1: Principles and Applications of Seismic Soil-Structure Interaction

1:00 – 5:00 p.m.

In this short course, the instructor will explain the physical principles that control soil-structure interaction under seismic loading conditions.

Issues addressed include:

  • mechanisms responsible for changes in ground motions from free-field to foundation conditions
  • factors affecting the stiffness and damping of foundation-soil systems
  • the response of structural systems founded on non-rigidly supported foundations

This will provide the attendee with an understanding of why soil-structure effects occur and under what conditions they are likely to be significant. Models used to capture kinematic and inertial soil-structure interaction effects will be discussed, emphasizing their physical basis and limitations, with example applications to illustrate the steps involved in using the models and their effects on structural response. How these procedures are incorporated into design codes and standards will be described.

A specific type of soil-structure interaction that is widely encountered is the development of seismic earth pressures on earth retaining structures. Drawing upon the principles developed in earlier parts of the course, the instructor will explain the mechanisms that give rise to seismic earth pressures, methods of analysis that capture these mechanisms, and how such methods are being adapted for use in building code applications.

Instructor: Jonathan P. Stewart, Ph.D., P.E., Professor and Chair of Civil & Environmental Engineering, UCLA

Short Course 2: In-situ Seismic Testing: What Engineers Should Know About Quality and Uncertainty

8:00 a.m. – 5:00 p.m.

Engineers frequently require parameters obtained from in-situ seismic testing for use in modeling and design of civil infrastructure. While in-situ measurements of shear wave velocity (Vs) are most commonly required, measurements of compression wave velocity (Vp) and estimates of fundamental site period (T0) obtained from horizontal-to-vertical (H/V) spectral ratio measurements are increasingly in demand, particularly for geotechnical earthquake engineering applications such as site response and liquefaction analyses.

As with all products sold on the open market, the quality of in-situ seismic testing varies substantially. Furthermore, it is extremely uncommon for even the best contractors/firms to provide realistic estimates of uncertainty with their measurements. Thus, many engineers are left to use results of unknown quality with assumed values of uncertainty for complex analyses. This course will provide guidance to engineers and other end-users about how to judge the quality of results obtained from in-situ seismic tests. It will also present information that will help engineers encourage realistic quantification of uncertainty.

While participants will most certainly gain valuable insights into properly conducting in-situ seismic tests and processing data, the course is aimed more at training engineers to be expert users of seismic data than to be expert providers.

The course will cover the following topics:

  • Invasive/borehole methods (e.g., SCPT, downhole, crosshole, PS suspension logging)
  • Non-invasive/surface methods (e.g., refraction, SASW, MASW, ReMiTM, MAM)
  • H/V spectral ratio noise measurements for estimating T0 and seismic site classification
  • Accounting for epistemic uncertainty and aleatory variability of Vs in seismic site response
  • Combined CPT-Vs-Vp methods for evaluating liquefaction triggering

Short Course 3: Numerical Modeling for Geotechnical Earthquake Engineering Applications

8:00 a.m. – 5:00 p.m.

In this short course, the instructors will discuss the principles of nonlinear dynamic analyses, constitutive laws for soils and procedures used to perform numerical modeling for geotechnical earthquake engineering applications. They will:

  • illustrate the use of various constitutive laws (e.g., HSS Small, UBCSand, PM4Sand)
  • discuss material parameter determination and calibration
  • evaluate the capabilities and limitations of these models
  • present recommended practices for deformation analyses using finite element and finite difference approaches

The course will provide a level of familiarity with nonlinear dynamic analyses, nonlinear constitutive soil models, soil liquefaction, and the use of computer programs such as FLAC and/or PLAXIS.

The morning session will focus on basic principles and simple constitutive models and procedures to simulate nonlinear ground response. Topics include:

  • general concepts and classification of dynamic problems
  • effect of boundary conditions
  • effect of soil stiffness and damping on ground and structural response and their influence on soil structure interaction
  • determination of small strain stiffness and shear strain dependent shear modulus and damping for sands, clays and intermediate soils, stiffness and strength degradation

The lectures will then focus on the use of more advanced models and will include hands-on calibration exercises using single element simulations.

The afternoon will focus on modeling liquefaction problems using the constitutive model PM4Sand. Topics include:

  • theoretical background of PM4Sand (formulation and implementation)
  • calibration procedures for engineering applications (single element simulations of various loading paths; capabilities and limitations)
  • hands-on calibration exercises for an engineering application
  • validation example focused on recommended practices for evaluating and documenting results of nonlinear dynamic analyses
  • general discussion of best practices and modeling details

Instructors: Juan M. Pestana, Sc.D., P.E., Senior Principal Geotechnical Engineer, Geosyntec Consultants, and Katerina Ziotopoulou, Ph.D., A.M.ASCE, Assistant Professor, University of California, Davis
