Seminar on Recent Advances in Analysis of Liquefaction


Wednesday, 23 November 2016

9.00 - 17.30, Room 401-311 and 401-312

Faculty of Engineering, 20 Symonds Street

Abstract

Liquefaction of sandy ground during earthquakes is a heavily nonlinear phenomenon. For example, dissipation of excess pore water pressure after liquefaction is a process that begins from the nearly zero effective stress state, i.e. nearly zero bulk modulus state. This type of a heavily nonlinear phenomenon poses a challenge in the analysis of liquefaction and associated phenomena. With the recent advances in analysis of liquefaction through effective stress analysis, controlling parameters have been identified on the rate of dissipation of excess pore water pressure, degree of settlements, and the effect of redistribution of excess pore water pressure under the effect of an impermeable thin layer at the ground surface. Details of these will be discussed at the seminar.

 

Learning outcomes

At the end of the seminar, you'll be able to understand:

  • the response of saturated sand to earthquake loading
  • the development of excess pore water pressure as a function of depth and time
  • the role of partial drainage and its effect on the dissipation of excess pore water pressure
  • the subsurface volumetric strain and the settlement of the ground surface in earthquakes
  • the role of structures in modifying free-field saturated sand response
  • the consequence of near-source earthquakes for the development of excess pore water pressure
  • the site-specific liquefaction assessment

2016 International Workshop on Seismic Performance of Soil-Foundation-Structure Systems

21-22 November 2016

The University of Auckland, Auckland, New Zealand

 

1

Purpose

In conventional design practice, earthquake-induced soil-foundation-structure interaction (SFSI) is seldom considered. If SFSI is considered, then usually linear soil behaviour is assumed. The influence of adjacent structures on the nonlinear seismic behaviour of a group of soil-foundation-structure systems is almost always ignored. Yet, the significant impact of nonlinear soil behaviour on the overall structural seismic performance prevails, particularly in regions with poor soil, as observed in almost all major earthquakes. The need for an urgent resolution of building damage, due to nonlinear soil-induced foundation failure, has been identified by the Royal Commission of Enquiry into the Canterbury sequence of earthquakes. Although it is known that the soil supporting one building and that supporting multiple buildings behave differently, the effect of multiple structure-foundation-soil systems has hardly been considered due to the complexity. An integrated consideration of even a single closely coupled soil-structure system is virtually unknown. These deficiencies will be addressed in this research. A clear understanding of the whole system dynamics will lead to more realistic and thus improved economic, resilient aseismic design of future cities.

Although past major earthquakes have caused extensive damage to life and property, they also serve as an opportunity to understand better the response of soil and structure foundations to large-scale earthquake shaking. With the wealth of information obtained in the aftermath, information-sharing and knowledge-exchange are vital in achieving better seismic design and rebuilding efforts in the coming years. The research has the objective of mitigating damage to structures located in regions with poor soil, by accounting for the complex interaction between seismic excitation and soil-footing-structure systems, set up during system response. This requires a good understanding of the technical point of view of the following disciplines, i.e. seismology, geotechnical engineering and structural engineering. This understanding will lead to new knowledge outside the sphere of any one discipline of engineering.

To ensure the future high resilience of civil infrastructure, the linkages between structural/geotechnical engineers, engineering seismologists and engineering geologists are essential. These crucial linkages have been identified by the Royal Commission on the Canterbury earthquakes and emphasized in the Royal Commission’s Recommendations. The main goal of this workshop is to develop greater collaboration and intensive dialogue by holding two discussion sessions, between distinguished world leaders in the geotechnical and structural fields. The intrinsically difficult issues associated with the seismic performance of soil-foundation-structure systems will be addressed.

Although the workshop will be open to the public, the participation of presenters will be by invitation only.

 

Instructions for Invited Participants

All invited participants are expected to prepare a paper describing their work. The template for the manuscript has been sent out and the deadline for submission of the final workshop manuscript is 15 October 2016.

After the workshop, we plan to publish an edited volume of proceedings, which will also include full accounts of the discussion sessions.

 

Public Attendance

The workshop will be open to the public. However, due to venue restrictions and for better and effective workshop discussions, the number of people from the public will be limited to those who register early (first come-first served basis). Details of the registration are indicated in the Registration page.

 

Venue

Please note that the workshop venue has been updated, as shown below.

The workshop will take place in Auckland at the University of Auckland, 38 Princes Street, 303-G02, Lecture Theatre PLT2. The university is conveniently located near the city centre and is within walking distance of the CBD.

2016 Some Japanese Achievements in Geotechnical Engineering

16 March 2016, 9.30am – 5.00pm

Venue         :    Room 902-402, Newmarket campus

Since the 1960s and before the Japanese geotechnical profession has made significant contributions to international understanding of soil mechanics, foundation engineering, and earthquake geotechnical engineering. Building on the presence of Professor Ikuo Towhata in Auckland on a Seelye Fellowship, we have invited two other prominent members of the Japanese geotechnical community to participate in a one-day seminar. In addition, some of the NZ geotechnical community who have benefited from Japanese experience will also speak.

The details of the event are below. The seminar is free (including lunch and tea/coffee), but the seating capacity is very limited (only 30 places) so you are asked to reply by email if you wish to attend.  Please hand this invitation on to others who might be interested.

Operational modal identification and applications to full-size bridges


24 April 2014

Research seminar presented by Professor Wei-Xin Ren, Hefei University, China.
 

Abstract

The operational vibration testing induced by an environmental excitation has the advantage of being inexpensive since no equipment is needed to excite the structure. The service state does not have to be interrupted. The real operating condition of the structure is incorporated in the analysis. In the case of output data-only dynamic testing, only response data are measured while actual loading conditions are unknown. A modal analysis procedure will therefore need to base itself on output-only data. Operational modal analysis using output-only measurements presents a challenge and requires the use of special identification techniques.

The objective of this seminar is to present the operational vibration testing and system identification of large-scale civil engineering structures. Two complementary modal analysis methods are implemented. They are rather simple Peak Picking (PP) method in frequency domain and more advanced Stochastic Subspace Identification (SSI) method in time domain. The real applications include: 

  • Operational vibration testing and baseline finite element modelling of a long-span cable-stayed bridge of 605 m over the Ming River at Fuzhou, China.
  • Seismic evaluation on a three continuous-span steel plate girder bridge over the Cumberland River on Interstate I-24 in western Kentucky, USA.
  • Finite element model updating of a concrete-filled steel tubular arch bridge of 90m in China.


Short biography

Dr Wei-Xin Ren is currently the Dean and Changjiang Distinguished Professor at Hefei University of Technology, China. He received his PhD in bridge engineering from Central South University, China in 1993 and followed two-year post-doctoral research in Tsinghua University, China. He was promoted to full professor in 1995 and was a visiting professor in Japan, Belgium, USA and Australia.

Recent advances in analysis of liquefaction


Professor Susumu Iai, Kyoto University, Japan

Host: New Zealand Society for Eathquake Engineering Inc.

Date: Monday 22 April 2013
 

Abstract


Liquefaction of sandy ground during earthquakes is a heavily nonlinear phenomenon. For example, dissipation of excess pore water pressure after liquefaction is a process that begins from the nearly zero effective stress state, ie, nearly zero bulk modulus state. This type of a heavily nonlinear phenomenon poses a challenge in the analysis of liquefaction and associated phenomena. With the recent advances in analysis of liquefaction through effective stress analysis, controlling parameters have been identified on the rate of dissipation of excess pore water pressure, degree of settlements, and the effect of redistribution of excess pore water pressure under the effect of an impermeable thin layer at the ground surface. Details of these were discussed at the seminar.

Simplified procedures for estimating earthquake induced slope displacements


Professor Jonathan Bray, University of California, Berkeley

Host: New Zealand Society for Earthquake Engineering Inc.

Date: Wednesday 17 April 2013

Abstract

Simplified procedures are commonly employed to estimate seismic displacements of earth and waste fills. The landmark work of Makdisi and Seed (1978) has been widely adopted in practice. Although this work is widely used, it has several significant limitations such as decoupling the sliding block analysis from the seismic response analysis, use of a limited number of recorded earthquake motions in its development, and the requirement to use the highly variable crest peak ground acceleration (PGA) as an input parameter. The Bray and Rathje (1998) method was an advancement in that it took advantage of the large number of ground motions recorded since the mid-70’s and used the less variable design rock PGA as the intensity input parameter. However, this method also has several limitations. An improved simplified procedure developed by Bray and Travasarou (2007) for estimating permanent displacements due to earthquake-induced shear deformations is presented.

The Bray and Travasarou (2007) method utilises a nonlinear fully coupled stick-slip deformable sliding block model to capture the dynamic performance of an earth dam, natural slope, compacted earth fill, or municipal solid-waste landfill. The primary source of uncertainty in assessing the likely performance of an earth/waste system during an earthquake is the input ground motion. Hence, a comprehensive database containing 688 recorded ground motions is used to compute seismic displacements. A seismic displacement model is developed that captures the primary influence of the system’s yield coefficient (ky), its initial fundamental period (Ts), and the ground motion’s spectral acceleration at a degraded period equal to 1.5Ts. The model separates the probability of “zero” displacement (i.e., < 1 cm) occurring from the distribution of “nonzero” displacement, so that very low values of calculated displacement do not bias the model. The seismic displacement model is validated through re-examination of 16 case histories of earth dam and solid-waste landfill performance. The proposed model can be implemented rigorously within a fully probabilistic framework or used deterministically to evaluate seismic displacement potential.
