Calculation of heave of deep pier foundations

Design of pier and grade beam foundations in highly expansive soils is one of the most important and challenging aspects of geotechnical engineering. Existing design methods consider only uniform soil profiles, and piers with limited length to diameter ratios. These methods are restricted with regard to evaluation of more complex aspects of pier heave. A …more

Newcastle and Lake Macquarie Geology Tour

After receiving a strong response from the first notice of the AGS Newcastle-Lake Macquarie Geology Tour, the Newcastle Chapter Committee is pleased to announce that the excursion will go ahead as planned. Based on expenses and expected turnout, the costs to participants are as follows: $50 for AGS members, $100 for non-members, and $25 for …more

52nd Rankine Lecture (2012) Performance-Based Design In Geotechnical Engineering

Engineering design consists of a sequence of decisions which should satisfy the client’s objective performance requirements. This lecture will argue that an assessment of geotechnical performance must involve ground displacements, and that the traditional approach of specifying safety factors is potentially wasteful. In particular, the Limit State Design (LSD) approach adopted in the Eurocodes will …more

52nd Rankine Lecture: Performance-based design in geotechnical engineering

Performance-based design in geotechnical engineering by Professor Malcolm Bolton. Engineering design should consist of a sequence of decisions which should satisfy the client’s objective performance requirements. This lecture will argue that an assessment of geotechnical performance must involve ground displacements, and that the traditional approach of specifying safety factors is potentially wasteful. In particular, the …more

E.H. Davis Lecture

Predicting the bearing capacity of a foundation under combined vertical (V), horizontal (H) and moment (M) loads is a fundamental soil mechanics problem. Traditional solutions utilise ad-hoc adjustment factors to reduce the pure vertical bearing capacity in order to account for inclination, eccentricity, foundation shape and soil strength gradients. These procedures have their roots in …more

Advances in Piling Techniques and Design

The introduction of limit state analyses has required that all pile designs include calculations not only for geotechnical strength but also for serviceability. This has resulted in more rigorous calculations that in turn have forced the geotechnical profession to consider pile performance in a more thoroughly and has led to a better understanding of pile …more

Soil & Rock Logging Course – AS1726 Geotechnical Site Investigations

This one day course will aim to educate geotechnical engineers, geologists, geo‐technicians and other relevant professionals in logging and/or interpreting soil and rock logs in accordance with AS1726 – Geotechnical Site Investigations. This course is aimed at educating the profession and is particularly relevant to geotechnical and mining consultants, geotechnical contractors and laboratory geo‐technicians and …more

John Jaeger Award National Tour

Contrary to the popular view of geothermal energy, shallow geothermal systems make use of the ground at normal temperatures within a few tens of metres of the surface as a heat source in winter and a heat sink in summer to heat and cool buildings. A ground source heat pump or GSHP, in combination with …more

YGP Jack Morgan Award Presentation

The Jack Morgan Award is presented biennially to an outstanding Victorian geotechnical practitioner under the age of 35. This year, three applicants have been shortlisted to give 20 minute presentations on their chosen topic and an expert panel will judge each candidate on their contribution to geotechnics and understanding of geotechnical issues. The winner will …more

Use And Abuse Of Springs To Model Foundations

Springs are widely used in structural modelling packages to represent the stiffness response of foundations. This method is a significant improvement on models which assume the foundation is a rigid fixed or pinned support, and assigning a foundation stiffness is essential to enable structural models to better identify load re-distribution and deflection induced stresses in …more

Low level construction vibrations in residential structures

The first part of the presentation will examine the response of residential structures to low level vibrations by reviewing a comprehensive experimental program, which included a unique shaking-table study of a full-scale single-storey brick-veneer house subjected to 500+ vibrations, with Peak Particle Velocities (PPVs) ranging from 0.2 mm/s to about 400 mm/s (with interesting observations). …more
