Expert talk on Structural Dynamics and Extreme Loading

ExtremeLoading

Two leading experts in Australia on structural dynamics and extreme loading will give presentations on two topics in this field that are of interest to many practicing engineers.


When: 6:15pm, Monday, 4 July 2016

Where: Lecture Theatre C1 (Building 174, Room 407), 4th Floor, Engineering Building Block C, University of Melbourne, Parkville

Refreshments will provided from 5:45pm in Room C301 (Building 174), 3rd Floor, Engineering Block C


Our 2 topics for this presentation include:

1)    Dynamic Testing of Two Floors Featuring an Innovative Light Gauge Trussed Support Beam System

Presented by: Nicholas Haritos (Adjunct Professor, Swinburne University of Technology) 

Dynamic Steel Frames (DSF) steel fabricators (South Dandenong), winners of the 2016 ASI Steel Design Award in the Small Projects category have been collaborating with Swinburne University of Technology (SUT) on a number of features of their innovative Light Gauge Framing (LGF) system. 
DSF constructed two test floors featuring trussed support beams fabricated using their innovative LGF system. These test floors were then made available to Nicholas and project students from SUT to obtain their basic dynamic performance characteristics from in-situ testing.
This talk will describe the testing methodology and techniques used to derive these properties for the test two floors investigated, particularly relating results to vibration acceptability criteria for floors adopted in design codes.


2) Predicting Damage by Impact without the need of an impact test nor a computer software System

Presented by: Nelson Lam (Associate Professor and Reader, The University of Melbourne)

Impact action is not as well covered by codes of practice as other types of actions in structural engineering design such as seismic and wind actions. Guidance on this topic is also not adequately covered by the literature. Engineers often need to resort to undertaking costly field trials to demonstrate satisfactory performance of an installation (eg. a barrier) in a projected impact scenario. In fact, damage by impact can be predicted accurately on a test machine without the need of accelerating an impactor onto the target. No proprietary software is required either. Details on how this is accomplished will be presented.


Nicholas Haritos (FIEAust CPEng NER (Civil, Structural Leadership & Management)

Nick Haritos has been a long serving staff member at The University of Melbourne, where he currently holds the Honorary Position of Principal Fellow. Nick is also an Adjunct Professor at Swinburne University of Technology and a part-time charter assessor with Engineers Australia. He is a Director of Strucomp P/L who have developed and market the TechnoLab™ series of Mechanics & Dynamics teaching products. Nick is recognized internationally as an expert in the structural dynamics of land-based and offshore structures and in the use of dynamic testing techniques, such as experimental modal analysis in structural health monitoring and condition assessment applications, especially for road & foot bridges. He has more than 40 years of experience in academia, research and in specialist consulting. He has served on a number of technical committees including: IEAust (Structures Branch, Vic), SIA-Vic (AISC), SAA BD63 committee, the ISOPE (Hydrodynamics special interest group) amongst others. 

Nelson Lam (FIEAust MIStructE)

Nelson Lam is Reader in civil engineering at The University of Melbourne and has some 34 years’ experience in professional practice and research in earthquake and structural engineering. In the past 27 years, he has been working in the specialised fields of earthquake engineering and impact dynamics. He is member of the sub-committee that continuously develops the Australian Standard for Seismic Actions. Meanwhile, he has been appointed a member of the Earthquake Engineering Advisory Group to the London headquarters of the Institution of Structural Engineers. On the teaching side, he is recipient of the Engineers Australia Structural Branch – Victoria Division’s 2012 Award for Teaching Excellence and is co-ordinator of higher degree programs in civil/structural engineering at The University of Melbourne.

This event will start at 6:15pm in Room 407 (Lecture Theatre C1) on the 4th Floor of Engineering Building Block C, University of Melbourne, Parkville (Building 174, Grid L17 on this map.)

All IStructE Evening Technical Meetings are free to attend unless stated otherwise.
