Members of the Earthquake Engineering Field Investigation Team (EEFIT) recent mission to Japan’s Tohoku region report their findings from studying the affected areas in Iwate and Miyagi prefectures. Investigations included:

• Damage surveys due to ground shaking in relation to recorded ground motion, tsunami damage to buildings and coastal structures across a 300 km coastline (from Miyako to Yamamoto)
• Interviews and meetings with various academics and city officials in the tsunami affected region
• Investigations about the management of the evacuation before the arrival of the tsunami and the crisis management following the disaster and the recovery plans
• Investigations into the effects of the earthquake on the energy sector.

Our Institution was founded for members to share knowledge and learn from each other: that need remains today. Over the last half century there has been an explosion of structural information, more complex codes, phenomenal analytical power and an ability to understand the forces nature imposes on structures to a degree hereto unimaginable. But all that information has to be collated and disseminated to successive generations. What are the challenges and how do we do it?

Members of the Earthquake Engineering Field Investigation Team (EEFIT) recent mission to Christchurch present their observations and findings. Some of the interesting features of this earthquake are:

• the high intensity ground shaking
• wide scale liquefaction
• damage to masonry structures
• damage to modern engineered buildings
• landslides
• and the disaster response of the New Zealand people and authorities.

Engineers are usually reluctant to engage directly in aesthetics questions related to their work. The quest for beauty is nevertheless extremely present in engineering design. Using examples from the past as well as from the present, the lecture will discuss the various forms taken by such a quest, from the economy of material to structural expressionism.

In his address Roger will be focusing on the theme of 'Adding Value'. He will consider this topic under two specific strands:

• Structural engineering adding value as a profession
• The Institution adding value to the benefit of its members

Additionally Roger will consider the growing opportunities of structural engineers to provide value adding expertise beyond their traditional core activities.

This talk will not be a beauty parade of past personal glories. Instead, in the light of today’s designerly challenges, Chris Wise will use the significance of the Milne Medal lecture to propose how the structural engineering design community might adapt its culture to take some simple practical actions. In the global context of our work, he will compare and contrast progress in structural engineering with the rapid pace of technological advance in other fields, and suggest how the good structural designer should take a lead in reducing resource-depletion and increasing sustainability. All of which would be no good if it saddled the world with what one eminent civil engineer has called "lumpy objects", so an intrinsic part of the talk will be an investigation of how the search for engineering sustainability can lead to a high engineering aesthetic.

Heron Tower is a 47 storey above ground, three levels below ground, office building in the City of London. Located on Bishopsgate near Liverpool Street train station it accompanies Swiss Re and Tower 42 as landmarks on the London city horizon. It is part of a collection of new generation tall buildings that will change the appearance of the City in coming years and will be completed in February 2011.

The presentation will focus on the development of the structural design that emerged from the challenges specific to the site combined with the aspirations of the client and architect. The strategy assembled for the structural engineering, and the strong reliance on careful engineering logic will be discussed.

Each aspect will be explained in such a manner as to be understood by all attendees, irrespective of age, education or discipline. Structural aspects will be discussed and explained in physical and not too much mathematical terms. Calculators and mathematical knowledge can be left at home.

Relevance to the 21st Century and reason for presentation:
There are many buildings with roofs of this type in the UK and abroad which are nearing the end of their design life, such that they may require refurbishment or demolition. They were patented in the UK 1957, ceased to be manufactured in 1984.

As there are few people alive with comprehensive knowledge of this form of construction and little, if any, archived information, this presentation will prove invaluable to those appointed to advise about such roofs in the future.

Members of the Earthquake Engineering Field Investigation Team (EEFIT) recent mission to Chile will present their findings focussing on:

• the logistical lessons learned when organising a mission
• the good performance of many reinforced concrete shear wall buildings
• the failure of a number of relatively new bridges
• the impact of the tsunami on coastal population and infrastructure
• the impressive way that the Chilean people and their government has reacted following the event.

Keith Clarke is chief executive of Atkins, the largest engineering consultancy in the UK and one of the world’s largest design companies. A Chartered Architect with more than 30 years’ experience in construction and engineering, he is also currently serving as chairman of the UK Construction Industry Council (CIC), having previously chaired its Health and Safety Committee.

Keith is at the forefront of encouraging the built environment sector to embrace Carbon Critical Design in response to the urgent challenge of climate change. He believes carbon must become a core decision making factor in the way we plan, design and procure capital projects.
