Seismic Forces in Ancillary Components Supported on Piers and Wharves

This paper presents a simple procedure to estimate seismic forces in ancillary components (secondary systems) supported on marine structures such as piers, wharves, and marine oil terminals (primary systems). Since many such marine structures can be idealized as single-degree-of-freedom (SDOF) systems, this study uses a simple linear-elastic model with two DOF, one representing the marine structure and the other representing the ancillary component. This study shows that acceleration at the base of the secondary system is approximately equal to spectral acceleration at the fundamental period of the primary system. It also proposes a formula, which is an improvement over current ASCE 7-10 recommendations, to estimate acceleration amplification in the secondary system due to its flexibility when mass and period ratios of the secondary and primary systems are known. The procedure in this paper is strictly applicable to marine structures for which primarily a single mode contributes to seismic response

Wellington after the Quake: The Challenge of Rebuilding Cities

The Wellington after the Quake conference sought to answer the questions faced by everyone in authority when cities commence recovery after a disaster: What happens next? What do I do now? I proposed the conference within the Earthquake Commission (EQC), both to provide background for our own disaster management planning and to assist public and private planning for disaster recovery. All other government agencies or departments, local authority councils, businesses, or large organisations that face severe damage in a disaster need to plan their recovery. In order to do so, they, like EQC, need a basis for their planning. The conference set out such a basis by identifying the problems sure to be faced and by indicating possible solutions based on world and New Zealand experience. Much of the planning in the public sector relating to disasters has focused on the response phase — people’s needs immediately after a disaster. So, too, with businesses, disaster recovery planning has focused on ways of getting the business up and running immediately, somewhere, somehow. Neither has dealt to any extent with the longer-term recovery from a disaster, including reconstruction of facilities, rebuilding of communities, and rebuilding of organisations. This conference brought together world and New Zealand authorities, with academic and technical expertise and with practical experience. The conference concentrated on Wellington, but by bringing to bear the best knowledge from around the world, its results are applicable to many cities around the world. The insights from this conference should be of value in every city that faces a risk of natural disaster. The conference was substantially supported by major sponsors, who are listed on page iii. The Earthquake Commission thanks the sponsors on its own behalf and on behalf of all those who attended the conference. Thanks are also due to the members of the organising committees for their invaluable help in making the conference a success

Urgent Recommendation Concerning "School Facility Improvement in Light of the Damage Caused by the Great East Japan Earthquake"

文部科学省において平成23年6月に「東日本大震災の被害を踏まえた学校施設の整備に関する検討会」（座長：長澤悟東洋大学理工学部教授）が設置され、この度の大震災における学校施設の被害状況等を踏まえ、学校施設の安全性や防災機能の確保など、特に重要な課題について検討が行われた。同年7月、本検討会においてこの緊急提言が取りまとめられた。提言は、■第１章　学校施設の安全性の確保　（１）学校施設の耐震化の促進　（２）非構造部材の耐震化　（３）津波対策　■第２章地域の拠点としての学校施設の機能の確保　（１）今回の震災を踏まえた学校施設の防災機能の向上について　（２）防災担当部局との連携　（３）地域の拠点としての学校を活用するための計画・設計　■第３章　電力供給力の減少等に対応するための学校施設の省エネルギー対策　の３章からの構成となっており、今回の震災の被害事例の他、具体的な対策事例なども紹介している
