Maritime Reporter and Engineering News
MARITIME REPORTER AND ENGINEERING NEWS SiEST COAST SHIPYARDS The Maritime Prepositioning lip, Pfc Eugene A. Obregon, Built By Notional Steel & Shipbuilding U.S. Navy Ship Overhaul Market JULY 16, 1985 - An Update - (SEE PAGE 4) INTRODUCING THE EPOCH MARK D SERIES A new era in product oil carrier design. Hitachi Zosen has developed the EPOCH MARK n series which has a unique structure not found on conventional ship designs. Revolutionary in concept, the MARKII incorporates a unidirectional girder system combined with a complete double hull structure. While a ship's hull is customarily designed with a grillage of longitudinal and transverse members for strength, this system uses only longitudinal members in a double hull to provide sufficient strength. This unidirectional girder system results in unprecedented structural simplicity and completely flush surfaced cargo tank interior. MARKII product oil carriers provide unrivaled advantages in performances over more conventional designs. The EPOCH MARK n series is available in 40, 60 and 80 thousands dwt designs. And has won the approval of leading classification societies (ABS, BV, LR, NK, NV). At present The Superior Performance of the EPOCH MARK n Series: many worldwide patents are under application. Conventional EPOCH MARK Hitachi Zosen is also expanding this new structural system for the development of combination cargo carriers such as PROBO or Tank configuration OBO carriers other than oil tankers.

Can you imagine a pleasurable public space, a street to enjoy walking, or a pleasant square inviting you to stop and sit for a while? I hope you have experi- enced this at least once in the urban space. Unfortunately, most metropolitan public spaces are far from being pleasant environments even providing inhospitable noisy places contrib- uting to a stressful and unhealthy city which reduces the quality of liveability. The following question might arise: Can urban decisions affect the soundscape? The answer is affirmative. Urban decisions can have an impact on the sound environment. Thus, sound is an essential factor that should be considered in any urban intervention. But how does one design urban spaces that provide a high quality sound environment? Due to the big gap between acoustics and urban planning, this question is difficult to answer. -

Global Analysis and Design of a Complex Slanted High-Rise Building with Tube Mega Frame
Global Analysis and design of a complex slanted High-Rise Building with Tube Mega Frame By Hamzah Al-Nassrawi and Grigorios Tsamis June 2017 TRITA-BKN. Master Thesis 520 , 2017 KTH School of ABE ISSN 1103-4297 SE-100 44 Stockholm ISRN KTH/BKN/EX--520 --SE SWEDEN © 2017 Royal Institute of Technology (KTH) Department of Civil and Architectural Engineering Division of Concrete Structures Abstract The need for tall buildings will increase in the future and new building techniques will emerge to full fill that need. Tyréns has developed a new structural system called Tube Mega Frame where the major loads are transferred to the ground through big columns located in the perimeter of the building. The new concept has the advantage of eliminating the core inside the heart of the building but furthermore gives countless possibilities and flexibility for a designer. The elimination of the central core, plus the multiformity the Tube Mega Frame, can result new building shapes if combined with new inventions like the Multi elevator Thussenkrupp developed. Multi is a new elevator system with the ability to move in all directions apart from vertically. In this thesis research of the possible combinations between TMF and Multi was conducted. The building shaped resulted is only one of the many possible outcomes which the mix of Multi and TMF can have. The building was constructed in a way so the TMF would be the main structural system, the building would have inclinations so the multi elevator would be the only elevator appropriate for the structure and the height would be significantly large. -

Response of Instrumented Buildings Under the 2016 Kaikoura¯ Earthquake
237 Bulletin of the New Zealand Society for Earthquake Engineering, Vol. 50, No. 2, June 2017 RESPONSE OF INSTRUMENTED BUILDINGS UNDER THE 2016 KAIKOURA¯ EARTHQUAKE Reagan Chandramohan1, Quincy Ma2, Liam M. Wotherspoon3, Brendon A. Bradley4, Mostafa Nayyerloo5, S. R. Uma6 and Max T. Stephens7 (Submitted March 2017; Reviewed April 2017; Accepted May 2017) ABSTRACT Six buildings in the Wellington region and the upper South Island, instrumented as part of the GeoNet Building Instrumentation Programme, recorded strong motion data during the 2016 Kaikoura¯ earthquake. The response of two of these buildings: the Bank of New Zealand (BNZ) Harbour Quays, and Ministry of Business, Innovation, and Employment (MBIE) buildings, are examined in detail. Their acceleration and displacement response was reconstructed from the recorded data, and their vibrational characteristics were examined by computing their frequency response functions. The location of the BNZ building in the CentrePort region on the Wellington waterfront, which experienced significant ground motion amplification in the 1–2 s period range due to site effects, resulted in the imposition of especially large demands on the building. The computed response of the two buildings are compared to the intensity of ground motions they experienced and the structural and nonstructural damage they suffered, in an effort to motivate the use of structural response data in the validation of performance objectives of building codes, structural modelling techniques, and fragility functions. Finally, the nature of challenges typically encountered in the interpretation of structural response data are highlighted.

Some NZ Earthquake Lessons and Better Building Construction
Some NZ Earthquake Lessons and Better Building Construction Gregory A. MacRae 1, G. Charles Clifton 2 and Michel Bruneau 3 1. Corresponding Author. Department of Civil and Natural Resources Engineering, University of Canterbury, Christchurch, New Zealand. Email: [email protected] 2. Department of Civil and Environmental Engineering, University of Auckland, Auckland, NZ Email: [email protected] 3. Professor, Department of Civil, Structural and Environmental Engineering University at Buffalo, Buffalo, New York, USA Email: [email protected] Abstract Over the past few years, the South Island of New Zealand has been subject to significant sequences of earthquake shaking. In particular, 2010-2011 events affected the city of Christchurch, resulting in widespread demolition of buildings. Also, the recent and continuing 11/2016 events caused severe damage in the countryside, in small towns, and moderate damage further afield. This paper summarizes general lessons associated with these events. It also describes “low damage construction” methods being used in NZ, and especially in the Christchurch rebuild, to limit the possibility of building demolition in future large seismic events. The buildings used in the Christchurch rebuild are generally supported by structural steel framing. These steel buildings include BRB systems, EBF systems with replaceable active links, rocking systems, base isolation using friction pendulum systems and/or lead-rubber dissipaters, RBS beams, lead extrusion dissipaters, yielding flexural dissipaters, and friction connections. Concerns about a number of currently used systems are discussed. It is shown that subjective quantitative tools, rather than purely probabilistic ones, may be more useful to engineers as they decide what structural system to use. -
Ships Built by the Charlestown Navy Yard
National Park Service U.S. Department of the Interior Boston National Historical Park Charlestown Navy Yard Ships Built By The Charlestown Navy Yard Prepared by Stephen P. Carlson Division of Cultural Resources Boston National Historical Park 2005 Author’s Note This booklet is a reproduction of an appendix to a historic resource study of the Charlestown Navy Yard, which in turn was a revision of a 1995 supplement to Boston National Historical Park’s information bulletin, The Broadside. That supplement was a condensation of a larger study of the same title prepared by the author in 1992. The information has been derived not only from standard published sources such as the Naval Historical Center’s multi-volume Dictionary of American Naval Fighting Ships but also from the Records of the Boston Naval Shipyard and the Charlestown Navy Yard Photograph Collection in the archives of Boston National Historical Park. All of the photographs in this publication are official U.S. Navy photographs from the collections of Boston National Historical Park or the Naval Historical Center. Front Cover: One of the most famous ships built by the Charlestown Navy Yard, the screw sloop USS Hartford (IX-13) is seen under full sail in Long Island Sound on August 10, 1905.
