NSAI – Eurocode Review

nsai

FAO all members, the NSAI would like to bring the following to your attention;

The European technical committee dealing with Structural Eurocodes, CEN/TC 250 has started a systematic review of the suite of Eurocodes.  The review will be phased.  The first phase includes the review of 31 out of the 58 parts of the Eurocodes.  The 31 parts available for comment are listed on the NSAI website, accessible via the link below.  This is an opportunity for the Irish engineering community to identify any modifications that are required to improve the suite of Eurocodes.

Please follow the link to comment. 

Microsoft EPDC/5 (No. 17 Jul-04)

In 2000, Microsoft celebrated fifteen years of business in Ireland. In the same year, Microsoft sited a three-acre greenfield site at the IDA South County Business Park, Leopardstown, Co Dublin for its new European Product Development Centre, EPDC5. This site is adjacent to the existing EPDC/2 product development facility, which opened December 1995.

The new €42m EPDC/5 facility consists of 11,488 square meters of floor area together with 322 car-parking spaces. Read the rest of this entry »

Army Corps of Engineers (No. 17 Jul-04)

The Irish Army Corps of Engineers, in addition to providing military engineering support to Defence Force units, has responsibility for the maintenance and upgrading of all military posts, including Air Corps and Naval facilities. To facilitate this role the Corps establishment includes for architects, engineers of various disciplines, a quantity surveying section, technicians and drawing office staff. A major programme to upgrade Defence Forces building infrastructure and services has been underway for a number of years. Projects are either designed in-house or using outside consultants, depending on the resources available at any given time. Read the rest of this entry »

Introduction of the Eurocodes (No. 17 Jul-04)

In the next seven or eight months the Eurocodes will be published with National Application Documents; they will be in use as alternative codes of practice for engineering design. This transition period will show designers who take the trouble to read the documents that there are savings to be made in the structures designed with theses new rules and in some cases they will highlight shortcomings in or current methods of design.

Study Confirms Steel as Best Option (No. 17 Jul-04)

A new study comparing steel and concrete building costs reveals the size of the competitive gap that has opened up between steel and concrete. The study – “Comparative Structure Cost of Modern Commercial Buildings (2004 Revision)” – confirms that despite price rises, the frame and floor costs for multi storey commercial buildings show a 30% cost advantage for structural steelwork based solutions compared to the reinforced concrete based alternatives.

Cost Saving in Bridge Assessment by Application of Advanced Methods (No. 16 Nov-03)

Many countries are experiencing problems in management of bridge stocks due to the increasing demand on load carrying capacity combined with low budgets for rehabilitation and strengthening of older bridges.

Benefits are obtained from the difference between a general approach and a more thorough individual approach. The general approach for safety evaluation of existing bridges is based on codes and regulations for evaluation of bridges. The fact that codes generalise to be applicable for the design of many types of new bridges is efficient because the load and safety calculations become easy and because the extra cost due to the generalisation is marginal in the budget for a new bridge.

Smithfield Market Development (No. 16 Nov-03)

Smithfield Market Development in Dublin is a 4-acre site being developed for a mixed use including apartments, offices, hotel, retail, leisure, cultural space and a 3 level basement with formation some 6m below water table. The project currently under construction, is valued at circa €400m, and is currently the largest single-phase city-centre building project in Dublin.

Can Bridge Repair And Replacement Costs Be Reduced By Developing “Smart” Bridges? (No.15 May-03)

There is a lot of European research going on in bridge loading at the moment. The Eurocode for bridge loading, EC1, Part 3, is the first bridge loading code in the world to be based on statistical principles. With the techniques used to develop the EC1 notional traffic loading – equivalent of BS5400 “HA” – it is now possible to derive a site-specific traffic loading for a bridge that is being assessed. In many cases, particularly if the bridge is subject to a low traffic flow, it is possible to prove that bridges are safe even if they can only carry a small portion of what the assessment code prescribes.

Webwatch – Engineering The Limits On Lake Erie (No.15 May-03)

What does it take to build the world’s tallest and fastest roller coaster? The $25 million “strata-coaster” at Cedar Point will be the first scream machine in the world to break the 400-foot-tall mark. Riders will launch out of a “starting line” position and travel from 0 to 120mph in four seconds by use of a high-tech hydraulic acceleration system and then rocket up the vertical 420-foot-high hill, rotate 90 degrees, crest the apex and plummet straight down the 400-foot drop while spiraling 270 degree sand cross the finish line into the station.

Boyne Bridge (No.15 May-03)

The Boyne Bridge currently reaching completion will carry the M1 motorway across the Boyne River about 3km to the west of Drogheda.  The asymmetric cable stayed bridge in total 350m long crosses both streams of the river in a single stayed span of 170m.  Sited 20m above the river and with a pylon over 90m high, the structure provides a landmark along the scenic Boyne Valley.  The cable stayed form of bridge chosen was driven by the need to respect the environmentally sensitive nature of the river channels and the central island as well as matching the asymmetric nature of river valley at the crossing.
