National Museum of Qatar

National Museum of Qatar – Super‐complex steel structures, envelope and 3D BIM. Doha, the capital of Qatar, is developing fast towards a global hub for finance, culture and tourism. The new flagship, the National Museum of Qatar (NMoQ), is currently being completed based on a design by Atelier Jean Nouvel, Paris. The iconic three‐dimensional geometry and the size of the project were extremely challenging for both the design and the works on site.     

Experimentelle Validierung von Bemessungsregeln für Stahltrapezprofile mit Öffnungen

Experimental validation of design rules for trapezoidal profiles with openings. Structural design and detailing of trapezoidal steel sheets in Germany currently follows the rules provided by the still valid National Standard DIN 18807‐3 (1987). This Standard is based on the old design concept using one global safety factor and contains references to outdated codes which had been long since withdrawn. Within the framework of transition of design rules from DIN 18807‐3 to the European Standard EN 1090‐4 available provisions for openings in trapezoidal profiles, which exist since 30 years, were brought into question. The investigations regarding background information on these rules revealed a number of open questions concerning their application in practice as well as the mechanical performance of the cover plates. The basic concept for consideration of openings consists of the application of increased loads and verification using the complete cross‐section of trapezoidal profiles. On the one head, several details regarding the application of this method are, however, not clearly specified leaving space for interpretations which may lead to non‐economic results in case of over‐conservative interpretation. On the other hand, non‐safe results may be obtained if neglecting the increased loads while relying on the (non‐existing) strengthening effect of the cover plates.     

Dendrochronologically Dated Pine Buildings from Scotland: The SCOT2K Native Pine Dendrochronology Project

The SCOT2K project has extended native pine tree-ring chronology coverage for Scotland to enable reconstruction of past climate and for cultural heritage dating benefits. Using living trees from multiple locations in the Highlands and sub-fossil material from lochs, a network of five regional chronologies has been produced. The project has developed the application of Blue Intensity (BI), a proxy measure for maximum latewood density, which is faster and less costly to obtain than traditional densitometry measurements. The use of both ring-width and BI has been demonstrated to greatly assist historical dendro-dating of pine. This paper presents the dating results for the twenty Scottish pine buildings or sites dendro-dated through the SCOT2K project. They range from the fifteenth to the nineteenth centuries, and from high-status castles to modest cruck cottages. They are mostly located in the Highlands where Scots pine occurs naturally, although an early example of long-distance transport is also identified.

高原城市中压天然气管道泄漏扩散的数值模拟

针对高原城市中压天然气管道泄漏情况,研究了多层、高层建筑物和风速对天然气管道泄漏和扩散的影响,利用CFD模拟计算软件分别对高原气压下中压A、中压B天然气管道的泄漏扩散进行数值模拟,并得到了泄漏后CH4的体积分数分布和危险区域。研究结果表明:高原城市中压A天然气管道泄漏孔处的质量流量与平原地区一致,不受气压影响,高原城市中压B天然气管道泄漏的危险区域随时间的增加保持不变或变小。
