Holzbrücken – Erkenntnisse zum Feuchteverhalten in den Tragquerschnitten aus Langzeitmessungen

Timber bridges – Long term monitoring results of moisture diffusion in the load carrying cross‐sections Timber road bridges have been built worldwide for centuries. The high performance of wood is approved through many constructions. However, there are still doubts about using wood by the planning engineer, which reduce the number of realized projects. The moisture induced stresses in cross‐sections according to the varied ambient climate are mainly investigated under laboratory conditions. The results show that the moisture content changes differently over the cross‐section and leads to moisture induced stresses. The discussion about methods for the assessment of the moisture induced stresses in timber bridge cross‐ections is continuing. Results observed in the long term monitoring of seven timber bridges provide first guidelines for practitioners. For all constructions, the moisture content was measured regarding the ambient micro climate. As result, the influences according to the ambient micro climate are not insignificant. Positive is that the directly measured moisture content is less compared to the equilibrium moisture content calculated from the data of a close by meteorological station. The analysis of the moisture gradient over the cross‐section allows the definition of an active or passive zone.     

Ersatzneubau der Kajen im Marinestützpunkt Wilhelmshaven

Replacement construction of quays at the naval base in Wilhelmshaven At the naval base of Wilhelmshaven the quay walls and dolphins of a floating bridge system are being renewed. The existing quays show extensive damage and stability deficits. In particular, microbially induced corrosion (MIC) on the back of the old sheet piling lead to rust corrosion of the old sheet pile walls. Content of the report is the conceptual and structural implementation of the measure quay renewal that has been executed since the beginning of 2013. Special attention is paid to the security of the stock during the construction period, the selected corrosion protection measures as well as the requirements for the installation of combined sheet piling.

建筑文化关联──中国传统建筑文化内涵

建筑是一种文化载体。纵观建筑历史长河,各个历史阶段的建筑都是作为一种文化现象深深地沉积下来。这些文化现象包括科学、艺术、宗教、道德、法律、风俗、习惯等等。它们都是人类物质与精神财富的沉淀,具有历史的延续性,同时反映着民族文化特征。本文从中国建筑伦理文化对空间组织的影响及中国传统建筑装饰两方面进行了论述。
