E-book Timber Engineering : Principles for Design
Above all, the building authority centres on preventing dangers to the public, which may arise from the construction process. In Germany, the general conditions governing the building, alteration or demolition of structures have been a federal responsibility since the 19th century. Even so, individual tasks were transferred to the Deutsche Institut für Bautechnik (DIBt) in an agreement and this allocation of responsibilities, alongside Euro?pean rules which have to be implemented in Germany make it far from easy for structural engineers to decipher the current legal situation. The following article will provide an overview (including online references) of the relevant codes of practice for structural engineers. It is important to remember that regulations on national and European levels are prone to change and since reflecting all such changes in this article is impossible, only the basic context will be explained in this case. We advise structural engineers to check the current status of regulations (particularly the current list of Technical Building Rules, Section A1.2 and the current Construction Products Lists, Section A1.3) on the specified web pages. The building codes of the individual German federal state dictate the form of construc?tion supervision imposed, although these State Building Codes (LBOs) tend to follow the jointly compiled Model Building Code (MBO). The Model Building Code and the model ordinances of ARGEBAU can be viewed and downloaded on the ARGEBAU homepage (www.is?argebau.de; there: Mustervorschriften (model rules) / Mustererlasse (model decrees) / Bauaufsicht (construction supervision) / Bautechnik (construction technolo?gy)). However, the Model Building Code and model ordinances are not laws, but merely a framework providing guidance for the legal building regulations of each state. With sim?plicity in mind, the model regulations are adopted more or less uniformly across different federal states for construction products and types of construction. Even so, the regula?tions of individual federal states should still be taken into consideration. Regulation is also imposed through respective National Annexes (NA) and the Nationally Determined Parameters (NDP, such as partial safety factors or load duration classes). The NAs also contain non?contradictory complementary information (NCI) and member states cannot amend European standards. However, the application of EC 5 also requires compliance with additional provisions, con?tained in the annexes of the LTB. The relevant annexes for EC 5 are 2.5/1E and 2.5/2, which specify regulations to be complied with when using construction products in accordance with harmonised standards for timber structures. Here, reference is made to application standards (DIN V 20000?X), which also apply when using specific construction products in accordance with harmonised standards, although such use may also be excluded.
